THE CORONAVIRUS GROUP


Human Coronavirus Types

Coronaviruses are named for the crown-like spikes on their surface. There are four main sub-groupings of coronaviruses, known as alpha, beta, gamma, and delta.

Human coronaviruses were first identified in the mid-1960s. The seven coronaviruses that can infect people are:

Common human coronaviruses

229E (alpha coronavirus)
NL63 (alpha coronavirus)
OC43 (beta coronavirus)
HKU1 (beta coronavirus)

Other human coronaviruses

MERS-CoV (the beta coronavirus that causes Middle East Respiratory Syndrome, or MERS)
SARS-CoV (the beta coronavirus that causes severe acute respiratory syndrome, or SARS)
SARS-CoV-2 (the novel coronavirus that causes coronavirus disease 2019, or COVID-19)
People around the world commonly get infected with human coronaviruses 229E, NL63, OC43, and HKU1.

Sometimes coronaviruses that infect animals can evolve and make people sick and become a new human coronavirus. Three recent examples of this are 2019-nCoV, SARS-CoV, and MERS-CoV.

FOR THOSE OF US WHO SPEND A LOT OF TIME ON A COMPUTER, “GOING VIRAL” IS A COMMONLY UNDERSTOOD TERM. IT MEANS THAT A STORY OR MEME SPREADS NOT MERELY IN A DIRECTIONAL WAY, ONE PERSON AT A TIME, BUT RADIATES OUTWARD WITH A MINIMUM OF INITIAL CONTACT. WITH PANDEMIC COVID-19 DISEASE, IT IS TRANSMITTING MORE AND MORE VIRUSES IN A WIDESPREAD WAY, AT THIS MOMENT, AT THIS HOUR, AND MAYBE IN THIS PLACE, UNTIL LARGE NUMBERS OF PEOPLE CARRY IT OR DEVELOP SYMPTOMS. BECAUSE OF THAT, IT HAS THE CAPABILITY TO SWAMP HOSPITALS WITH MORE PATIENTS THAN THEY CAN TREAT OR EVEN HOUSE, AND THAT CAN HAPPEN ON A DAILY BASIS.

THE SPEED WITH WHICH THIS CORONAVIRUS INFECTS, AND SOMETIMES KILLS, IS ONE OF THE MOST FRIGHTENING PARTS OF THE COVID-19 VIRUS PANDEMIC. ALSO, LIKE THE OTHER SEVERE VIRUSES MENTIONED IN THE BLOG TITLE, IT HAS OTHER AND MORE SURPRISING SYMPTOMS. THE MOST RECENT TO BE REPORTED IN THE NEWS IS A STRANGE SET OF CONDITIONS THAT ARE SHOWING UP IN CHILDREN, BUT NOT SO FAR IN MATURE ADULTS. IT IS CALLED KAWASAKI DISEASE. IT IS UNCOMMON, BUT CAN BE LETHAL, AS IT AFFECTS SWELLING IN ORGANS INCLUDING THE HEART AND BLOOD VESSELS.

AS COMPARED TO THE FLU OR THE COMMON COLD, ONE OF THE THINGS THAT MAKES COVID-19 DANGEROUS IS THE FACT THAT IT, TOO, CAN BE SPREAD BY CONTACT WITH VIRUS LADEN DROPLETS FROM THE MOUTH OR NOSE, AND BY CONTACT ON SOLID SURFACES. THAT’S WHY THE “SOCIAL DISTANCING,” MASKS, HANDWASHING AND SANITIZER ARE SO IMPORTANT. IT IS UNFORTUNATE INDEED THAT THOSE THINGS ARE ALMOST THE ONLY EFFECTIVE PRACTICES THAT ARE HELPING SO FAR. THE SCIENTISTS ARE AT WORK ON BETTER TREATMENTS AND HOPEFULLY EVEN A VACCINE. THE TIME PERIOD NEEDED TO DEVELOP THOSE THINGS IS DAUNTING, THOUGH, SO WE ARE ALL WAITING FOR THE NUMBER OF NEW CASES TO GO DOWN RATHER THAN UP.

THE GOOD THING ABOUT RABIES OR EBOLA, IF THERE IS SOMETHING GOOD, IS THAT IT IS NOT SPREAD BY THE AIR AS COVID IS. IT TAKES CLOSE CONTACT, AND IN THE CASE OF RABIES IT USUALLY REQUIRES A BREAK IN THE SKIN OR MUCOUS MEMBRANE, MOST OFTEN A SCRATCH OR BITE. EBOLA, HOWEVER, IS SPREAD BY SIMPLE PHYSICAL CONTACT WITH A PATIENT, AND ONE THING THAT CAUSED IT TO SPREAD SO RAPIDLY IN AFRICA WAS THE TIME HONORED CULTURAL HABIT OF WASHING AND MAKING CLOSE PHYSICAL CONTACT WITH THE DEAD PRIOR TO THE FUNERAL. WHOLE FAMILIES AND NEIGHBORS WERE BEING INFECTED.

FINALLY, COMPARED TO INFLUENZA, COVID KILLS AT A HIGHER RATE, ALTHOUGH PEOPLE ALSO DIE FROM INFLUENZA EVERY YEAR. ON DEATH AND INFECTION RATES, SEE THE ARTICLES FROM ALJAZEERA BELOW, THE CDC COMPARISONS AND THE ONE FROM LIVESCIENCE.COM ON THOSE STATISTICS AND SYMPTOMS. THE CDC ARTICLE IS PARTICULARLY GOOD AS A SOURCE FOR BASIC INFORMATION, HOME CARE, ETC.    

AS WITH THE INFAMOUS CASE OF TYPHOID MARY, SOME PEOPLE CAN CARRY COVID-19 AND SPREAD IT BUT NOT BECOME ILL THEMSELVES, SO THAT THEY HAVE NO IDEA THEY ARE THE CAUSE OF OTHER PEOPLE’S SICKNESS. TYPHOID FEVER IS NOT CAUSED BY A VIRUS, BUT RATHER BY A FORM OF THE SALMONELLA BACTERIA AND SPREADS FROM CONTAMINATED FOOD OR WATER, BUT IT IS DEADLY NONETHELESS IN “UP TO 10%” OF THOSE WHO CONTRACT IT. FOR TYPHOID, WE DO HAVE AN INJECTABLE VACCINE AND A PILL FORM TO PREVENT THE ILLNESS BY STIMULATING ANTIBODY FORMATION, BUT IT WORKS FOR A RELATIVELY SHORT PERIOD OF TIME – A FEW YEARS. WITH THAT DISEASE, PUBLIC SANITATION IS KEY. WHEN MY PARENTS WERE GROWING UP, TYPHOID WAS AN ILLNESS AS FRIGHTENING AS COVID-19 IS NOW.

COMPARATIVE INFORMATION ON CORONAVIRUSES, INCLUDING DEATH RATES

Coronavirus: Comparing COVID-19, SARS and MERS
A comparison of COVID-19 data to similar recent diseases with global impact caused by the coronavirus.

PHOTOGRAPH -- As of April 7, the number of global COVID-19 cases was more than 1,360,000 with over 76,000 deaths [Brendan Mcdermid/Reuters]

The new coronavirus outbreak has spread rapidly around the world, affecting more than 183 countries and territories, infecting over a million and killing more than 80,000 people.

It is reported to have emerged in China's Hubei province late last year.

On March 11, the World Health Organization (WHO) declared the outbreak of the coronavirus a pandemic, which it defines as "global spread of a new disease".

*What we know so far about coronavirus
*Coronavirus: All you need to know about symptoms and risks


Governments have imposed tough measures, including travel restrictions and curfews, to contain the spread of the virus as scientists worldwide race to find a vaccine.

This is not the first time an international health crisis occurred due to the spread of a novel coronavirus or other zoonotic (animal-originated) viruses, such as influenza that created the swine, bird and seasonal flu epidemics in recent history.

Seasonal flu alone is estimated to result in three to five million cases of severe illness, and 290,000 to 650,000 respiratory deaths annually.


INTERACTIVE: Coronavirus outbreaks April 8 2020


Here is a comparison of the information and data we have on COVID-19, the disease caused by the new coronavirus, with similar recent coronavirus-related diseases.


COVID-19

As of April 7, 2020, the number of global COVID-19 cases was more than 1,290,000 with over 76,000 deaths.

While a few regions, such as China's Hubei province and South Korea, report falling numbers of new local cases, the number of infections keeps rising across the world.

Although the source of the virus is suggested to be animals, the specific species is yet to be confirmed.

The main symptoms of COVID-19 are fever, tiredness and dry cough, the WHO said, adding that some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhoea.

According to the WHO, approximately one out of every six infected people becomes seriously ill and develops difficulty in breathing.

R0

The R0 (pronounced R-naught), is a mathematical term to measure how contagious and reproductive an infectious disease is as it displays the average number of people that will be infected from a contagious person.

The WHO puts the R0 of COVID-19 at 2 to 2.5.


SARS

Severe acute respiratory syndrome (SARS), also caused by a coronavirus, was first reported in November 2002 in the Guangdong province of southern China.

The viral respiratory illness spread to 29 countries across multiple continents before it was contained in July the following year.

Between its emergence and May 2014, when the last case was reported, 8,098 people were infected and 774 of them died.

Various studies and the WHO suggest that the coronavirus that caused SARS originated from bats, and it was transmitted to humans through an intermediate animal - civet cats.

Symptoms of SARS are flu-like, such as fever, malaise, myalgia, headache, diarrhoea, and shivering. No other additional symptom has proved to be specific for the diagnosis of SARS.

The R0 of SARS is estimated to range between 2 and 4, averaging at 3, meaning it is highly contagious.


MERS

The Middle East respiratory syndrome (MERS) is a still active viral respiratory disease first identified in Saudi Arabia in 2012.

Approximately 80 percent of human cases were reported by the kingdom, but it has been reported in 27 countries.

As of March 2020, 2,521 MERS cases were confirmed globally with 866 deaths due to the illness, mainly in Saudi Arabia.

According to WHO, dromedary camels are a large reservoir host for MERS and an animal source of MERS infection in humans.

However, human cases of MERS infections have been predominantly caused by human-to-human transmissions.

MERS might show no symptoms, mild respiratory symptoms or severe acute respiratory disease and death. Fever, cough and shortness of breath are common symptoms.

If it gets severe, it might cause respiratory failure* that requires mechanical ventilation.

R0 of MERS is lower than one, identifying it as it is a mildly contagious disease.

RESPIRATORY FAILURE*

IN SHORT, RESPIRATORY FAILURE IS THE CONDITION OF LOW OXYGEN OR HIGH CARBON DIOXIDE IN THE BLOOD, CAUSED BY SEVERAL BREATHING RELATED ISSUES, AND IS THE CONDITION WHICH NECESSITATES A VENTILATOR. A LACK OF SUCH VENTILATORS WAS THE REASON WHY SO MANY HOSPITALS HAVE BEEN UNABLE TO PROPERLY CARE FOR COVID PATIENTS OVER THE LAST FEW MONTHS. READ THIS INTERESTING AND WELL-EXPLAINED ARTICLE.

Respiratory Failure

Summary

What is respiratory failure?

Respiratory failure is a condition in which your blood doesn't have enough oxygen or has too much carbon dioxide. Sometimes you can have both problems.

When you breathe, your lungs take in oxygen. The oxygen passes into your blood, which carries it to your organs. Your organs, such as your heart and brain, need this oxygen-rich blood to work well.

Another part of breathing is removing the carbon dioxide from the blood and breathing it out. Having too much carbon dioxide in your blood can harm your organs.

What causes respiratory failure?

Conditions that affect your breathing can cause respiratory failure. These conditions may affect the muscles, nerves, bones, or tissues that support breathing. Or they may affect the lungs directly. These conditions include:

*Lung diseases such as COPD (chronic obstructive pulmonary disease), cystic fibrosis, pneumonia, and pulmonary embolism
*Conditions that affect the nerves and muscles that control breathing, such as amyotrophic lateral sclerosis (ALS), muscular dystrophy, spinal cord injuries, and stroke
*Problems with the spine, such as scoliosis (a curve in the spine). They can affect the bones and muscles used for breathing.
*Damage to the tissues and ribs around the lungs. An injury to the chest can cause this damage.
*Drug or alcohol overdose
*Inhalation injuries, such as from inhaling smoke (from fires) or harmful fumes

What are the symptoms of respiratory failure?

The symptoms of respiratory failure depend on the cause and the levels of oxygen and carbon dioxide in your blood.

A low oxygen level in the blood can cause shortness of breath and air hunger (the feeling that you can't breathe in enough air). Your skin, lips, and fingernails may also have a bluish color. A high carbon dioxide level can cause rapid breathing and confusion.

Some people who have respiratory failure may become very sleepy or lose consciousness. They also may have arrhythmia (irregular heartbeat). You may have these symptoms if your brain and heart are not getting enough oxygen.



I HAVE BEEN HEARING THE TERM “RESPIRATOR” BEING USED IN TWO WAYS, AS AN AIR CIRCULATING MACHINE AND AS A SPECIALIZED MASK. THE N95 IS SUCH A MASK. THE OTHER TERM IS “VENTILATOR.” FROM THE POLIO YEARS, THE TERM “IRON LUNG” WAS USED ON SOME NEWS REPORTS. SO HERE IS A RUNDOWN ON THOSE THREE TERMS.

THE OTHER DEVICE WHICH HAS BEEN USED FOR COVID-19 PATIENTS DUE TO THE LACK OF VENTILATORS AROUND THE COUNTRY IS THE SMALLER AND MORE WELL-KNOWN “CPAP” MACHINE THAT IS USED FOR A COMMON, BUT SOMETIMES DANGEROUS CONDITION CALLED SLEEP APNEA, WHICH CAN LEAD TO A TYPE OF HEART ATTACK. SO, SEE THIS FROM WIKIPEDIA.

Ventilator
From Wikipedia, the free encyclopedia
  (Redirected from Medical ventilator)

This article is about one type of machine used to assist breathing. For the broader article, on both positive- and negative-pressure devices, see Mechanical ventilation. For respiratory PPE worn on the face, see Respirator. For ventilation subjects, see Ventilation. For other uses, see Ventilator (disambiguation).

A ventilator is a machine that provides mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. Modern ventilators are computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask. Ventilators are chiefly used in intensive-care medicine, home care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia machine).

Ventilators are sometimes called "respirators", a term commonly used for them in the 1950s (particularly the "Bird respirator"). However, contemporary hospital and medical terminology uses the word "respirator" to refer to a protective face-mask.[1]


IRON LUNG

Iron lung
From Wikipedia, the free encyclopedia

An iron lung, also known as a tank ventilator or Drinker tank, is a type of negative pressure ventilator, a mechanical respirator which encloses most of a person's body, and varies the air pressure in the enclosed space, to stimulate breathing.[1][2][3][4] It assists breathing when muscle control is lost, or the work of breathing exceeds the person's ability.[1] Need for this treatment may result from diseases including polio and botulism and certain poisons (for example, barbiturates, tubocurarine).

The use of iron lungs is largely obsolete in modern medicine, as superior breathing therapies have been developed[citation needed], and due to the eradication of polio in most of the world.[5] However, in 2020, the COVID-19 pandemic revived some interest in the device as a cheap, readily-producible substitute for positive-ventilation ventilators, which were feared to be outnumbered by potential victims temporarily needing artificially assisted respiration.[6][7][8][9]


N95 Respirators and Surgical Masks (Face Masks)

N95 respirators and surgical masks (face masks) are examples of personal protective equipment that are used to protect the wearer from airborne particles and from liquid contaminating the face. Centers for Disease Control and Prevention (CDC) National Institute for Occupational Safety and Health (NIOSH) and Occupational Safety and Health Administration (OSHA) also regulate N95 respirators.

It is important to recognize that the optimal way to prevent airborne transmission is to use a combination of interventions from across the hierarchy of controls, not just PPE alone.


N95 Respirators

An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles.

The 'N95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles. If properly fitted, the filtration capabilities of N95 respirators exceed those of face masks. However, even a properly fitted N95 respirator does not completely eliminate the risk of illness or death.


MICROPROCESSOR

Microprocessor

A microprocessor is an electronic component that is used by a computer to do its work. It is a central processing unit on a single integrated circuit chip containing millions of very small components including transistors, resistors, and diodes that work together. Some microprocessors in the 20th century required several chips. Microprocessors help to do everything from controlling elevators to searching the Web. Everything a computer does is described by instructions of computer programs, and microprocessors carry out these instructions many millions of times a second. [1]

Microprocessors were invented in the 1970s for use in embedded systems. The majority are still used that way, in such things as mobile phones, cars, military weapons, and home appliances. Some microprocessors are microcontrollers, so small and inexpensive that they are used to control very simple products like flashlights and greeting cards that play music when you open them. A few especially powerful microprocessors are used in personal computers.





THE CDC ON CORONAVIRUS

Symptoms of Coronavirus  

Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness.

Chat icon
Self-Checker
A guide to help you make decisions and seek appropriate medical care.

Watch for symptoms

People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness.

Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms or combinations of symptoms may have COVID-19:

Cough
Shortness of breath or difficulty breathing
Or at least two of these symptoms:

Fever
Chills
Repeated shaking with chills
Muscle pain
Headache
Sore throat
New loss of taste or smell
Children have similar symptoms to adults and generally have mild illness.

This list is not all inclusive. Please consult your medical provider for any other symptoms that are severe or concerning to you.

When to Seek Medical Attention
If you have any of these emergency warning signs* for COVID-19 get medical attention immediately:

Trouble breathing
Persistent pain or pressure in the chest
New confusion or inability to arouse
Bluish lips or face
*This list is not all inclusive. Please consult your medical provider for any other symptoms that are severe or concerning to you.

Call 911 if you have a medical emergency: Notify the operator that you have, or think you might have, COVID-19. If possible, put on a cloth face covering before medical help arrives.

Caring for Someone Sick at Home, or other non-healthcare settings

Advice for caregivers

If you are caring for someone with COVID-19 at home or in a non-healthcare setting, follow this advice to protect yourself and others. Learn what to do when someone has symptoms of COVID-19. or when someone has been diagnosed with the virus. This information also should be followed when caring for people who have tested positive but are not showing symptoms.

*Note: Older adults and people of any age with serious underlying medical conditions are at higher risk for developing more severe illness from COVID-19. People at higher risk of severe illness should call their doctor as soon as symptoms start.

Provide support and help cover basic needs

Help the person who is sick follow their doctor’s instructions for care and medicine.
For most people, symptoms last a few days, and people usually feel better after a week.

See if over-the-counter medicines for fever, such as acetaminophen (sometimes called Tylenol), help the person feel better.
Make sure the person who is sick drinks a lot of fluids and rests.
Help them with grocery shopping, filling prescriptions, and getting other items they may need. Consider having the items delivered through a delivery service, if possible.
Take care of their pet(s), and limit contact between the person who is sick and their pet(s) when possible.


Watch for warning signs

Have their doctor’s phone number on hand.
Use CDC’s self-checker tool to help you make decisions about seeking appropriate medical care.
Call their doctor if the person keeps getting sicker. For medical emergencies, call 911 and tell the dispatcher that the person has or might have COVID-19.
People who have emergency warning signs for COVID-19 should  call 911 right away. Emergency warning signs include*:
Difficulty breathing or shortness of breath
Persistent pain or pressure in the chest
New confusion or inability to wake up
Bluish lips or face
*This is not every emergency symptom or sign.

Protect yourself when caring for someone who is sick
people arrows icon

Limit contact

COVID-19 spreads between people who are in close contact (within about 6 feet) through respiratory droplets, created when someone talks, coughs or sneezes.

The caregiver, when possible, should not be someone who is at higher risk for severe illness from COVID-19.

Use a separate bedroom and bathroom. If possible, have the person who is sick stay in their own “sick room” or area and away from others. If possible, have the person who is sick use a separate bathroom.
Shared space: If you have to share space, make sure the room has good air flow.

Open the window and turn on a fan (if possible) to increase air circulation.
Improving ventilation helps remove respiratory droplets from the air.
Avoid having visitors. Avoid having any unnecessary visitors, especially visits by people who are at higher risk for severe illness.
food icon

Eat in separate rooms or areas

Stay separated: The person who is sick should eat (or be fed) in their room, if possible.
Wash dishes and utensils using gloves and hot water: Handle any dishes, cups/glasses, or silverware used by the person who is sick with gloves. Wash them with soap and hot water or in a dishwasher.
Clean hands after taking off gloves or handling used items.
no icon

Avoid sharing personal items

Do not share: Do not share dishes, cups/glasses, silverware, towels, bedding, or electronics (like a cell phone) with the person who is sick.
head side mask icon
When to wear a cloth face cover or gloves

Sick person:

The person who is sick should wear a cloth face covering when they are around other people at home and out (including before they enter a doctor’s office).
The cloth face covering helps prevent a person who is sick from spreading the virus to others. It keeps respiratory droplets contained and from reaching other people.
Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is not able to remove the covering without help.

Caregiver:

Wear gloves when you touch or have contact with the sick person’s blood, stool, or body fluids, such as saliva, mucus, vomit, and urine. Throw out gloves into a lined trash can and wash hands right away.
The caregiver should ask the sick person to put on a cloth face covering before entering the room.

The caregiver may also wear a cloth face covering when caring for a person who is sick.

To prevent getting sick, make sure you practice everyday preventive actions: clean hands often; avoid touching your eyes, nose, and mouth with unwashed hands; and frequently clean and disinfect surfaces.

Note: During the COVID-19 pandemic, medical grade facemasks are reserved for healthcare workers and some first responders. You may need to make a cloth face covering using a scarf or bandana. Learn more here.

hands wash icon
Clean your hands often

Wash hands: Wash your hands often with soap and water for at least 20 seconds. Tell everyone in the home to do the same, especially after being near the person who is sick.
Hand sanitizer: If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
Hands off: Avoid touching your eyes, nose, and mouth with unwashed hands.

Clean and then disinfect
Around the house

Clean and disinfect “high-touch” surfaces and items every day: This includes tables, doorknobs, light switches, handles, desks, toilets, faucets, sinks, and electronics.
Clean the area or item with soap and water if it is dirty. Then, use a household disinfectant.

Be sure to follow the instructions on the label to ensure safe and effective use of the product. Many products recommend keeping the surface wet for several minutes to kill germs. Many also recommend wearing gloves, making sure you have good air flow, and wiping or rinsing off the product after use.

Most household disinfectants should be effective. A list of EPA-registered disinfectants can be found hereexternal icon.
To clean electronics, follow the manufacturer’s instructions for all cleaning and disinfection products. If those directions are not available, use alcohol-based wipes or spray containing at least 70% alcohol.

Bedroom and Bathroom

If you are using a separate bedroom and bathroom: Only clean the area around the person who is sick when needed, such as when the area is soiled. This will help limit your contact with the sick person.

If they feel up to it, the person who is sick can clean their own space. Give the person who is sick personal cleaning supplies such as tissues, paper towels, cleaners, and EPA-registered disinfectantsexternal icon.

If sharing a bathroom: The person who is sick should clean and then disinfect after each use. If this is not possible, wear a mask and wait as long as possible after the sick person has used the bathroom before coming in to clean and use the bathroom.
washer icon

Wash and dry laundry

Do not shake dirty laundry.
Wear disposable gloves while handling dirty laundry.
Dirty laundry from a person who is sick can be washed with other people’s items.
Wash items according to the label instructions. Use the warmest water setting you can.
Remove gloves, and wash hands right away.
Dry laundry, on hot if possible, completely.
Wash hands after putting clothes in the dryer.
Clean and disinfect clothes hampers. Wash hands afterwards.
trash icon

Use lined trash can

Place used disposable gloves and other contaminated items in a lined trash can.
Use gloves when removing garbage bags, and handling and disposing of trash. Wash hands afterwards.
Place all used disposable gloves, facemasks, and other contaminated items in a lined trash can.
If possible, dedicate a lined trash can for the person who is sick.
digital thermometer icon

Track your own health

Caregivers and close contacts should monitor their health for COVID-19 symptoms.
Symptoms include fever, cough, and shortness of breath but other symptoms may be present as well. Trouble breathing is a more serious warning sign that you need medical attention.
Use CDC’s self-checker tool to help you make decisions about seeking appropriate medical care.
If you are having trouble breathing, call 911.
Call your doctor or emergency room and tell them your symptoms before going in. They will tell you what to do.
How to discontinue home isolation
house leave icon
People with COVID-19 who have stayed home (home isolated) can leave home under the following conditions**:

If they have not had a test to determine if they are still contagious, they can leave home after these three things have happened:
They have had no fever for at least 72 hours (that is three full days of no fever without the use of medicine that reduces fevers)
AND
other symptoms have improved (for example, symptoms of cough or shortness of breath have improved)
AND
at least 10 days have passed since their symptoms first appeared
If they have had a test to determine if they are still contagious, they can leave home after these three things have happened:
They no longer have a fever (without the use of medicine that reduces fevers)
AND
other symptoms have improved (for example, symptoms of cough or shortness of breath have improved)
AND
they have received two negative tests in a row, at least 24 hours apart. Their doctor will follow CDC guidelines.
People who DID NOT have COVID-19 symptoms, but tested positive and have stayed home (home isolated) can leave home under the following conditions**:

If they have not had a test to determine if they are still contagious, they can leave home after these two things have happened:
At least 10 days have passed since the date of their first positive test
AND
they continue to have no symptoms (no cough or shortness of breath) since the test.
If they have had a test to determine if they are still contagious, they can leave home after:
They have received two negative tests in a row, at least 24 hours apart. Their doctor will follow CDC guidelines.
Note: if they develop symptoms, follow guidance above for people with COVID19 symptoms.

For ALL people

When leaving the home, keep a distance of 6 feet from others and wear a cloth face covering when around other people.

**In all cases, follow the guidance of your doctor and local health department. The decision to stop home isolation should be made in consultation with their healthcare provider and state and local health departments. Some people, for example those with conditions that weaken their immune system, might continue to shed virus even after they recover.

Q&A FROM THE WORLD HEALTH ORGANIZATION

Q&A: Similarities and differences – COVID-19 and influenza
17 March 2020 | Q&A

As the COVID-19 outbreak continues to evolve, comparisons have been drawn to influenza. Both cause respiratory disease, yet there are important differences between the two viruses and how they spread. This has important implications for the public health measures that can be implemented to respond to each virus.

How are COVID-19 and influenza viruses similar?
Firstly, COVID-19 and influenza viruses have a similar disease presentation. That is, they both cause respiratory disease, which presents as a wide range of illness from asymptomatic or mild through to severe disease and death.

Secondly, both viruses are transmitted by contact, droplets and fomites*. As a result, the same public health measures, such as hand hygiene and good respiratory etiquette (coughing into your elbow or into a tissue and immediately disposing of the tissue), are important actions all can take to prevent infection.

How are COVID-19 and influenza viruses different?
The speed of transmission is an important point of difference between the two viruses. Influenza has a shorter median incubation period (the time from infection to appearance of symptoms) and a shorter serial interval (the time between successive cases) than COVID-19 virus. The serial interval for COVID-19 virus is estimated to be 5-6 days, while for influenza virus, the serial interval is 3 days. This means that influenza can spread faster than COVID-19.

Further, transmission in the first 3-5 days of illness, or potentially pre-symptomatic transmission –transmission of the virus before the appearance of symptoms – is a major driver of transmission for influenza. In contrast, while we are learning that there are people who can shed COVID-19 virus 24-48 hours prior to symptom onset, at present, this does not appear to be a major driver of transmission.

The reproductive number – the number of secondary infections generated from one infected individual – is understood to be between 2 and 2.5 for COVID-19 virus, higher than for influenza. However, estimates for both COVID-19 and influenza viruses are very context and time-specific, making direct comparisons more difficult. 

Children are important drivers of influenza virus transmission in the community. For COVID-19 virus, initial data indicates that children are less affected than adults and that clinical attack rates in the 0-19 age group are low. Further preliminary data from household transmission studies in China suggest that children are infected from adults, rather than vice versa.

While the range of symptoms for the two viruses is similar, the fraction with severe disease appears to be different. For COVID-19, data to date suggest that 80% of infections are mild or asymptomatic, 15% are severe infection, requiring oxygen and 5% are critical infections, requiring ventilation. These fractions of severe and critical infection would be higher than what is observed for influenza infection.

Those most at risk for severe influenza infection are children, pregnant women, elderly, those with underlying chronic medical conditions and those who are immunosuppressed. For COVID-19, our current understanding is that older age and underlying conditions increase the risk for severe infection.

Mortality for COVID-19 appears higher than for influenza, especially seasonal influenza. While the true mortality of COVID-19 will take some time to fully understand, the data we have so far indicate that the crude mortality ratio (the number of reported deaths divided by the reported cases) is between 3-4%, the infection mortality rate (the number of reported deaths divided by the number of infections) will be lower. For seasonal influenza, mortality is usually well below 0.1%. However, mortality is to a large extent determined by access to and quality of health care.

What medical interventions are available for COVID-19 and influenza viruses?
While there are a number of therapeutics currently in clinical trials in China and more than 20 vaccines in development for COVID-19, there are currently no licensed vaccines or therapeutics for COVID-19.  In contrast, antivirals and vaccines available for influenza. While the influenza vaccine is not effective against COVID-19 virus, it is highly recommended to get vaccinated each year to prevent influenza infection.


FOMITES*

CONTEXT: “Secondly, both viruses are transmitted by contact, droplets and fomites*.”

DICTIONARY


fomite
 noun

fo·​mite | \ ˈfō-ˌmīt  \
plural fomites\ ˈfō-​ˌmīts  ; ˈfä-​mə-​ˌtēz  , ˈfō-​  \

Definition of fomite

: an object (such as a dish, doorknob, or article of clothing) that may be contaminated with infectious agents (such as bacteria or viruses) and serve in their transmission

Did You Know?

Disinfectant on your hands keeps us healthier and fomites no longer foment as much disease. Australian newspaper contributor Peter Goers was likely going for alliteration when he paired up "fomite" and "foment," a verb meaning "to promote the growth or development of"-but, whether he realized it or not, the words "fomite" and "foment" are also related. "Fomite" is a back-formation of "fomites," the Latin plural of "fomes," itself a word for tinder. (Much like tinder is a catalyst of fire, a fomite can kindle disease.) "Fomes" is akin to the Latin verb fovēre ("to heat"), an ancestor of "foment."

THERE IS A VERY INTERESTING ARTICLE ON RABIES BELOW, WHICH IS PROBABLY THE MOST SHOCKING OF ALL THE VIRUSES DUE TO ITS EFFECTS AND THE NEAR INEVITABILITY OF CONTRACTING THE DISEASE IF BITTEN BY ANY NUMBER OF MAMMALS, NOT JUST DOGS OR CATS AND THEN OF DYING FROM IT. A FEW PEOPLE WHO DO DEVELOP SYMPTOMS OF RABIES HAVE ACTUALLY SURVIVED IT, THOUGH, WHICH IS THE SUBJECT OF THE ARTICLE.

FOR THOSE WHO ENJOY SUCH MATERIAL, THERE IS A VERY READABLE AND EVEN ENTERTAINING NONFICTION STUDY OF RABIES RELATED LITERATURE BOTH TODAY AND DOWN THROUGH TIME, INCLUDING MENTIONS IN WRITTEN SOURCES OF CLASSICAL TIMES, SEE THE AUTHORS BILL WASIK AND MONIKA MURPHY’S “RABID: A CULTURAL HISTORY OF THE WORLD’S MOST DIABOLICAL VIRUS,” AVAILABLE FROM AMAZON AT https://www.amazon.com/Rabid-Cultural-History-Worlds-Diabolical-ebook/dp/B0072NWKG0 .  

THE SURVIVAL OF A FEW PEOPLE ILL WITH A USUALLY DEADLY DISEASE IS TRUE ALSO ABOUT EBOLA, AS THE GREAT NON-FICTION BOOK ON THE SUBJECT, “THE HOT ZONE,” TELLS. THAT AUTHOR IS RICHARD PRESTON. IT DESCRIBES, AMONG MANY OTHER PIECES OF INFORMATION, HOW ONE AFRICAN DOCTOR USED A NON-APPROVED METHOD OF TREATING EBOLA. HE TRANSFUSED THE BLOOD OF ONE OF THE FEW RECOVERED PATIENTS INTO THE ARM OF A NEWLY ILL PATIENT, AND IT SEEMED TO MITIGATE THE SYMPTOMS AND POSSIBLY HELP THAT PERSON TO SURVIVE.

Medical Mystery: Only One Person Has Survived Rabies without Vaccine--But How?
ScientificAmerican.com talks with the first known survivor of rabies four years later
By Jordan Lite on October 8, 2008

Four years after she nearly died from rabies, Jeanna Giese is being heralded as the first person known to have survived the virus without receiving a preventative vaccine. But Giese (pronounced Gee-See) says she would gladly share that honor with others if only doctors could show that the treatment used to save her could spare other victims as well. "They shouldn't stop 'till it's perfected," said Giese, now 19, during a recent interview about physicians' quest to refine the technique that may have kept her alive.

Giese's wish may come true. Another young girl infected with rabies is still alive more than a month after doctors induced a coma to put her symptoms on hold, just as they did with Giese. Yolanda Caicedo, an infectious disease specialist at Hospital Universitario del Valle in Cali, Colombia, who is treating the latest survivor, confirmed reports in the Colombian newspaper El País that the victim is an eight-year-old girl who came down with symptoms in August, about a month after she was bitten by an apparently rabid cat. Caicedo said that the family had sought treatment for the bite in Bolivar, at a hospital about three hours by foot from their rural home, but that the child, Nelsy Gomez, did not receive the series of vaccines that can prevent the virus from turning into full-blown rabies.

The five shots contain minute amounts of the dead rabies virus and are designed to nudge the body into developing antibodies to fight it. Patients are also given a shot of immunoglobulin (in this case a synthesized rabies antibody) to protect them while their immune systems produce antibodies to the vaccine virus. But the combination is only effective within six days of infection, before symptoms show up; when Gomez developed signs of the disease, it was too late for the shots. With no other options available, doctors induced a coma.

Caicedo is hopeful, but indicated that Gomez will face a long, slow recovery. She would not say how long Gomez was comatose but told ScientificAmerican.com that she had been awake for "a few days" and is stable. The child can move her fingers but cannot walk or eat on her own, and her eyes are open but she cannot speak yet and physicians are not sure if she can see, Caicedo says.

Giese, informed of the case, says that she "hopes and prays" that Gomez will survive.

Giese was the keynote speaker at a conference last week in Atlanta, where scientists gathered to discuss the latest research being conducted on ways to battle the deadly disease. During her talk, she urged physicians to continue efforts to pin down treatments that work.

Giese was 15 when she was infected after being bitten by a rabid bat she had picked up outside her church in her hometown of Fond du Lac, Wisc.

Her parents cleaned the superficial wound and she says they did not believe it was necessary to seek further medical treatment. "We never thought of rabies," she says. By the time Giese began displaying signs of rabies three weeks later—fatigue, double vision, vomiting and tingling in her left arm—it was too late for the antirabies vaccine cocktail.

Instead of giving her up for dead, the doctors decided to "shut the brain down and wait for the cavalry to come" by inducing a coma to give her own immune system time to build up antibodies against the virus, says Rodney Willoughby, an infectious disease specialist who treated Giese at the Children's Hospital of Wisconsin in Milwaukee. Willoughby devised the treatment credited with saving Giese there, which has since become known as the Milwaukee protocol*.

Rabies kills by compromising the brain's ability to regulate breathing, salivation and heartbeat; ultimately, victims drown in their own spit or blood, or cannot breathe because of muscle spasms in their diaphragms. One fifth die from fatal heart arrhythmia. Doctors believed that Giese might survive if they suppressed her brain function by sedating her while her immune system attacked the rabies virus.

This was the first time the therapy was attempted, and doctors had no clue if it would work or, if it did, whether it would leave her brain damaged. But Willoughby says it was the only chance doctors had of saving her.

When she arrived at the hospital, Giese couldn't talk, sit or stand and fell in and out of consciousness—she also needed to be intubated to help her breathe. "She was critically ill," Willoughby recalls, "and looked as if she might die within the day."

In addition to inducing the coma, doctors also gave her the antivirals ribavarin and amantadine. They tapered off the anesthetics after about a week, when tests showed that Giese's immune system was battling the virus. For about six months after awakening from the coma, physicians also gave her a compound called tetrahydrobiopterin that is chemically similar to the B-complex vitamin folic acid, which may have improved her speech and ability to eat, Willoughby says.

He notes that physicians gave her the supplement after tests showed that she had a deficiency of the compound, which is known to boost production of serotonin and dopamine neurotransmitters needed to perform motor, speech and other routine bodily functions.

Remarkably, Giese survived. She recovered most of her cognitive functions within a few months, and other skills within a year, Willoughby says. She got her driver's license and is now a sophomore at Marian University in Fond du Lac, where she is majoring in biology. There are lingering signs of her illness: Giese, once an avid athlete, says she now lists to one side when she runs and walks and no longer plays volleyball, basketball and softball as she once did. She also speaks more slowly and sometimes not as clearly as before her illness, but Willoughby says these effects may fade over time.

Giese is "pretty much normal," says Willoughby, an associate professor of pediatrics at the Medical College of Wisconsin in Milwaukee. "She continues to get better, counter to conventional medical thinking."

Rabies has an incubation period of two weeks to three months and kills within a week of the symptoms showing up. The vaccine series and other immune therapies are useless at this point and may even speed up and increase the severity of the symptoms. Usually, patients are made as comfortable as possible in the hospital or, in countries without sophisticated health care, sent home to die an agonizing death.

Antiviral drugs and immune therapies including steroids, disease-fighting interferon-alpha and poly IC (which stimulates the body's own production of interferon-alpha) have been tried, but none have been shown to be lifesaving on their own, Willoughby says.

Over the past four years, the Milwaukee protocol to differing degrees has been used a dozen times, but until now Giese was the sole survivor. Exactly why she lived—and the others died—is still a mystery.

In a 2005 report on her case in The New England Journal of Medicine, Willoughby speculated that she may have been infected with a rare, weakened version of the virus. Today, he chalks Giese's survival up to aggressive intensive care, the decision to sedate her "and 10 percent sheer luck." Which element of that combination made the difference, and whether the antivirals she was given helped save her is unknown.

"In all honesty, we were probably just pretty lucky," he says. Only another survivor, and then animal and clinical trials, will show if the therapy works, and why, he says. The U.S. Centers for Disease Control and Prevention (CDC) plans to test the protocol on rabies-infected ferrets; Thai and Canadian doctors, who unsuccessfully treated a 33-year-old man with rabies with the Milwaukee protocol, recommended in the Journal of NeuroVirology two years ago that physicians exercise "caution" in using the treatment, because it is too expensive and lacks " a clear scientific rationale." Willoughby says it cost about $800,000 to treat Giese.

Rabies is 100 percent preventable with vaccinations if patients receive them before the onset of symptoms, including hallucinations, delirium, muscle spasms, paralysis and hydrophobia. Yet an estimated 55,000  people, mostly in Asia and Africa, die from it annually because of misdiagnosis or because the illness is not recognized until it has taken hold, according to the journal Neurologic Clinics. Often, patients dismiss the potential seriousness of bites, cannot afford follow-up medical treatment or, in some situations, are unaware they've been bitten, as was the case of a 13-year-old Connecticut girl who died of rabies in 1995.

Vaccine shortages as one manufacturer, Bridgewater, N.J.–based sanofi–aventis, upgrades its factory to meet U.S. Food and Drug Administration requirements, and chronic shortfalls of immunoglobulin also play a role in the fatalities. The vaccine-immunoglobulin regimen costs $1,200 to $2,000 in industrialized nations and $100 to $300 in developing countries—an out-of-reach sum for many people, Willoughby says.

Though it's promising that Gomez is still alive, "The hope that the outcome will necessarily be the same as with Jeanna, particularly in a developing country, is expecting a bit much," laments Charles Rupprecht, chief of the CDC's Rabies Program

Willoughby acknowledges that even if Giese's success is reproducible—and the Milwaukee protocol perfected—it likely will only be available for use in 10 percent of cases, because of limited medical facilities in developing countries.

"Re-creating that in a place stricken with poverty, you get into ethical issues of whether we should do this when we should be about prevention; and does that society have the ability to rehabilitate a patient who may survive but with severe [side effects]?" Rupprecht says. "Jeanna created several ethical issues for all of us to deal with this bug."

Giese says that the fourth-year anniversary of her illness has brought up some bitter memories that she'll probably never shake, but she's glad to be alive—and doing as well as she is.

"It takes some getting used to, but I've kind of come to terms with the fact that I'm the only…[survivor]," she says. "At 15, I never would have thought that anything like this would ever happen, and that I lived is just amazing."

An animal lover who owns a dog, two rabbits and six birds, she hopes to one day open a sanctuary in Fond du Lac for endangered animals, including "big predators like lions and tigers and wolves," and maybe even bats, too.

"I'm not scared of them at all," Giese says of bats. "I'm more passionate about animals than I was before. Animals are my happiness and reason for living."

THE MILWAUKEE PROTOCOL*


How to cite this article:
Agarwal AK. The 'Milwaukee protocol' (MP) hope does not succeeds for rabies victim. Med J DY Patil Univ 2017;10:184-6


Introduction

The Milwaukee protocol (MP), a procedure reported to prevent death after the onset of rabies symptoms, has been performed over 26 times since its inception in 2004 but has only saved one life. Overwhelming failure has lead health officials to label the protocol, a red herring.[1],[2]

Rabies is caused by the rabies virus, an RNA-based virus in the genus Lyssavirus. Transmission typically occurs when virus-laden saliva from a rabid animal enters a wound or mucous membrane. Infection typically occurs from a rabid animal bite. The virus travels along peripheral nerves until it reaches the brain and salivary glands. A characteristic rabies symptom is aversive behavior toward water or water consumption called hydrophobia. Individuals demonstrating hydrophobia will generally avoid water and resist drinking it. Other symptoms include anxiety, nerve pain, and itching, impaired sensation of touch, convulsions, paralysis, and coma. Cases among unvaccinated individuals almost always result in death.

The MP was conceived in 2004 by a team of medical professionals, led by Dr. Rodney Willoughby, after a 15-year-old girl was admitted to a Milwaukee hospital after a rabies diagnosis. After consulting with researchers at the Centers for Disease Control and Prevention in Atlanta, the team formulated and implemented a novel procedure. The patient was placed in a drug-induced coma and given an antiviral cocktail composed of ketamine, ribavirin, and amantadine. Considering the theory that rabies pathology stems from central nervous system neurotransmitter dysfunction, doctors hypothesized suppressed brain activity would minimize damage while the patient's immune system developed an adequate response.[3],[4]

The patient was discharged from the hospital 76 days after admission. She demonstrated speech impediment and difficulty walking during a clinic visit of 131 days after discharge. It is unclear how long those conditions persisted. In subsequent years, the patient attended college. She remains the only MP success.[4]

There has been confusion regarding the efficacy of the MP.[1]

Case Report

We report the treatment of a child with rabies, who received the timeliest and complete application of the original MP to date, and compare this case with other MP attempts, discussing implications for advancement in the field.

In Jan 2016, a 10 year-old male from the Morena, India, presented to the Intensive Emergency Unit (IEU) of our J.A. Group of Hospital, Gwalior, 30 km far from Morena, with symptoms suggestive of furious rabies. Six months earlier, the patient had been bitten by a dog in the Morena, and did not receive rabies vaccine or other postexposure prophylaxis (PEP); clinical presentation had been reported with sore throat, fever, and fatigue followed by progressive shortness of breath, dysphasia, and insomnia. In the IEU, he developed irregular mouth movements, visual hallucinations, agitation, aerophobia, and hypersalivation on the 2nd day. Marked heart rate and blood pressure variability were compatible with severe dysautonomia. He was intubated for airway protection. Following thiopental for sedation, he became severely bradycardic, requiring brief cardiopulmonary resuscitation. Neuromuscular blockade was administered because of pharyngeal and diaphragmatic spasms. Coma was induced with ketamine and midazolam infusions as recommended in the MP (version 1.1)[1] for presumed rabies.

. . . .   Conclusion          
Top

As one of the oldest and deadliest infectious diseases, rabies is long overdue for the development of a successful treatment. Six years ago, when the first rabies survivor (without PEP) was described, there was new hope for rabies victims. Unfortunately, subsequent cases illustrate the uncertainties surrounding rabies management and the tremendous resources expended in aggressive supportive care.[8] This case, when taken together with other MP cases to date, suggests that an early immune response may be better correlated with survival, the efficacy of MP antiviral activity is unclear, and ribavirin itself may be immunosuppressive. Aggressive supportive care has resulted in longer survival times and consequently a wealth of clinical and laboratory data, helping to better understand the natural history of rabies and develop specific questions regarding its pathophysiology. Animal models are urgently needed to address these questions, which may ultimately lead to successful outcomes in rabies.

In conclusion, the MP is not an ideal treatment. The low success rate, high costs, and ethical issues surrounding it make it unlikely to ever be extensively used or accepted as an effective treatment. Moreover, new developments to better diagnosis techniques and cheaper vaccines may make rabies a disease of the past.

THIS WIKIPEDIA PIECE REFERS TO A KNOWN 14 HUMANS WHO DID SURVIVE RABIES AFTER DEVELOPING SYMPTOMS. IT DOESN’T MENTION THE MILWAUKEE PROCEDURE.

Rabies
From Wikipedia, the free encyclopedia

Rabies is a viral disease that causes inflammation of the brain in humans and other mammals.[1] Early symptoms can include fever and tingling at the site of exposure.[1] These symptoms are followed by one or more of the following symptoms: violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness.[1] Once symptoms appear, the result is nearly always death.[1] The time period between contracting the disease and the start of symptoms is usually one to three months, but can vary from less than one week to more than one year.[1] The time depends on the distance the virus must travel along peripheral nerves to reach the central nervous system.[5]

Rabies is caused by lyssaviruses, including the rabies virus and Australian bat lyssavirus.[3] It is spread when an infected animal bites or scratches a human or other animal.[1] Saliva from an infected animal can also transmit rabies if the saliva comes into contact with the eyes, mouth, or nose.[1] Globally, dogs are the most common animal involved.[1] In countries where dogs commonly have the disease, more than 99% of rabies cases are the direct result of dog bites.[6] In the Americas, bat bites are the most common source of rabies infections in humans, and less than 5% of cases are from dogs.[1][6] Rodents are very rarely infected with rabies.[6] The disease can be diagnosed only after the start of symptoms.[1]

Animal control and vaccination programs have decreased the risk of rabies from dogs in a number of regions of the world.[1] Immunizing people before they are exposed is recommended for those at high risk, including those who work with bats or who spend prolonged periods in areas of the world where rabies is common.[1] In people who have been exposed to rabies, the rabies vaccine and sometimes rabies immunoglobulin are effective in preventing the disease if the person receives the treatment before the start of rabies symptoms.[1] Washing bites and scratches for 15 minutes with soap and water, povidone-iodine, or detergent may reduce the number of viral particles and may be somewhat effective at preventing transmission.[1][7] As of 2016, only fourteen people had survived a rabies infection after showing symptoms.[8][9][10]

Rabies caused about 17,400 human deaths worldwide in 2015.[4] More than 95% of human deaths from rabies occur in Africa and Asia.[1] About 40% of deaths occur in children under the age of 15.[11] Rabies is present in more than 150 countries and on all continents but Antarctica.[1] More than 3 billion people live in regions of the world where rabies occurs.[1] A number of countries, including Australia and Japan, as well as much of Western Europe, do not have rabies among dogs.[12][13] Many Pacific islands do not have rabies at all.[13] It is classified as a neglected tropical disease.[14]



Duvenhage lyssavirus
From Wikipedia, the free encyclopedia

Duvenhage lyssavirus (DUVV) is a member of the genus Lyssavirus, which also contains the rabies virus. The virus was discovered in 1970, when a South African farmer (after whom the virus is named) died of a rabies-like encephalitic illness, after being bitten by a bat.[2] In 2006, Duvenhage virus killed a second person, when a man was scratched by a bat in North West Province, South Africa, 80 km from the 1970 infection.[3] He developed a rabies-like illness 27 days after the bat encounter, and died 14 days after the onset of illness. A 34-year-old woman who died in Amsterdam on December 8, 2007 was the third recorded fatality. She had been scratched on the nose by a small bat while travelling through Kenya in October 2007, and was admitted to hospital four weeks later with rabies-like symptoms.[4]

Microbats are believed to be the natural reservoir of Duvenhage virus. It has been isolated twice from insectivorous bats, in 1981 from Miniopterus schreibersi, and in 1986 from Nycteris thebaica,[3] and the virus is closely related to another bat-associated lyssavirus endemic to Africa, Lagos bat lyssavirus.

Origin of the Spanish flu pandemic

John M. Barry, Distinguished Visiting Scholar, the Center for Bioenvironmental Research of Tulane and Xavier Universities, New Orleans, Louisiana, concluded that Haskell County was the location of the first outbreak of the 1918 flu pandemic (nicknamed "Spanish flu"), which killed between 21 and 100 million people.[4] Dr. Loring Miner, a Haskell County doctor, warned the editors of Public Health Reports of the U.S. Public Health Service about the new and more deadly variant of the virus. It produced the common influenza symptoms with a new intensity: "violent headache and body aches, high fever, non-productive cough. . . . This was violent, rapid in its progress through the body, and sometimes lethal. This influenza killed. Soon dozens of patients—the strongest, the healthiest, the most robust people in the county—were being struck down as suddenly as if they had been shot." [5] Barry writes that in the first six months of 1918, Miner's warning of "the influenza of a severe type" was the only reference in that journal to influenza anywhere in the world.[6]

Haskell County, Kansas, is the first recorded instance anywhere in the world of an outbreak of influenza so unusual that a physician warned public health officials. It remains the first recorded instance suggesting that a new virus was adapting, violently, to man.

If the virus did not originate in Haskell, there is no good explanation for how it arrived there. There were no other known outbreaks anywhere in the United States from which someone could have carried the disease to Haskell and no suggestions of influenza outbreaks in either newspapers or reflected in vital statistics anywhere else in the region. And unlike the 1916 outbreak in France, one can trace with perfect definiteness the route of the virus from Haskell to the outside world.[7]

Miner's report was not published until April 1918 and it failed to collect the attention it needed. It was not until after 2000 that historians' research revealed the origin of one of the deadliest epidemics in human history.

Historians have generally reported that the path of the disease from Haskell to the world occurred when newly inducted soldiers from the county traveled 200 miles from the county to Camp Funston (now Fort Riley) and were then deployed to Europe at the beginning of United States involvement in World War I.[7]

How Boston Reacted To The 1918 Flu Pandemic

It was late September in 1918 when a doctor at what was then Camp Devens in Ayer summed up the new disease that was killing thousands.

"Two hours after admission they have the mahogany spots over the cheek bones, and a few hours later you can begin to see the cyanosis extending from their ears and spreading all over the face," the doctor said. "It is only a matter of a few hours then until death comes, and it is simply a struggle for air until they suffocate. It is horrible."

Devens was not the first place to see an influenza outbreak that year, but it was one of the hardest hit. It's estimated about a third of people at the camp came down with the flu — a little more than 15,000. Of those, more than 800 died.

"That happening really overwhelmed the hospital here," said Kara Fossey, the executive director of the Fort Devens Museum. "They pulled in some nurses in from other places. There were some nurses and doctors that died here as well. They had to use barracks for makeshift morgues to even deal with all the people."

What was happening in Devens — where the Army surgeon general observed bodies "stacked about the morgue like cordwood" — was a snapshot of what was happening at the same time in Boston.

There, the virus appears to have started among sailors at Commonwealth Pier in late August. And it spread quickly. On September 6, 1918, the Boston Daily Globe reported that there were 300 cases of the flu at Commonwealth Pier.

Four days later, the number had risen to 1,100, prompting this warning: "Boston health authorities who are combating the grippe ask the cooperation of girls who have sailor friends, requesting them to refrain from kissing."

On September 23, the Globe noted that all hospitals were "taxed to their limits." Two days later, Boston Public Schools were shut down and the emergency health committee banned all public gatherings.

In the days that followed, the city health commissioner ordered all places of amusement closed, the sheriff quarantined the Charles Street Jail and the governor made a desperate call for more health care workers.

"I most strongly urge that the public authorities release nurses engaged in work not at this time pressing and that householders dispense with all non-emergency service so that additional nurses may be available for the more serious cases of influenza," read a proclamation by the governor at the time, signed by the lieutenant governor and future president, Calvin Coolidge.

"It is earnestly requested that everyone who has had medical or nursing experience or who can assist in any way communicate with the Commissioner of Health at the State House," the proclamation continued.

The worst of the epidemic lasted for about four weeks. In that time, there were multiple days with more than 150 dead from flu or pneumonia. It wasn't until the number of deaths in Boston dipped below 100 for the second time in three days that the mayor allows bars and theaters to reopen.

The current coronavirus outbreak has not created the same sorts of conditions the 1918 flu pandemic did in Boston.

But Alex Navarro, the assistant director of the University of Michigan's Center for the History of Medicine said there is good reason to look back at 1918.

"It was a global pandemic," Navarro said. "It was one of incredibly high death toll, and caseload, and one also in the quote-unquote, modern era."

Navarro, whose research looked at the flu outbreak in dozens of American cities, including Boston, said the most effective tools governments were able to use were those that isolated the sick and prevented infection — like Boston's ban on public gatherings.

"Timing is really key," he said. "Our study found that association between cities that acted early, that kept many different non pharmaceutical intervention and social distancing measures in place, and that kept them in place for longer fared better."

In other words, telling people to stay home or avoid people who are sick works.

But, he acknowledged, that's not always possible — especially for public leaders who face a skeptical public that might want restrictions to end. Indeed, Navarro said that was the case in some cities that saw a second wave of influenza after lifting bans too early.

"So as a historian, I can tell you that the data suggests that they work, but as a public health official having to make these decisions, they're in a really difficult spot," he said.

It's estimated the 1918 flu killed about 2.5% of those infected. We still don't know how deadly the new coronavirus really is. Germany has reported just two deaths out of more than a thousand cases. South Korea's case fatality rate is about 0.7%.

But in Italy, the death rate has been closer to 6%.

"We don't want to be alarmist and we don't want to say the sky is falling,” said Navarro. “But if you look at the data we have so far, we have a disease that has about the same transmissibility rate as influenza and has a case fatality ratio that is probably on par with what the 1918 epidemic was."
