The Coronavirus outbreak in China had a high morbidity but very low mortality ( around 2-3%). The infection may be fatal in persons who are suffering from cancer, diabetes, chronic respiratory disease, cardiac illness ,HIV/AIDS etc.

Thank you Mahendra Pal For your answer And thoughts, Appreciated .

Thank you Mohammed Ali Bait Ali Sulaiman for your answer. Appreciated .

It depends:

1. Older people have higher death rate

2. People with underling medical issues have higher death rate

3. Men have higher death rate than women with the disease

4. Which countries the patient is in (for now), in some countries the death rate is higher than the others

This virus has been officially down graded but we are not being told...

It would seem from the figures that have been quoted that the overall worldwide figures based on those infected that 0.016% fatality so far much less than the flu

The USA already know what the implications of the virus going to be, because in May 2018, the John Hopkins Center for Health Security ran a simulation called "Parainfluenza Clade X" to determine what the potential would be of a virus pandemic, and they concluded: "...twenty months 150 million people worldwide--two percent of the global population--have died."

"...The global economy has collapsed under the strain, with the Dow Jones average down 90 percent. U.S. GDP down 50 percent, and unemployment at 20 percent. Washington is barely functioning--the president and vice president are both ill, one one-third of Congress is dead or incapacitated."

People involved in that simulation were Tom Daschle (former leader of US Senate), Dr. Julie Gerberding (former head CDC), Jim Talen (former Missouri senator)--Why are all of these people keeping quiet right now, and not telling us what they saw in the global virus pandemic simulation only two years ago, and helping lead us out of this mess, with some new simulations???!!!

This simulation information is from pages 201-203 of the Bryan Walsh book, "END, A Brief Guide to the End of the World: Asteroids, Supervolcanoes, Rogue Robots, and more", published in 2019. The author also predicts on pages 192-194 the various reasons why, he believes that Trump "lacks the talent and the temperament to lead the United States through an outbreak..." plus, "...there are aspects about Trump that .."make him dangerous in the face of a new disease."

Detail about the John Hopkins "CLADE X" exercise can be read at

The availability of healthcare in general and specifically critical care will affect case fatality. In China and Italy where large numbers of healthcare professionals were infected the capacity to deliver healthcare was substantially reduced.

Another important factor to consider when trying to interpret variation in mortality rates between countries is differences in cultural interpretation of quality of life. This impacts the social and medical ethics and the delivery, limitation and withdrawal of life sustaining therapies.

In many Western cultures quality of life is valued far more than quantity of life. In those setting limitation and even withdrawal of life sustaining therapies are a common mode of death.

In many Eastern cultures quantity of life is valued more than quality of life. In these settings treatment limitations and withdrawals of therapy are rare. Admission to intensive therapy units and prolonged organ support are common. Mode of death is often cardiac arrest.

These differences are magnified when there are limited resources particularly in Western countries. The social and medical acceptance of treatment limitations is increased; this may significantly increase case fatality rates.

An interesting adverse effect of social isolation for the Covid-19 pandemic has arisen. There has been a dramatic fall in the number of blood donors in Saudi Arabia a result of social isolation during the Covid-19 Pandemic. Supplies of blood are being depleted. This is likely to be a global phenomenon

Patients may die as a result of not being transfused blood severe acute bleeding due to stress ulceration, for example. If the patient has severe or critical Covid-19, the cause of death is actually the Covid-19 but it is likely to be coded as GI tract bleeding.

Lies, damned lies and statistics as Disraeli said. It will be impossible to unpick the true effect of Covid-19 on patient outcomes.

GOOD NEWS from California and the USA on April 2! The days to doubling of total cases is lengthening. In California our total case numbers were doubling like clockwork, every 3-4 days between March 8 and March 29th.

We put on "Lockdown Lite" on the 16th. Then from March 30 to today, the numbers are now doubling every 12 days. Once every country ON THE PLANET goes on a severe-enough lockdown for at least a month, then the total number of cases and days to double, start stretching out after 2 weeks of Lockdown.

There is a good chance of NOT Dying from the virus, if your country institutes the Lockdown immediately, instead of like the USA whose president unfortunately had a chronic infection of "Denier-Disease" whose symptoms are: "a person who refuses to accept the existence, truth, or validity of something despite scientific evidence."

Yesterday, President Trump was still refusing to do any lockdowns in any of the Republican states that support him, which means that a lot of his supporters will be too sick or dead, to be able to vote in November?

To control the Covid-19 pandemic effectively and minimise the risk of death, healthcare professionals and the public must hear and accept difficult truths. America has failed to do this; so the virus spreads unchecked.

Transmission of the virus can not be stopped it can only be delayed to allow healthcare systems to cope with the increased demand on services. So please preserve respirator face masks for healthcare professionals who must care for patients infected with SARS-CoV-2.

Unfortunately, rather than being honest; authorities have repeatedly changed advice about the need to wear facemasks. As a result, healthcare professionals and the public can no longer trust what is being said. The mistrust has been fuelled by conflicting messages for healthcare professionals and the general public.

In the current situation the only safe thing for anyone to do is to try to wear facemasks that provide the best protection. The real difficulty is that the best medical grade respirator face masks are in extremely short supply. Healthcare professionals, putting their lives on the line, need these masks to protect themselves from their infected patients.

Up to 25% of healthcare professionals in the UK are either off work due to sickness or because of suspected exposure. Excess deaths occur when healthcare systems can not care for patients who need treatment. The more healthcare workers who go off sick, the less care sick patients can receive.

The public can be protected by social distancing. As an intensivist I do not have this option, I must get very near to patients to look after them. I will be honest; respirator face masks do protect people from transmission of Covid-19. Cloth face masks are unlikely to protect uninfected people but are likely to reduce spread of virus from those infected with SARS-CoV-2. Not going near patients with Covid-19 is more effective. I therefore ask the public to fully engage with social distancing and preserve the medical grade face masks for healthcare professionals who do not have this option.

April 5 - In California, after only 2-1/2 weeks of "Lockdown Lite" which means you can still travel from State to State or from County to County, the biggest issues are lack of income and restlessness.

Because others like to buy our US Treasury bonds, and $24 Trillion in debt, we are about to vacuum out a couple of more trillion from the rest of the world to save ourselves, to pay our workers while they are on lockdown for a month or two. How is each country going to keep paying their workers while on lockdown?

Then, there is restlessness?We are billions of primates, who over the last 5,000 years, have become used to living in hive-like colonies--going to and fro on a daily basis, and interacting with dozens of non-family members each day. That is the glue that keeps our hive structures intact on an hour-to-hour and day-by-day basis.

Agreements that you have with everyone around you,that keeps the hive functioning week-to-week and month-by-month, that the stores will have food on the shelves, and the farm workers will be out picking the produce you need to live, and the electricity will keep flowing through the wires?

Plus, even the ex-situ "interactions"where the individuals participate as observers, must also cease, like the sports events, concerts, wars, and battles—while we are locked in our own little family-unit-worlds for a couple of months?

Will that hive-structure start breaking down, when the interactions must cease for months, or will individuals get restless, and resume contact too soon, like Trump wants us to, and keep spreading the virus that way?

What to do if you get Covid-19.

These recommendations apply to young adults with no medical conditions. If you have medical conditions or any concerns it is best to speak to your doctor for specific advice. This is particularly important if you have a pre-existing lung condition or are taking immunosuppressant medications.

Prepare for a nasty chest infection.

Things you have to hand

• face tissues,

• Acetaminophen; for a fever over 38°c, take acetaminophen rather than Ibuprofen.

• Generic, cough medicine to thin mucus (check the label make sure that it does not contain paracetamol; otherwise you could double dose and get side effects)

• vaporub for your chest is also a great suggestion.

• humidifier would be useful; however, turning on a hot shower and breathing in the steam in the bathroom may also help.

• Food: soups are ideal

• Drink: stay well hydrated, water is fine

Prevent transmission

• Rest and do not leave your house. You could be infectious for fourteen days.

Avoid elderly people and those with pre-existing health conditions.

• Wear gloves and a mask to avoid transmitting the infection

• If you do not live alone. Isolate yourself in your bedroom. Ask those you live with to leave things outside to avoid contact.

• Wash your bed linen and clothes frequently. sanitise your bathroom.

The vast majority of Covid-19 cases in healthy adults can manage at home with rest, hydration, acetaminophen, cough medicine.

Go to hospital if you are having trouble breathing or your fever is very high (over 39°C) and not settling with acetaminophen and cooling with ice packs or if you are worried, in distress or feel your symptoms are getting worse.

If you have any medical conditions please seek specialist advice from your doctor.

Thank you all for your contribution. Appreciated.

Although the virus has a high potential to spread, it does not have a high rate of killing if the infected person is attended to medically. Therefore, the chances of dying is low and this can be seen in the number of people that have so far recovered in different countries of the world.

The person who are old, or suffering from respiratory, cardiac problems or immunocompromised may have more chances of fatality.

PARTICLES and the virus--We are discovering here in California, that the virus can "hitch hike" on particles. When someone breathes, or coughs or sneezes, the rule is keep two meters apart. But that seems to only work in clean air, with no smog or smoke particles, or tobacco smoke, or salt spray particles if you are at the beach.

A smoker could be like a long distance virus spreader, the virus riding perhaps for hundreds of meters carried on that smoker, since tobacco smoke as it comes from a cigarette is an extremely concentrated aerosol with a relatively stable distribution of sizes ranging from 0.1 to 1.0 micron, peaked between 0.2 and 0.25 micron. So not only can you breath in the virus, but it could get deep into your lungs that way.

Maybe this is a good time for the human race to stop smoking tobacco?

For the California County of Santa Clara, about 2 million people, the location of most of "Silicon Valley" the results of the pandemic:

--First case Jan. 21.

--By March 6, 24 cases, and this date starts the days to doubling tracking--

--March 9, only 3 days to double total cases.

--March 14, five days to double.

--By March 16 when lockdown begins, 135 cases.

--March 20, 6 days to double.

--March 25, 5 days to double.

--March 29, 4 days to double.

--April 8 total cases 1,380

--Predicted next doubling, April 22, with 25 days to double.

1969 song "Somethings in the Air" ..by Thunderclap Neuman says it all:

"Intro : Call out the instigators. Because there's something in the air We've got to get together sooner or later...

[Bridge : Thunderclap Newman] Lock up the streets and houses. Because there's something in the air..."

One way to lower the number of new cases rate, is for everyone to know the coronavirus lifespan on different surfaces--cloth two days, paper money four days, and outside of masks the longest, at 7 days. Paper money might be a major "vector" for transmitting the virus, so perhaps banks should start "laundering" their currency and coins? ?

THIS is the new health order issued today about face coverings, April 17, 2020, in my County in California--- Bay Area health officials... are recommending residents cover their nose and mouth with cloth when leaving home for essential travel such as doctor appointments, grocery shopping or pharmacy visits.

The regional recommendation aligns with new guidance from the California Department of Public Health.

The face coverings do not have to be hospital grade but need to cover the nose and mouth. For example, bandanas, fabric masks and neck gaiters are acceptable. Fabric covers and bandanas can be washed and used again.

Health officials do not recommend that the public use medical masks (N-95 or surgical masks), which are in limited supply and must be preserved for our health care workers and first responders.

Up until now, local officials have not recommended the large-scale use of face coverings, but circumstances have changed.

“In addition to shelter-in-place and social distancing requirements, wearing a mask in public is an important tool to stop the community spread of this disease,” says Scott Morrow, MD, San Mateo County health officer. “People with no or mild symptoms may have coronavirus and not know it. Wearing face coverings helps protect others from exposure.”

Covering the nose and mouth with cloth also may be beneficial as a reminder to keep physical distancing. Health officials continue to stress that staying home, frequent hand washing and physical distancing are the best ways to prevent the spread of COVID-19, the disease caused by the coronavirus.

Acceptable face coverings can be made of a variety of cloth materials, be factory-made or hand-sewn, or can be improvised using bandanas, scarves, t-shirts, sweatshirts or towels.

Face coverings should be washed frequently with detergent and hot water and dried on a hot cycle. Ideally, wash your face covering after each use, and have a dedicated laundry bag or bin.

Make sure the covering is comfortable – you don’t want to have to keep adjusting the mask, which means touching your face.  Always wash your hands, or use hand sanitizer, before AND after touching your face or face coverings.

=========================

If the person has strong immune system, the chances of dying from any infectious disease including COVID-19 is decreased.

As more and more studies are conducted, it seems that mortality, or better the IFR (Infection fatality rate) is something between 0.2% and 0.35%. A collection of over 50 prevalence studies, which is constantly updated, can be viewed here: https://docs.google.com/spreadsheets/d/1zC3kW1sMu0sjnT_vP1sh4zL0tF6fIHbA6fcG5RQdqSc/edit#gid=0

An important bias is perhaps that until now it only includes studies of developed countries, with much older populations.

Check what is happening in each country at https://www.worldometers.info/coronavirus/#countries ... and if you are interested in predicting the future, print out the "Total Cases" linear chart, get a ruler and pen, and continue the trend line forward. Unless, like New Zealand and China--- you do not start severely bending the curve---then the next 3-6 months look like they will still be out of control, for countries like the USA, Brazil, India, and Russian ?
