"Coronavirus and the US" or "We are all going to die!!!!"

I have a question. Has it been determined that Covid-19 is a "one-and-done," meaning that once you contract the virus and recover, you have immunity thereafter? Or is it more like the regular flu, which mutates all the time and you need an annual immunization? It would seem that the answer to that question would have a great impact on strategies for dealing with the pandemic in the immediate future.

We do not yet have that information.

The "reinfections" we have seen in China appear to be cases where the virus wasn't actually completely cleared. I strongly suspect the real issue was they got out of the hospital and could smoke again.
 
Sounds like we'll be in a situation where someone needs to be tested for the virus, then after they have recovered, get re-tested and possibly re-tested again to make sure they are fully clear before being released into gen-pop.

And this when most areas have a shortage of test kits as it is.

I know. Plus, there are probably so many people walking around who only had very mild symptoms that it seems impossible to keep the virus from spreading unless almost everyone stays home except for going to buy food or have Rx. refilled and things like that.

The extra tests are to make sure that the individual isn't still shedding the virus. But, this is an overwhelming mess without any good solutions.
 
Australian researchers claim two existing drugs could 'cure' COVID-19 after patients they tested responded 'very well' to treatment

Drugs used to treat HIV and malaria could be used to tackle the coronavirus, according to scientists in Australia.

A team of infectious disease experts at the University of Queensland in Brisbane say they have seen two existing medications manage to wipe out COVID-19 infections.

Chloroquine, an anti-malarial drug, and HIV-suppressing combination lopinavir/ritonavir have both reportedly shown promising results in human tests and made the virus 'disappear' in infected patients.

The drugs are being tested as researchers and doctors around the world scramble to try and find a vaccine, cure or treatment for the deadly virus.

Heard that HydroxyChloriquine was even better.
 
They may yet find a miracle cure, but beware of scams and rumors on social media. People are already rushing out to buy products with alleged curative properties.

Chloroquine isn't something that would make a very good basis for a scam. It's been around for a long time.

Protozoan versus virus
 
With the rush on toilet paper and bottled water, I have to wonder if some social media site hasn't claimed that wrapping yourself in toilet paper and soaking it with bottled water (not tap water) is an effective defense against the virus.
 
I was surprised to see a Doctor of Medicine say this. I know he's libertarian, but still....

A physician posted this.:

Feeling confused as to why Covid-19 is a bigger deal than seasonal flu? Here it is in a nutshell. I hope this helps. Feel free to share this to others who don’t understand...

It has to do with RNA sequencing.... i.e. genetics.
Seasonal flu is an “all human virus”. The DNA/RNA chains that make up the virus are recognized by the human immune system. This means that your body has some immunity to it before it comes around each year. You get immunity two ways...through exposure to a virus, or by getting a flu shot.

Novel viruses, come from animals.... the WHO tracks novel viruses in animals, (sometimes for years watching for mutations). Usually these viruses only transfer from animal to animal (pigs in the case of H1N1) (birds in the case of the Spanish flu). But, once one of these animal viruses mutates, and starts to transfer from animals to humans... then it’s a problem, Why? Because we have no natural or acquired immunity... the RNA sequencing of the genes inside the virus isn’t human, and the human immune system doesn’t recognize it so, we can’t fight it off.

Now.... sometimes, the mutation only allows transfer from animal to human, for years it’s only transmission is from an infected animal to a human before it finally mutates so that it can now transfer human to human... once that happens..we have a new contagion phase. And depending on the fashion of this new mutation, thats what decides how contagious, or how deadly it’s gonna be..
H1N1 was deadly....but it did not mutate in a way that was as deadly as the Spanish flu. It’s RNA was slower to mutate and it attacked its host differently, too.

Fast forward.

Now, here comes this Coronavirus... it existed in animals only, for nobody knows how long...but one day, at an animal market, in Wuhan China, in December 2019, it mutated and made the jump from animal to people. At first, only animals could give it to a person... But here is the scary part.... in just TWO WEEKS it mutated again and gained the ability to jump from human to human. Scientists call this quick ability, “slippery”

This Coronavirus, not being in any form a “human” virus (whereas we would all have some natural or acquired immunity) took off like a rocket. And this was because, humans have no known immunity...doctors have no known medicines for it.

And it just so happens that this particular mutated animal virus, changed itself in such a way the way that it causes great damage to human lungs..
.
That’s why Coronavirus is different from seasonal flu, or H1N1 or any other type of influenza.... this one is slippery. And it’s a lung eater...And, it’s already mutated AGAIN, so that we now have two strains to deal with, strain S, and strain L....which makes it twice as hard to develop a vaccine.

We really have no tools in our shed, with this. History has shown that fast and immediate closings of public places has helped in the past pandemics. Philadelphia and Baltimore were reluctant to close events in 1918 and they were the hardest hit in the US during the Spanish Flu.
And let me end by saying....right now it’s hitting older folks harder... but this genome is so slippery...if it mutates again (and it will). Who is to say, what it will do next.

Be smart folks...

#flattenthecurve. Stay home folks.

Moscow University promise cheap vaccine in 3 months.

Moscow has been telling a lot of lies in order to stir up trouble in the west. Why should we think this is not more of the same? 3 months is simply too short for the test cycle, not to mention ramping up production once you have figured out what works.
 
That's a bad explanation, because virus genomes are hidden with the viruses' protein coats. It's the protein coat that an immune system "sees". An immune system needs to able to recognize some target before it can attack that target.

Our immune systems have two main subsystems: an innate immune system and an adaptive immune system. The innate system is the older of the two, and it is shared across most of the animal kingdom. It's easy to find research into the immune systems of fruit flies, for instance. It has some rather obvious limitations. The adaptive immune system is the younger of the two, and it emerged in early jawed vertebrates - early jawed fish. It can recognize something that does not belong, and then attack it. It is a rather complicated system, since it must avoid attacking its owner, and it must avoid an excessive response. Attacking its owner is what causes autoimmune diseases.

It might seem that all we need to fight infectious disease is our immune systems, but infectious organisms can get established well before the immune system can go into action. Our bodies can nevertheless conquer some infections with an immune-system response, and our immune systems can remember what the infections' organisms "look like". An immune response does not require an exact match of surface contents, but too different will mean no response.

Vaccines work by provoking an immune response, and ideally, they cause no disease or a very mild one. They are named after cowpox, also known as vaccinia, a disease that protects against smallpox because the cowpox viruses provoke an immune reaction that also protects against smallpox.

There are several kinds of vaccines: live virus, killed virus, and virus coat. The latter sort of vaccine has been made possible by genetic engineering.
