Merged 2019-nCoV / Corona virus

[Capsid]

There's no question this virus jumped from animal to people. And jumping from one animal species to another as an intermediary before jumping to humans is very common.

It could also be that the first people infected, infected others at the market, or infected animals at the market that then infected more people.

I was just pointing out the market is no longer thought to be where patient zero acquired the infection.

It's uncommon for viruses to cross the phyla. Usually, mammal viruses infect mammals.

Thanks. I knew that really.

Interesting. It would appear we need to drop the snake connection altogether unless some better evidence than a possible correlation turns up.

CDC: Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats.

Livescience: He added that there is no solid evidence that coronaviruses can infect hosts other than mammals and birds. Brandão is currently investigating whether coronaviruses can infect snakes.

I would expect patient zero to be an animal collector (hunter) or an animal middleman or an animal retailer, but not the end-person buying the animal for consumption.

I would expect we will never know. This virus is too stealthy for that.

Why? What do you base that on?

So now I want to know if bats were in season back on November 9th or if they were already hibernating and unavailable even to the bat hunters.

I think you underestimate how far the science has come.

From the CDC link:

Chinese health authorities were the first to post the full genome of the 2019-nCoV in GenBankexternal icon, the NIH genetic sequence database, and in the Global Initiative on Sharing All Influenza Data (GISAIDexternal icon) portal, an action which has facilitated detection of this virus. CDC is posting the full genome of the 2019-nCoV viruses detected in U.S. patients to GenBank as sequencing is completed.

2019-nCoV is a betacoronavirus, like MERS and SARs, all of which have their origins in bats. The sequences from U.S. patients are similar to the one that China initially posted, suggesting a likely single, recent emergence of this virus from an animal reservoir.

The animal collector is the guy who grabs it from the wild. He hunts the caves and forests to snatch bats and maybe snakes too.

I don't think I do. I just don't understand how sequencing the genome will help in tracing the first human patient, who might have not showed any symptoms. If the virus induced severe, unmistakable symptoms in every human, it would be possible. But we know this virus does not.

 

[Dr.Sid]

New data about how the virus can spread asymptomatically:

The "genetic clock" allows researchers to pinpoint when patient zero happened, but not who. Further research might be able to determine who but maybe not.

That would require sequencing of virus from every patient. While possible, is finding the first patient so important ?

Maybe they come to learn that the only guy collecting bats from a cave on November 9th is a dude named Dr. Sid Guano. They'd like to meet with him but he died on November 16th.

You don't think people come in contact with bats where they live?

That's not how it works. Sampling is sufficient.

 

[William Parcher]

Not typically unless they live in bat caves.

China and a few other countries are unusual because they collect and eat bats.

Bats live around people. Sometimes they roost in buildings.

But there's good news: According to US Commerce Secretary Wilbur Ross the virus will be good for the US economy.

And in Italy, "Oriental" students who haven't been home in years are being kept out of class.

After all, all those chinks are not really human.....
Aside from the sheer heartlessness of it, it's stupid from an economic point of view. If the VIrus manages to do severe damage to the Chinese Economy, it will do severe damage to the World Economy, which will do damage to the US economy.
