I honestly didn’t know coronavirus was a thing for humans. I know about the strain that affects cats (85% have come into contact with it, I believe). I also didn’t know it could be dangerous.
The common cold is caused by a few different viruses, mostly rhinoviruses, but one coronavirus does cause common colds.
SARS and MERS are coronaviruses that recently became well know when they emerged to start infecting humans from their formerly preferred host species (civet cats for SARS, and camels for MERS).
I believe I read that this new coronavirus is only the seventh known to infect humans, most remain restricted to animal reservoirs like bats and camels.
This new one is supposed to be genetically most-closely related to SARS. But I don't see anything in the current numbers to suggest that the fatality rate is even close to that of SARS.
I also don't think the papers are correct in saying that 1.4 billion Chinese people will be traveling abroad for Lunar New Year...that would leave China completely devoid of people for the duration of the holiday!
I think they're doing the right thing to be being cautious with it. It's possible that people in/around China have been exposed to this virus before and it's not the first time its leapt into humans, so they might have historical resistance to it over there, and maybe people outside China could be hit harder by it. But those numbers don't look as severe as SARS to me. And from the few stories of those who've died from pneumonia caused by this new coronavirus, they had severe pre-existing conditions that would have left them more susceptible to a severe case of pneumonia. That happens with any flu or pneumonia, but we live with those all the time.
I am very interested in the tracking and learning about a new disease like this, but I absolutely do not support any fear-mongering press about it. Remember with Ebola, it was devastating to some parts of the countries where the disease originated, but in countries like the US and UK, more people died in a single day from traffic accidents, heart disease, and cancers, than died in total outside Africa from Ebola. And the more severe this turns out to be, the harder various medical and governmental organizations will work to try and prevent its spread. If most cases are relatively mild, though, it's possible that it will spread across the world and there's nothing anyone can do about it, just like the common cold and regular flu.
