Here's an Israeli biological weapons analyst pointing out that that the Wuhan Institute of Virology is China's leading virology research center (hosting China's only declared level 4 containment facility), and that it and another laboratory in the city have long been suspected of having ties to China's covert biological weapons research. He admits that there is no clear evidence tying them to the origin of this disease. (They are probably working overtime to study it after it appeared.) https://www.washingtontimes.com/news/2020/jan/24/virus-hit-wuhan-has-two-laboratories-linked-chines/ I think that the probability of the bioweapons connection being true is still low and that it's basically conspiracy-theory stuff. But it's out there on the internet, including the Chinese language internet where people are claiming that this is a version of the SARS virus deliberately bioengineered to make it more deadly, virulent and difficult to treat, and that kind of talk is making people afraid. It's being countered by internet suggestions (seemingly impromptu and not an organized campaign) that it's a US bioweapons attack. China has announced a ban on all foreign travel by Chinese starting Monday. Long distance bus and train lines across China are being shut down. Japan has announced evacuation flights for the 700 or so Japanese in Wuhan. Third confirmed US case in Southern California (an individual recently arrived from Wuhan). At least some of the US evacuation flights from Wuhan are reportedly headed to San Francisco. (I live not far away.) After initially doubting that it could be passed human-to-human, the medical authorities are now saying that people are infectious before they show any symptoms. Physicians in Singapore think that about 20% of those infected will develop severe illness like pneumonia. I still think that the reaction that we are seeing isn't really consistent with this just being effectively a new strain of flu (that happens most years) and no worse than that. (That's the kind of line that the WHO is still putting out.) It's clearly something more and the Chinese government appears to know it. I think that the Chinese public is starting to realize it too. Here's an anonymous individual who claims to be a medical worker in Wuhan who is claiming that far from the not quite 2,000 cases being publicly acknowledged, the true number is more like 90,000. (And that was yesterday.) No idea what the source for that number is. She says that unless they are isolated, each infected person can infect up to 14 other people, so the disease is growing geometrically and spreading explosively. https://twitter.com/Terrence_STR/status/1221100970521829377 https://nypost.com/2020/01/26/coronavirus-whistleblower-nurse-says-china-has-90000-sick/ Once again, it's more unofficial social media stuff. But when the conventional government-controlled media isn't considered trustworthy, that's all people have. So rumors proliferate, probably not all of them true.
