Federally funded tests conducted by scientists from several major institutions indicated that the novel form of coronavirus behind a worldwide outbreak can survive in the air for several hours. A study awaiting peer review from scientists at Princeton University, the University of California-Los Angeles and the National Institutes of Health (NIH) posted online Wednesday indicated that the COVID-19 virus could remain viable in the air "up to 3 hours post aerosolization," while remaining alive on plastic and other surfaces for up to three days. "Our results indicate that aerosol and fomite transmission of HCoV-19 is plausible, as the virus can remain viable in aerosols for multiple hours and on surfaces up to days," reads the study's abstract.

其实不管是阳性阴性，这时都会宣布阴性的。懂的人自然明白，不懂的人可以振奋人心。
因为你自己说的话就可以反驳你，你当然觉得奇怪呀
你说中国是因为一起大家吃饭才传染的很厉害的，不就是承认唾液传染么，带口罩可以防止唾液飞沫了，怎么会没有用呢
