The Centers for Disease Control and Prevention revised its coronavirus guidance Monday, acknowledging that it can sometimes spread through airborne particles that can “linger in the air for minutes to hours” and among people who are more than six feet apart.
The CDC cited published reports that demonstrated “limited, uncommon circumstances where people with COVID-19 infected others who were more than 6 feet away or shortly after the COVID-19-positive person left an area.”
“In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise,” the CDC said in a statement. “Such environments and activities may contribute to the buildup of virus-carrying particles.”
The agency added that it is “much more common” for the virus to spread through larger respiratory droplets that are produced when somebody coughs, sneezes, sings, talks, or breathes. People are infected through such droplets mostly when they are in close contact with an infected person, the CDC said.
“CDC’s recommendations remain the same based on existing science and after a thorough technical review of the guidance,” the agency said. “People can protect themselves from the virus that causes COVID-19 by staying at least 6 feet away from others, wearing a mask that covers their nose and mouth, washing their hands frequently, cleaning touched surfaces often and staying home when sick.”
The updated guidance comes after the agency mistakenly posted a revision last month that said the virus could spread through aerosols, small droplets that can linger in the air. The guidance was quickly removed from the CDC’s website because it was just “a draft version of proposed changes,” the agency said.
To what degree the coronavirus can spread through airborne particles has been a contentious debate among scientists for months. Some epidemiologists have charged that the World Health Organization as well as federal regulatory agencies in many countries have been slow to accept that the virus can spread by air. It’s a debate that could have implications for the importance of air filtration in reopening businesses and schools.
现在还赖土共掩盖疫情的该歇歇了，美帝现在还改来改去，没个准信，真是作孽。

CDC在这次疫情中就是个JOKE
这事中国一月底就公布过了吧。
just “a draft version of proposed changes,”？？
太不要脸了，哈哈
faa后又一个牌坊倒了。
整个美国不就是笑话吗？
感染的人最多，死的人最多。医疗缺乏，物资缺乏，大批病人无法得到必要的治疗。妥妥的世界第一伪强国。
