Weekend update, CDC has finally explicitly acknowledged airborne transmission, and is now highlighting the importance of inhalation as a route, and thus ventilation as mitigation. See thread for interesting science history of how key measures got mangled.https://twitter.com/jljcolorado/status/1307920120203759616 …

YEAY! We finally got the CDC update. Acknowledges airborne transmission, emphasizes ventilation, says six feet not absolute when indoors especially if singing/exercising (add talking). There may be minor quibbles among the scientists but this is important! https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/how-covid-spreads.html …pic.twitter.com/LOmF7PWaBB

Finally, solid guidelines from the CDC. Masks at all times *around others*; indoors/crowds are higher risk; outdoors/good ventilation are better! Aerosol scientists also emphasize that they concentrate *near* the person so distance is important regardless one's underlying theory.pic.twitter.com/PftF07TirO

Yep! This CDC update is not more of the same without impacting guidelines or recommendations. It has *many* important practical implications and changes compared to the one that did not acknowledge airborne transmission. That's why it matters a lot.https://twitter.com/HikerDave57/status/1313190311745654784 …

WHO was more obsessed about controlling social media than doing their job.

Great idea if you want to increase the spread. Why not reuse swabs as well?

This is a crime.
@WHO - shame on you. We will not let this go. You knew covid was#airborne v early on, as evidenced by this FEB 11 vid of@DrTedros stating it emphatically at 41.50. And you know what that means? Your guidance IS WRONG & you know it.https://www.youtube.com/watch?v=edvsh6x_f4Q …Thanks. Twitter will use this to make your timeline better. UndoUndo

Let's wait for the (hopefully quick) update, as trust is key to public health. It's already late!
Failure all around. CDC still hasn't posted guidelines for airborne transmission. WHO's advice to the public still doesn't *mention* ventilation or how 3 feet isn't enough indoors or say masks on at all times indoors.
