CDC? WHO? We still don’t have ventilation integrated into our guidelines. People are being told to wash their hands, but not open their windows. It’s September 2020.https://twitter.com/adamhamdy/status/1304120806943928329 …

We need to be able to trust the CDC and the WHO to lead, to give us the best of research and public health guidelines. It's October 2020. I know there are people in both organizations who spent their lives for public health. But please. If not now, when? This is catastrophic.

I WANT TO support the WHO. But this is their *current* mask guidelines. It says that community health workers doing screenings, or the public being screened, do not need to wear masks AT ALL if one meter apart (a mere three feet)—even if indoors. https://www.who.int/publications/i/item/advice-on-the-use-of-masks-in-the-community-during-home-care-and-in-healthcare-settings-in-the-context-of-the-novel-coronavirus-(2019-ncov)-outbreak …pic.twitter.com/sbLRklR7qh

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 is running that place? Things badly need to be fixed over there. I'd vote to put you in charge, Zeynep.

I understand the CDC’s corruption somewhat, but why is the WHO so corrupted on the issue of ventillation?
-
I don’t believe it’s corruption, they just are set in the mind to reject aerosols until there is scientific proof of their danger The mountain of circumstantial evidence isn’t considered sufficient to update guidance

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.
