Also important, by @DKThomp. Some activities are worse than others: talking, singing, huffing and puffing. We should learn from countries that have guidelines for indoors (library rules: keep it low!)https://www.theatlantic.com/ideas/archive/2020/08/wear-your-mask-and-stop-talking/615796/ …

No masks indoors but on playgrounds?
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. https://twitter.com/reneritchie/status/1313103214963838978 …This Tweet is unavailable.Show this thread -
This is WHO's page for the public. It has many paragraphs on the use of hand-sanitizers but doesn't say *even once* that ventilation is important or outdoors is safer than indoors. WHO guidelines maintain the fiction that mere three feet is enough indoors. https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public …pic.twitter.com/gBkU5Ihva7

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 …

Agreed. The same applies to guests at Rose Garden event that were told it was safe b/c everyone tested negative. Details here:https://twitter.com/DiseaseEcology/status/1312537935892246528 …

He’s certainly sending a clear political message there about which party is the pro-COVID party....

Let's wait for the (hopefully quick) update, as trust is key to public health. It's already late!
