So hospitals pushed back on CDC communication re transmission because of their N95 supply issues?

I don't know what happened in the CDC. But I keep hearing these fights within hospitals about what these guidelines touch: droplet versus airborne precautions, which is different than what the guidelines mean for the public.

I respect your opinion, but the implications of this suspicion based on “hearing fights” are serious, IMO, and could reverberate. Also, I think the focus on N95s may be a bit misguided. Is there evidence that they are more protective than surgical masks in non-AGP settings?

Those are good questions to investigate! Early on, much of the public health community was telling us only N95s were good enough, and anything else was probably a waste of time. I'm definitely hearing a lot of tensions but you are right that I'm not making a claim about the CDC.

There was a great study in Norway with providers showing no exposures among HCW with basic PPE. And I am seriously hopeful that it was enough as it has all that I have had access to...and same as partner...with in person care since March :)

There was also this study of COVID among HCWs in 3 hospitals in the Netherlands during March. They used surgical masks (N95s during AGPs). No COVID unit HCWs infected during the study period. https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(20)30527-2/fulltext …

“Although direct transmission in the hospitals cannot be ruled out, our data do not support widespread nosocomial transmission as the source of infection in patients or health-care workers.”

Yes, that's encouraging. But also check this study. https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(20)30164-X/fulltext … Go to supplementary texts, and look at table 5. UK HCW are faring really poorly in comparison to US, and as far as I know, their buildings tend to be older, less engineering/air-exchange controls.

The kind of coughing/aerosol study we're seeing now? Should have had it so much earlier. I think you're right that US has encouraging data; but that it is not conclusive given the (appropriate) mitigation layers. Can't go into a pandemic on autopilot: not aerosol, no masks etc.

Infection prevention in hospitals is multifaceted-testing/isolating, universal masking (source control), physical distancing (eg breakrooms), engineering...Type of mask gets a lot of attention but I think this needs to be studied more & could provide insight re transmission ?s.

Agree, that's what I was saying that it is often multi-layered. Also, see this study. https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciaa1270/5898577 … (nursing home; masks worn; outbreak in poorly-ventilated area)
