Yeah, we're flying a little blind here. The problem is the interaction between that ship which has sailed, tragically, and the people who need to think about self-protection in this environment.
In the end im an empiricist. If someone is particularly vulnerable & in high exposure setting of course perfectly reasonable to upgrade if they wish, tho still seems to me simple guideline of 1 surgical mask most justifiable, esp w comfort/fit issues

I agree for hospital setting! But there, you have aggressive ventilation standards plus universal masking. The question is often coming from individuals who are forced to interact with people who don’t mask or do badly, and in poorly ventilated areas. PPE, not source control.

So that’s exactly the point! These people need some guidance. So we are in agreement. Hospitals are doing great. Universal masking of patients with surgical masks plus good ventilation works. But high-risk folks/situations in community are looking for self-protection.https://twitter.com/AaronRichterman/status/1354652892075077632 …

I question the selection of a photo that depicts a valved mask, which poses a vastly more real and pronounced risk than an imperfectly fit-tested use of an N95 respirator. Visual messaging is messaging, even to a supposedly enlightened audience.
