re: WHO: Masks should only be worn by healthy people when caring for covid patients

I'm not sure I've ever seen something like this. Sure, dietary stuff changes, but over decades.

World-renowned medical outfits have repeatedly flip flopped on the mask wearing, and frequently it's premised on stuff like "could provide a false sense of security."

At least with hydrochloroquine it's a mixture of political motivations and conflicting studies/surveys that keep coming out. The back and forth we see on masks appears to be almost entirely arbitrary.
