It is curious why the CDC has never recommended better quality masks despite wide availability now (I had quality masks in March of 2020 but hey bf wanted protection from the awful smoke of west coast climate fires so had N95s then by coincidence). Why the CDC doesn't stress ventilation. And why what is actually a norm in many countries is to self-test yourself before all social events is kind of unheard of here. But that will never be a norm for most if test kits are near $30 and hard to find of course.
