My mistake, here is what the WHO said: > "If you do not have any respiratory symptoms...you do not need to wear a medical mask" Which is somehow worse.

I've yet to see any actual evidence that wearing a cloth mask while social distancing helps you, as a healthy individual. And I've seen some to the contrary[0]. One of the WHO's main concerns is to prevent shortages and supply chain issues (see their statements about travel and import bans). A run on medical masks is problematic, and the WHO's guidance prevents that. I'll note that basically no government suggested (or suggests) wearing medical masks[1], unless you are symptomatic, which is in line with the WHO's guidance. Social distancing is much more important, and while masks may help, especially in areas that are crowded (which you should avoid if possible anyway), they only really help if you are symptomatic, in which case you should absolutely not be outside. The bay area is fairly unique in requiring mask wearing, and while it's not a major imposition, the utility is probably pretty marginal.

In countries where masks were mandated, there was simultaneously lock on medical masks. People used homemade ones at first and then later you could buy non-medical cloth masks. > they only really help if you are symptomatic This does not make sense either. You spread virus before having symptoms. Asymptomatic people spread virus too.

People used homemade ones at first and then later you could buy non-medical cloth masks. Right, and there are no studies that I'm aware of showing that cloth face masks are effective at stopping the spread of covid-19. They're good at stopping large particles (which afaik you only really have if you're coughing), but not small/aerosolized ones. Again, if you're being careful with your mask and making sure to clean it regularly and treat it like a dangerous object and washing hands after using it etc. It might help. If you aren't, it might hurt. Hence the WHO's guidance. To be clear, I'm not saying "masks are bad", or even "masks aren't good". I'm saying "the evidence that masks are helpful is not strong enough to decry an organization that doesn't recommend them."

      > which afaik you only really have if you're coughing Which is something people do. The general advice is changing last weeks, it is more and more recommended to wear them even in countries that were super opposed a month ago. You dont need mask to be 100% effective to be useful.
