Does that say it's harmful to wear masks? The WHO's guidance has been that it isn't necessary for individuals to wear medical PPE. There are valid concerns about this, both related to shortages and improper care.
Yes, it does. "In fact, there's some evidence to suggest the opposite". But that is irrelevant, since that is not what I claimed. I said the WHO says masks don't work. I quoted them saying it to CNN for you, and linked it. How much more in denial can you get?
>The WHO's guidance has been that it isn't necessary for individuals to wear medical PPE
I just showed you their guidance, which says they will not help. The overwhelming evidence unanimously says that it does help.
>There are valid concerns about this, both related to shortages and improper care.
There are not. There is no shortage of cotton fabric. Improper use of masks is still superior to no masks.
There's conjecture, and maybe some empirical evidence about cloth masks, but it's weak.
