The CDC says wear face mask, why didn't they understand that the mask protects everyone else from you and not you from the virus a month ago?

They did understand that. They just wanted to keep the masks available for the health care people who need them the most.

who are "they"? certainly the CDC knows that the mask's primary function is to protect others from you. But it also provides some protection for you.
what is a month ago?
