It has to do with the hospitals filling up with Covid patients, as they are in Texas, Arizona, and Florida now (easily findable headlines, I won’t bother citing). If hospitals fill up and people can’t be treated (for Covid or other ailments) more people die. The other part is masks reduce transmission of Covid by “up to 85%” according to the WHO. So you put those two together and it’s a good public health policy.
