There is not, and never has been, a single, solitary study, ever done that showed that community masking has any statistically relevant effect on the spread of outcome of any respiratory viral infection... PERIOD.
Never has been.
Masks are about control, and pandering to the cowardly, they provide absolutely no protection.
I was recently in hospital for 3 nites (freak thing)...half of doctors and @20% of nursing staff wore masks...I truly question their intelligence.
