CDC study finds masks don’t stop Covid19 infection

A CDC study found that wearing a mask made no difference to catching Covid19.

71% of case-patients (ie. infected) and 74% of control-participants (not infected) reported always using cloth face coverings or other mask types when in public.

The CDC didn’t highlight this finding, but the finding that people who caught Covid19 were twice as likely to have gone out to eat or drink.
