Masks are useless. Worn improperly they cause viral infections and other health problems.

Numerous RCTs (Random Clincial Tests) from several different years show that masks, including N-95 respirators, have no significant effect on viral transmission.

There are numerous studies showing they do work. Also most studies do not include masking the positives only the negatives. When you mask both positive and negative there will be a better effect.
