To this day there are to my knowledge still no randomized control trials whatsoever finding any substantial evidence that face coverings reduce the transmission of viruses or number of confirmed cases of virus-induced illness.

no, we have the exact opposite, we have a study proving you cannot transmit the flu.

seriously.. science says we can't get past this.

they say we can't test it because it is unethical.

fine, then the result is zero proof.

it never has existed.

what does exist.. are bacteria. bacteria from a corpse if introduced into a body thru surgery (get them in past your defenses) .. this can/is a provable problem that sanitization did help.

it was from a corpse touching doctors who then went on to do surgery.. this guy, Ignaz Semmelweis apparently figured it out.

we have proof of that
