Studies of Surgical Masks Efficacy: Masks are useless in preventing the spread of disease (even during surgery)

Masks are useless in preventing the spread of disease and, if anything, are unsanitary objects that themselves spread bacteria and viruses.

JAMES FETZER — As a person who went to medical school, I was shocked when I read Neil Orr’s study, published in 1981 in the Annals of the Royal College of Surgeons of England. Dr. Orr was a surgeon in the Severalls Surgical Unit in Colchester. And for six months, from March through August 1980, the surgeons and staff in that unit decided to see what would happen if they did not wear masks during surgeries. They wore no masks for six months, and compared the rate of surgical wound infections from March through August 1980 with the rate of wound infections from March through August of the previous four years. And they discovered, to their amazement, that when nobody wore masks during surgeries, the rate of wound infections was less than half what it was when everyone wore masks. Their conclusion: “It would appear that minimum contamination can best be achieved by not wearing a mask at all” and that wearing a mask during surgery “is a standard procedure that could be abandoned.”

I was so amazed that I scoured the medical literature, sure that this was a fluke and that newer studies must show the utility of masks in preventing the spread of disease. But to my surprise the medical literature for the past forty-five years has been consistent: masks are useless in preventing the spread of disease and, if anything, are unsanitary objects that themselves spread bacteria and viruses.

  • Ritter et al., in 1975, found that “the wearing of a surgical face mask had no effect upon the overall operating room environmental contamination.” […]

  1. ICU doctor runs 22 miles while wearing mask to prove it doesn’t drop oxygen levels

    “My mask protects you, your masks protects me and everybody else,” Lawton stressed. “Unfortunately, the other message is there isn’t a magic bullet.” … He encourages everyone to continue to social distance, isolate if necessary and wear masks indoors.

    Again the obvious question which is never asked and so never answered: If I also have to wear a mask, what good is yours?
