Study: Covid face masks didn’t stop spread of Omicron – UnHerd

Face masks have not been effective at preventing the spread of Covid-19 since at least February 2022, according to a new study from the University of East Anglia.

Mask mandates were in place well into spring that year, but masks did not lower the risk of Covid infection after the initial Omicron peak that February, researchers found. Before Omicron, masks could reportedly reduce transmission by about 19%, but afterwards there was no relationship between consistent masking and risk of infection.

The research also demonstrates a weak relationship between childhood masking and infections. While school-aged children who never masked were more likely to be infected up until February 2022, after that point those who didnt wear masks actually had a much lower likelihood of infection, though the difference was often statistically insignificant.
