Some mask wearers were found to have up to 40 percent higher incidence of infection, contradicting earlier studies and opposing the narrative of mask mandates.

People who wore protective masks were found to be more likely to contract COVID-19 infections than those who didn’t, according to a recent Norwegian study.

The peer-reviewed study, published in the journal Epidemiology and Infection on Nov. 13, analyzed mask use among 3,209 individuals from Norway. Researchers followed them for 17 days, and then asked the participants about their use of masks. The team found that there was a higher incidence of testing positive for COVID-19 among people who used masks more frequently.

Among individuals who “never or almost never” wore masks, 8.6 percent tested positive. That rose to 15 percent among participants who “sometimes” used masks, and to 15.1 percent among those who “almost always or always” wore them.
