'After the first wave of Omicron, there was no significant difference in people always wearing a mask from those never wearing them,' experts told Newsweek.
Wearing face masks may not have lowered the risk of COVID infection after the first Omicron wave, new research has shown. But that does not mean that face masks aren't useful, regardless.The wearing of face masks on public transport and airplanes was federally mandated in the United States in February 2021 in a big to stop the spread of COVID-19. However, in April 2022, the mandate was ruled unlawful.
'Early in the pandemic there were many studies published looking at risk factors for catching COVID, but far fewer studies after the first year or so,' Hunter said. 'Our research shows that there were changes in some risk factors around the time that the Omicron BA.2 variant became dominant.'In November 2021, always wearing a face mask at work, school or in enclosed spaces was associated with a reduced risk of COVID infection in both adults and children.
