Yes, masks reduce the risk of spreading COVID, despite a review saying they don’t

An updated Cochrane Review published last week is the latest to suggest face masks don’t work in the community.

However there are problems with the review’s methodology and its underpinning assumptions about transmission. Well-designed real-world studies during the pandemic showed any mask reduces the risk of COVID transmission by 50–80%, with the highest protection offered by N95 respirators.
