Multiple studies show that face masks reduce the spread of COVID-19; a Cochrane review doesn’t demonstrate otherwise – Health Feedback

Claims that face masks don’t work based on the results of the Cochrane review are unsupported and misrepresent the conclusions of the review, which couldn’t draw “any firm conclusions” on the effectiveness of mask-wearing at limiting the spread of respiratory infections due to methodological limitations. Many of those claims also mislead the readers by presenting the review as high-quality definite evidence without adequately acknowledging its limitations. While meta-analyses are indeed at the top of the quality evidence pyramid, their reliability depends on the quality of the individual studies they include, which is highly variable in the case of face masks.

A growing body of evidence from RCTs and observational studies suggests that consistent mask-wearing can effectively reduce the spread of respiratory viruses like SARS-CoV-2 in both healthcare and community settings. The extent to which community mask-wearing contributes to limiting the spread of different respiratory viruses and in different circumstances is still unclear. Hopefully, future well-designed studies will answer these questions. For the time being, face masks are another layer of protection in addition to vaccination, frequent handwashing, and physical distancing when the circulation of respiratory viruses is high.
