Masks Do Reduce Spread of Flu and Some Coronaviruses, Study Finds

April 3, 2020

(Reuters) – Face masks could help limit the spread of the COVID-19 pandemic, according to researchers who studied the effect of surgical masks on the transmission of other corona and flu viruses. In the study, the use of surgical masks by sufferers significantly reduced the number of flu viruses detectable in droplets released through breathing and coughing. It also reduced the number of seasonal coronaviruses – among the causes of common colds – detectable in the air as suspended microdroplets, or aerosols. The study did not look at the new coronavirus, SARS-CoV-2.
