Identifying airborne transmission as the dominant route for the spread of COVID-19

June 10, 2020

Face masks and COVID-19 transmission

A comparison of trends in COVID-19 infections and mortality in Italy and New York City, before and after the implementation of mandatory face mask use, suggests that this measure prevented more than 70,000 infections in Italy between April 6 and May 9, and more than 66,000 infections in New York City between April 17 and May 9, suggesting that airborne transmission may play a major role in COVID-19 spread.

Dr. Mario Molina along other scientists wrote a paper on the use of facemasks and COVID-19 transmission. It will be published by PNAS (Proceedings of the National Academy of Sciences) next week, but you can read it now here:
