SARS-CoV-2 Infection Among Community Health Workers in India Before and After Use of Face Shields

Educational Objective
To understand the differences in the rate of COVID-19 infection before and after the use of face shields
1 Credit CME

The transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to be predominantly through respiratory droplets from infected persons in close proximity to uninfected persons,1 although airborne transmission may also play a role.2,3 Face shields have been proposed to prevent transmission in the community,4 but data are lacking. We describe transmission in a community setting before and after the use of face shields.
