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

摘要

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.
