On July 27, 2021, the Centers for Disease Control and Prevention (CDC) updated its COVID-19 guidance. The revised guidance, which has significant implications in the employment context, recommends that fully-vaccinated individuals wear masks in “public indoor settings in areas of substantial or high transmission.” The guidance further recommends that vaccinated persons be tested after a known or suspected COVID-19 exposure. The CDC’s guidance reverses its May 2021 guidance, which advised that fully-vaccinated individuals could generally stop wearing masks and cease social distancing. The CDC’s new guidance comes amidst a recent uptick in COVID-19 cases stemming from the highly-infectious Delta variant and is already complicating employers’ COVID-19 policies and return to work plans.
Updated masking recommendation
The CDC’s revised guidance acknowledges that fully vaccinated individuals can become infected with COVID-19 despite being vaccinated in a “breakthrough” infection. The CDC further acknowledges that, while breakthrough infections “happen in only a small proportion of the people who are fully vaccinated,” individuals with breakthrough infections can spread COVID-19. As a result of these concerns, while not referencing the workplace specifically, the CDC now recommends that all individuals, regardless of vaccination status, wear masks in public indoor settings in areas of substantial or high transmission.
