As of 7-27-21, the Centers for Disease Control and Prevention (CDC) updated its mask guidance for those who are vaccinated against COVID-19 in the wake of a significant surge of the Delta variant among unvaccinated Americans. The recommendations advise fully vaccinated individuals to wear masks indoors in places with high or substantial COVID-19 transmission rates. In addition, the agency is recommending universal mask wearing for all teachers, staff and students of K-12 schools even if fully vaccinated, citing a need to return to school this summer/fall. The decision comes ahead of a potential spike in cases this fall due to the Delta variant.
To help determine risk level and monitor COVID-19 cases across the country, the CDC released a dashboard tracking coronavirus data by county.
