COVID-19 Masking Guidelines January 2022
The City of St. Louis Department of Health joins the Centers for Disease Control and Prevention in advising the wearing of face masks for all individuals who are able to do so appropriately.
Masks: Materials and Wearing
The CDC advises wearing face masks [www.cdc.gov] or respirators for all individuals who are able to appropriately do so. The City of St. Louis Department of Health recommends that everyone properly wear a face mask when in public spaces and when they will be in the company of anyone who does not live in their household. When worn properly, face masks primarily contain exhaled respiratory droplets and particles, while providing some protection against inhaling materials exhaled by others. Respirators protect against inhalation of particles as well as containing exhaled respiratory droplets and particles.
