Abstract

We describe the impact of universal masking and universal testing at admission on high-risk exposures to severe acute respiratory syndrome coronavirus 2 for healthcare workers. Universal masking decreased the rate of high-risk exposures per patient-day by 68%, and universal testing further decreased those exposures by 77%.

Keywords: PPE; SARS-CoV-2 transmission; aerosol generating procedure; hospital epidemiology; universal masking.
