Abstract

Highlights: In one day, 4% (six of 150) of hospital visitors had asymptomatic COVID-19. Potential of visitors' viral shedding in healthcare facilities is underestimated. SARS-CoV-2 introduction into facilities is not fully blocked by universal masking. Abstract: In a single day, six of 150 (4%) asymptomatic visitors were diagnosed with COVID-19 at a hospital with a universal masking policy. Two inpatients (contacts) subsequently developed symptoms. More rigorous protective measures during visitation periods may need to be included in infection control practices to reduce nosocomial transmissions.
