Residents of long-term care facilities have high COVID-19–associated morbidity and mortality. More information is needed about SARS-CoV-2 introduction and transmission in nursing homes.
What is added by this report?
Investigation of a COVID-19 outbreak in a Maryland nursing home identified a significantly higher prevalence among residents receiving dialysis (47%) than among those not receiving dialysis (16%); 72% were asymptomatic at the time of testing.
What are the implications for public health practice?
Nursing home residents undergoing dialysis might be at a higher risk for SARS-CoV-2 infection because of exposures to staff members and community dialysis patients. Attention to infection control practices and surveillance in nursing homes and dialysis
centers is critical to preventing nursing home COVID-19 outbreaks.
