Sanchez, G., Biedron, C., Fink, L., et al. (2020). Initial and Repeated Point Prevalence Surveys to Inform SARS-CoV-2 Infection Prevention in 26 Skilled Nursing Facilities - Detroit, Michigan, March-May 2020. Morbidity and Mortality Weekly Report. 69(27):882-886.
The authors describe facility-wide point prevalence testing for SARS-CoV-2 at 26 skilled nursing facilities in Detroit. Overall, 55% of those with symptom data available were symptomatic at the time of their first positive test. The authors suggest that symptom-based screening is inadequate to detect infection in skilled nursing facilities and repeated point prevalence surveys can improve identification of asymptomatic cases, implementation of infection prevention practices, and prioritization of resources.
