Topic:

  • Facility-wide testing for SARS-CoV-2 in nursing homes following the identification of an initial COVID-19 case in the facility yielded a prevalence of 12%, compared to 0.4% when facility-wide testing was conducted in nursing homes without a previous COVID-19 case. In facilities with a previous COVID-19 case, it was estimated that for each additional day before completion of facility-wide testing, an estimated 1.3 additional cases were identified.
