aWe adjusted all analyses for daily COVID-19 incidence among hospitalized PUIs. For total duration of PUI status, we were unable to additionally adjust for changes in test result return time owing to the introduction of additional in-house assays.
bPatients who did not have PUI status discontinued owing to death or discharge, or who were converted to CoV-Presumed status (defined in Study Setting and Design) or confirmed to have COVID-19 by subsequent NAAT were excluded from the 2 analyses regarding the duration of PUI status.
