CONCLUSIONS: Symptom and temperature reports are useful screening tools for predicting SARS-CoV-2 assay results in HCWs. Anosmia/ageusia, fever, and myalgia were the strongest independent predictors of positive assays. Therefore, we investigated the presenting symptoms most predictive of positive/negative SARS-CoV-2 RT-PCR results among HCWs. Since March 9, 2020, the occupational health service of a Massachusetts community healthcare system has implemented a staff "hotline" system to maintain a viable/healthy workforce and operational continuity during the pandemic. The clinical COVID-19 attack rate during the study period was calculated as: (the number of initial positive SARS-CoV-2 assays + the number of false negatives) divided by the system's estimated total HCW population (n = 4600).	./cache/cord-291360-z19ri377.txt	./txt/cord-291360-z19ri377.txt
