^a HCWs not measuring their temperature were assumed to not have elevated body temperature as a sensitivity analysis

^b Adjusted for age, sex, and all symptoms, i.e. fever, cough, shortness of breath, myalgia, malaise, sore throat, nasal symptom (runny, sneezing, congestion, sinus), gastrointestinal symptom (nausea/ vomiting/ diarrhea), rash, anosmia/ageusia (i.e. loss of smell/loss of taste), and headache

^c Adjusted for all variables as above except fever
