Results of rRT-PCR for SARS-CoV-2 and symptom onset among index case-patients, SARS-CoV-2–positive household contacts, and SARS-CoV-2–negative household contacts in study of initial virus shedding in SARS-CoV-2, Utah, USA, April–May 2020. The timelines of symptom onset and testing dates preceding and during the 15-day study period are ordered by individual households (HH-01–HH-05). Sex and age (in parentheses) are listed to the left. Symptom onset date is only included for household members who tested positive at any time during the study period or for whom onset of symptoms consistent with coronavirus disease prompted an interim visit from investigators. HH-05 opted out of day 14 nasopharyngeal specimen collection. Ct, cycle threshold; HH, household; rRT-PCR, real-time reverse transcription PCR; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
