Between April and September 2020, a study on 396 healthcare workers at Chris Hani Baragwanath Hospital in South Africa found a 34.6% infection rate of SARS-CoV-2, with the internal medicine department having the highest rate of infection. Most confirmed cases exhibited symptoms.
From April to September 2020, we investigated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in a cohort of 396 healthcare workers (HCWs) from 5 departments at Chris Hani Baragwanath Hospital, South Africa. Overall, 34.6% of HCWs had polymerase chain reaction-confirmed SARS-CoV-2 infection (132.1 [95% confidence interval, 111.8-156.2] infections per 1000 person-months); an additional 27 infections were identified by serology. HCWs in the internal medicine department had the highest rate of infection (61.7%). Among polymerase chain reaction-confirmed cases, 10.4% remained asymptomatic, 30.4% were presymptomatic, and 59.3% were symptomatic.
