Coronavirus Disease 2019 (COVID-2019) Infection Among Health Care Workers and Implications for Prevention Measures in a Tertiary Hospital in Wuhan, China

Key Points Question What are the exposure details and clinical characteristics of health care workers with coronavirus disease (COVID-19) in Wuhan, China? Findings In this single-center case series including 9684 health care workers, 110 of whom had COVID-19, a higher rate of infection was found among those working in the low-contagion area during the early stage of the disease outbreak, especially among nurses younger than 45 years. Most health care workers with COVID-19 had nonsevere disease, with an asymptomatic carrier prevalence of 0.9% and a mortality rate of 0.9%. Meaning In this study, most infections among health care workers occurred during the early stage of the COVID-19 outbreak and in low-contagion areas; routine screening may be helpful in identifying asymptomatic carriers.
