Vahidy FS, Bernard DW, Boom ML, et al. Prevalence of SARS-CoV-2 Infection Among Asymptomatic Health Care Workers in the Greater Houston, Texas, Area. JAMA Netw Open. 2020;3(7):e2016451. doi:10.1001/jamanetworkopen.2020.16451
Asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection continues to be a major public health concern.1 Health care workers (HCWs) are at higher risk of infection and can become inadvertent vehicles of transmission.2 Therefore, Houston Methodist initiated a coronavirus disease 2019 (COVID-19) surveillance program among asymptomatic HCWs and expanded to asymptomatic community residents. We report prevalence of SARS-CoV-2 among the first group tested.
This cross-sectional study was approved by the Houston Methodist institutional review board as part of a quality improvement project that includes a waiver of informed consent from HCWs, per institutional policy. Community residents were recruited via telephone, and written informed consent was obtained in person. This study is reported following the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline.
