The role of supporting services in driving SARS-CoV-2 transmission within healthcare settings: a multicenter seroprevalence study.

Abstract Objective Determining the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in health care workers (HCWs) based on risk of exposure to COVID-19 patients. Methods SARS-CoV-2 seroprevalence cross-sectional study in risk-stratified HCWs randomly selected from 3 main district hospitals in Oman. Results 1,078 HCWs included with an overall SARS-CoV-2 seroprevalence of 21%. The seropositivity in low, variable, and high risk groups were 29%, 18%, and 17%, respectively (P-value Conclusion The low risk supporting services workers can drive SARS-CoV-2 transmission in hospitals. More attention and innovation within this opportunity will enhance the safety of health care during epidemics/pandemics.
