Identifying Contact Risks for SARS-CoV-2 Transmission to Healthcare Workers during Outbreak on COVID-19 Ward

Marius Zeeb et al. Emerg Infect Dis. 2022 Oct.

Abstract

We assessed the risk for different exposures to SARS-CoV-2 during a COVID-19 outbreak among healthcare workers on a hospital ward in late 2020. We found working with isolated COVID-19 patients did not increase the risk of COVID-19 among workers, but working shifts with presymptomatic healthcare coworkers did.

Keywords: COVID-19; SARS-CoV-2; contact tracing; coronavirus disease; disease outbreaks; healthcare delivery; healthcare personnel; infectious disease transmission; patient-to-professional; risk factors; severe acute respiratory syndrome; severe acute respiratory syndrome epidemiology; severe acute respiratory syndrome transmission.

Hazard ratios and the 95% CIs for HCWs to acquire SARS-CoV-2 after using SPM and IPM for patient contact and HCW contact (i.e., contact with positive HCWs) during COVID-19 outbreak in hospital ward, Switzerland, October–November 2020. The multivariable model combined patient contact using SPM and IPM and HCW contact. HCW, healthcare worker; HR, hazard ratio; IPM, isolation precaution measures; SPM, standard precaution measures.
