Healthcare workers (HCWs) are at risk for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection due to increased occupational exposure to SARS-CoV-2 (Nguyen et al., 2020). As well as being beneficial for the HCWs themselves, protecting HCWs from SARS-CoV-2 infection is important to prevent disease transmission in healthcare and community settings (Anonymous, 2020). In addition, protecting HCWs from coronavirus disease 2019 (COVID-19) is crucial for the preservation and protection of national healthcare systems (Anonymous, 2020).
