Healthcare workers are at an increased risk of infection, harm and death from COVID-19. Close and prolonged exposure to individuals infectious with SARS-CoV-2 leads to infection. A person's individual characteristics (age, sex, ethnicity and comorbidities) then influence the subsequent risk of COVID-19 leading to hospitalisation, critical care admission or death. ⋯ However, the available evidence suggests that the risk for this group of individuals is not currently increased. This review examines factors associated with increased risk of infection with SARS-CoV-2, increasing severity of COVID-19 and death. A risk tool is proposed that includes personal, environmental and mitigating factors, and enables an individualised dynamic 'point-of-time' risk assessment.
