Abstract Objective We aimed to estimate prevalence of post-COVID conditions (PCC) among healthcare workers (HCWs) and to identify pre-disposing factors. Methods A cohort of Canadian HCWs completed four questionnaires during the pandemic. At the final questionnaire, HCWs reported conditions attributed to earlier COVID-19. The proportion developing a PCC was estimated. Risk factors were evaluated by logistic regression. Results Among 4964 HCWs, 995 had one positive COVID test >90 days before completing the final questionnaire. 266 (27%) developed a PCC. Factors predisposing HCWs to a PCC included depression and increased alcohol consumption reported pre-infection, chronic ill-health pre-pandemic, and a perception that the infection was work-related. PCCs were less likely following vaccination. Most HCWs (98%) returned to work within 30 days, with 8% reporting severe PCC (n = 80). Conclusions Pre-disposing factors reflected poor health pre-infection. Most conditions were mild.
