Staff working in dedicated COVID-19 wards showed substantially higher rates of seropositivity (1·65 [1·34-2·03]; p<0·001) than other frontline health-care workers working in hospitals, reflecting increased risk for this group, a pattern that has also been reported in neighbouring Sweden. The results highlight the risk that SARS-CoV-2 can pose to health-care workers, particularly those in regular contact with patients with COVID-19, and the importance of understanding possible routes of exposure in hospitals. However, the prevalence of asymptomatic SARS-CoV-2 infections and COVID-19-like symptoms among seronegative staff illustrates the limitations of relying on symptom-based surveillance alone.
