Hospital-Wide SARS-CoV-2 Antibody Screening in 3056 Staff in a Tertiary Centre in Belgium

Study (n=3,056) found being involved in clinical care & exposure to COVID-19–positive co-workers were not significantly associated with seroprevalence; but having a COVID-19-positive household contact was (odds ratio 3.15 (95% CI, 2.33-4.25), p< 0.001).

SPS commentary:

Study also reports a high proportion of staff mentioned at least 1 prior symptom (2294/3052 [75%]). Of those with antibodies, 30 of 197 (15%) reported no symptoms. Prior anosmia (loss of sense of smell) was significantly associated with the presence of antibodies, as well as fever and cough.
