Abstract

We measured severe acute respiratory syndrome coronavirus 2 spike protein subunits S1/S2 antibodies by using capillary electrophoresis and a chemiluminescence immunoassay for 5,444 active healthcare workers in Italy. Seroprevalence was 6.9% and higher among participants having contact with patients. Seroconversion was not observed in 37/213 previously infected participants.

Seroprevalence of severe acute respiratory syndrome coronavirus 2 antibodies in healthcare workers according to tasks of participants, Turin, Italy. Participants are grouped according to direct (black bars) or indirect/no contact (gray bars) with patients. The difference between these 2 groups (7.5% vs. 5.2%) is significant (p = 0.013 by χ2 test). The healthcare personnel category includes psychologists, nutritionists, welfare workers, religious assistants, physical therapists, and orthoptists.
