Of these, 29% were asymptomatic in the preceding months, and 69% had not previously received a diagnosis of SARS-CoV-2 infection.
  • Prevalence of SARS-CoV-2 antibodies was lower among personnel who reported always wearing a face covering while caring for patients (6%), compared with those who did not (9%). Seropositivity was lower among women (5%) than among men (7%).
