Fig. 4: Associations between occupations and seroprevalence of SARS-CoV 2 IgG antibodies among HCW with patient contact.
From: SARS-CoV-2 exposure, symptoms and seroprevalence in healthcare workers in Sweden
Odds ratios of seropositivity for groups of HCW with patient contact, compared to personnel without patient contact. Odds ratios were calculated using two-sided Fisher’s exact test with n = 733 (assistant nurses vs no patient contact), n = 941 (nurses vs no patient contact), n = 744 (physicians vs no patient contact), and n = 559 (other medical staff vs no patient contact) independent plasma samples. No adjustment for multiple comparisons was applied. Data are presented as odds ratios and 95% confidence intervals. Source data are available as Source Data file.
