Seroprevalence of SARS-CoV-2 in a Large Cohort of Italian Police Officers

Certain professional categories are at a high occupational exposure to COVID-19. The aim of this survey was to quantify the seroprevalence of SARS-CoV-2 among police officers in Italy and identify its correlates. In this cross-sectional study, a nationally representative sample of State police emplo...

The aim of this survey was to quantify the seroprevalence of SARS-CoV-2 among police officers in Italy and identify its correlates. In this cross-sectional study, a nationally representative sample of State police employees was tested for IgG and IgM before the start of the National vaccination campaign. A total of 10,535 subjects (approximately 10% of the total workforce) participated in the study. The overall seroprevalence was 4.8% (95% CI: 4.4–5.3%). However, seropositivity was unevenly distributed across the country with a clear (<i>p</i> < 0.001) North–South gradient.

Most (71.2%) seropositive subjects reported having no recent symptoms potentially attributable to SARS-CoV-2 infection.

A significant risk of occupational exposure, frequent asymptomatic cases and the progressive waning of neutralizing antibodies suggest that the police workers should be considered among the job categories prioritized for the booster COVID-19 vaccine dose.Sergio GarbarinoAlexander DomnichElisabetta CostaIrene GibertiStefano MoscaCristiano BelfioreFabrizio CipraniGiancarlo IcardiMDPI AGarticleCOVID-19SARS-CoV-2seroprevalencepolice officersoccupational exposureItalyMedicineRENInternational Journal of Environmental Research and Public Health, Vol 18, Iss 12201, p 12201 (2021)
