Abstract

Objective: Considering the seriousness of the covid-19 pandemic and the exposure of workers in essential services, this study aimed to assess the SARS-Cov-2 infection rate and the seroprevalence of IgM and IgG antibodies in military police officers in a city in northeastern Brazil. Methods: This cross-sectional observational study comprised 139 police officers. They completed a brief socio-epidemiological questionnaire, and biological material was collected to carry out RT-PCR and immunofluorescence tests (IgM and IgG). Results: We found that 44.6% had positive RT-PCR, with a seroprevalence of 2.2% and 10.1% for IgM and IgG, respectively. But almost half of those positive were asymptomatic. There was a significant association between the presence of the two antibodies, with OR= 20.7 (p = 0.02). Conclusion: These results reinforce the need for testing and immunization in this category, in order to guarantee the safety of the professionals and those that they assist.
