Introduction. The COVID-19 pandemic has exposed many of the inequalities in society and one of the most neglected vulnerable populations are those deprived of their liberty. Objective. Determine the seroprevalence of SARS-CoV-2 in the population deprived of liberty (PDL) in two penitentiary institutions in Paraguay between April-May 2022. Materials and methods. Cross-sectional descriptive study in two penitentiary institutions in Paraguay, one for men and the other one for women, using two-stage probabilistic sampling. The blood samples were taken by fingerprint for the determination of anti-SARS-CoV-2 antibodies by a rapid IgG/IgM test (Orient Gene Biotech COVID-19 cassette). Descriptive statistics (mean, standard deviation (SD), percentages) and analytical statistics (chi square test) were used for data analysis. Results. A total of 602 PDL were included, 67% men and 33% women, the average age was 34 years (SD 10.71), 21% (n=124) with comorbidity, 31% (n=186) with complete vaccination. Of the 66 PPL (11%) who reported prior Covid-19 infection, 79% (n=52) developed symptoms and 6% (n=4) required hospitalization. In men, 95% presented positive serology (IgG and/or IgM) for SARS-CoV-2 (95% CI: 92.18-96.58) and 94% (95% CI: 89.65-96.83) in women. In the vaccinated group, seropositivity was 98.5% (95% CI: 97.11-99.25), and among the unvaccinated, 57% (95% CI: 53.22-70.29). Conclusion. The seroprevalence of SARS-CoV-2 was similar to that reported in other studies. The structural unhealthiness and overcrowding are factors that enhance the spread of the virus and emphasize the importance of encouraging vaccination in these populations.
