A área profissional está associada à soroconversão para SARS-CoV-2 entre os profissionais do SESC-DF? Um estudo transversal

Abstract

The aim of the study was to analyze the prevalence of seroconversion to antibodies against SARS-CoV-2 in health professionals working at SESC-DF and compare it with the prevalence of professionals who do not belong to the health field, such as commercial and administrative staff; and also test the associations. The cross-sectional study was conducted between June and August 2020 among all 838 SESC-DF professionals who were working during the COVID-19 pandemic.  The Acro Biotech® antibody Rapid Test IgG/IgM COVID-19 was used to test the professionals. The covariates were work hours a month, age, sex, presence of comorbidities, date of the COVID-19 test; the presence of a symptomatic relative, and the need to be absent from work due to suspected SARS-CoV-2 infection. Descriptive analysis, Pearson chi-squared test, and hierarchical logistic regression were performed. Of the total 93 health professionals, 14 (15.10%) presented seroconversion while from 745 professionals who do not belong to the health field 100 (13.40%) presented seroconversion with no statistical difference (p=0.78 chi-squared test). The date of testing between 07/15 to 07/31 (Odds Ratio (OR) 8.53; 95% CI 1.18-61.51, p=0.03) and the presence of a symptomatic relative (OR 2.28; 95% CI 1.17-4.44; p=0.01) were associated with seroconversion. Employees with SARS-CoV-2 seroconversion presented 37.80 odds of absence from work (95% CI 22.35-63-91; p <0.001). Seroconversion was not associated with the professional field but with the date of testing, symptomatic relative, and absence from
