Popis: Background. Guanajuato state in Mexico has high frequency of confirmed cases of COVID-19. Health-care workers are the most exposed to contagion due to contact with patients infected by SARS-CoV-2. The objective was to know the seroprevalence of antibodies (IgG) anti-SARS-CoV-2 in health-care workers from Secretary of Health from Guanajuato State. Material and methods. It was a cross-sectional, retrolective study, using database from the ENSERO-COVID program. It was recollected data about exposure in work and in community by contact with confirmed cases of COVID-19. The anti-SARS-CoV IgG antibody titer was determined, considering 1.4 or higher as positive. It used Chi squared test to show relationship between variables, Z for two proportions to test hypotheses and logistic regression for show the effect of exposure and test positive for antibodies. Results. 4,047 registries were reviewed, 376 (9.29%) were positive for the presence of SARS-CoV-2 antibodies. There is an association between the type of work unit (type determined by hospitalizing COVID-19 patients or not) with seropositivity (P
