Dengue, Chikungunya, and Zika viruses are arthropod-borne viruses (arboviruses) that infect millions of individuals in tropical and subtropical regions. In the Americas, arboviruses represent a major public health problem, especially among vulnerable groups such as the elderly, children, and pregnant women. In this study, the seroprevalence of IgM or IgG against these arboviruses in pregnant, young women in the city of Diamantina, Minas Gerais, Brazil, and the influence of sociodemographic factors on the incidence/prevalence of infection in this group were investigated. A cross-sectional investigation was conducted on a total of 135 pregnant women for Dengue and Chikungunya IgM and 88 pregnant women for Zika IgG. Dengue IgM was found on the serum of twenty participants (14.8%) and only one woman (0.7%) tested positive for Chikungunya IgM. Zika IgG was found in three (3.4%) participants and 2 women who tested positive for Zika virus were also positive for Dengue virus IgM. Although the arboviruses seroprevalence was higher frequency among young (20–25 years old), brown and high school women, with a monthly income of 1–3 minimum wages, no association between these sociodemographic factors and arboviruses seroprevalence was found.
