Introduction: The chikungunya virus has already been identified in more than 60 countries in Asia, Africa, Europe and the Americas, and chronicity after the disease impacts the lives of those affected by the virus, as well as society, the economy and public health. The objective was to characterize, through epidemiological survey, the profile of chikungunya infection in a mid-sized municipality in Mato Grosso according to sociodemographic and sanitary factors. Methods: The serum-epidemiological survey was conducted with 596 adults aged ≥ 18 years selected by cluster sampling process, with application of questionnaires and biological material collection. Positive cases of chikungunya fever were those with positive results in the anti-chikungunya virus enzyme immunoassay (ELISA). The statistical analyses used descriptive and inferential techniques with confidence intervals of 95% and a significance level of 5%. Results: The overall prevalence of chikungunya fever found in the community was 8.4%. The profile of infection by chikungunya fever is composed of women (p<0.204), aged between 18 and 39 years (p<0.780), more than 08 years of study (p<0.079), non-white reported race/color p<0.871) and employed in the past 12 months (p<0.927). Not residing with affective companion was statistically significant for infection by chikungunya virus (CHIKV) (p<0.028). Conclusion: The study found that women are the most affected by the infection, as well as being single represented a risk factor, and risk behaviors, such as presence of larvae and breeding of mosquitos at home, reflect a low level of awareness of the disease.
