“…The prevalence found in the indigenous communities studied was higher than that estimated in the total population of Santa Fe province (4%) [14], [15]. These data coincide with the increased seroprevalence found in other works in indigenous communities of Gran Chaco compared to the general population [6], [16].…”

Background & objectivesIn Latin America, Chagas disease is endemic, with high prevalence in rural indigenous communities and increasing prevalence in urban areas due to migration from rural areas with active vector transmission. The objective of the work was to assess differences in the prevalence of Chagas disease in urban and rural moqoit communities of the south of Gran Chaco, Santa Fe province, Argentina.MethodsA seroprevalence study was conducted in six moqoit populations. Belonging to an urban community was considered as an exposure variable, whereas seropositivity for Chagas disease was considered as an outcome variableResultsThe results showed that 9.26% of the 702 volunteers evaluated and 3.50% of women of childbearing potential were seropositive. The prevalence of Chagas disease in urban communities was 6.41 times higher than in rural communities.Interpretation & conclusionsThe seroprevalence found in the moqoit community is higher than that estimated for the general population of the same region, with greater impact in the urban area than in the rural area. The decline of vector transmission in the rural area could be related to the conservation of ancestral practices and the expansion of the agricultural model.

Background: In Latin America, Chagas disease is endemic, with a high prevalence in rural indigenous communities and an increasing prevalence in urban areas owing to migration from rural areas with active vector transmission. This study aimed to assess differences in the prevalence of Chagas disease in urban and rural moqoit communities, one of the main ethnic indigenous groups in the south of Gran Chaco.Methods: A seroprevalence study was conducted in six moqoit populations in the Santa Fe province, Argentina. The variables studied were serology results for Chagas disease, residents of urban or rural areas, age, and sex. Results:The results showed that 9.26% of the 702 volunteers evaluated and 18.32% of the 131women of childbearing potential were seropositive. According to the calculated prevalence ratio, the prevalence of Chagas disease in urban communities was6.41 (95% confidence inverval: 3.73-11.02) times higher than that in rural communities: 21.59% in urban communities vs. 3.37%in rural communities. Conclusions:The seroprevalence found in the moqoit community was higher than the estimated level for the general population of the same region, with a greater impact in urban areas than in rural areas. The urbanization of groups of people with poor socio-sanitary conditions in the second half of the 20th century could have caused this higher seroprevalence of Chagas disease.

“…Entomological T. cruzi transmission persists in the Gran Chaco region, extends over sections of Argentina, Bolivia, and Paraguay, which is considered hyperendemic for CD. Rural populations and indigenous communities in this region have large prevalence rates of CD infection and very limited access to diagnosis and treatment [4][5][6].…”
