Abstract:
:The current study aimed to determine the seroprevalence of Trypanosoma cruzi infection in Sucre State, Venezuela, and its association with epidemiological risk factors. The cluster sampling design allowed selecting 96 villages and 576 dwellings in the State's 15 municipalities. A total of 2,212 serum samples were analyzed by ELISA, HAI, and IFI. Seroprevalence in Sucre State was 3.12%. Risk factors associated with T. cruzi infection were: accumulated garbage, flooring and wall materials, type of dwelling, living in a house with wattle and daub walls and/or straw roofing, living in a house with risky walls and roofing, risky buildings and wattle and daub outbuildings, poultry inside the human dwelling, and presence of firewood. Infection was associated with individual age, and three seropositive cases were found in individuals less than 15 years of age. Sucre State has epidemiological factors that favor the risk of acquiring T. cruzi infection. :Resumen: El objetivo del presente estudio fue determinar la seroprevalencia de la infección por Trypanosoma cruzi en el estado Sucre (Venezuela) y su asociación con factores de riesgo epidemiológicos. El diseño muestral por conglomerados permitió seleccionar 96 centros poblados y 576 viviendas en los 15 municipios del estado. Asimismo, se evaluaron un total de 2.212 muestras de sueros, a través de las pruebas de ELISA, HAI e IFI. La seroprevalencia en el estado Sucre fue de 3,12%. Los factores de riesgo asociados a la infección por T. cruzi fueron: deposición de basura, materiales predominantes en el piso y paredes, tipo de vivienda, vivir en casas con paredes de bahareque y/o techos de palmas, vivir en casa con paredes y techos de riesgo, construcciones de riesgo y anexos de bahareque, aves dentro de la vivienda y la presencia de leña.

O delineamento da amostragem em clusters permitiu a seleção de 96 vilarejos e 576 moradias nos 15 municípios do Estado. No total, 2.212 amostras de soro foram analisadas com ELISA, HAI e IFI. O estudo mostrou uma soroprevalência de 3,12% no Estado de Sucre. Os seguintes fatores de risco estiveram associados à infecção pelo T. cruzi: acúmulo de lixo, materiais de piso e paredes impróprios, tipo de moradia, moradias com paredes de pau-a-pique e/ou teto de palha, moradias em situação de risco e construções anexas feitas de pau-a-pique, aves dentro das moradias e presença de lenha. A infecção esteve associada à idade individual, e três casos soropositivos foram identificados em indivíduos com menos de 15 anos de idade. O Estado de Sucre apresenta fatores epidemiológicos que aumentam o risco de infecção pelo T. cruzi.
