Seroprevalence of Chagas disease in urban and rural indigenous populations of the south of Gran Chaco.

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.

[Seroprevalence of Chagas´Disease in older than 14 years old in rural Chaco areas of Santa Fe Province.].

Introduction: Chagas´Disease (CD) is endemic en Chaco Región. It is unknown the seroprevalence in population older than 14 years old from rural Chaco areas of Santa Fe Province. This study aimed to determine the seroprevalence of and socio-environmental factors associated with CD in inhabitants >14 years old of rural Chaco areas of Santa Fe, Argentina.

Diagnostic reliability of an immunochromatographic test for Chagas disease screening at a primary health care centre in a rural endemic area.

Many patients with Chagas disease live in remote communities that lack both equipment and trained personnel to perform a diagnosis by conventional serology (CS). Thus, reliable tests suitable for use under difficult conditions are required. In this study, we evaluated the ability of personnel with and without laboratory skills to perform immunochromatographic (IC) tests to detect Chagas disease at a primary health care centre (PHCC).
