LOAIZA, Lisbeth et al. Seroprevalence of chagasic onfection: "La Gavillera" neighbourhood, Negro Primero Parish. Carabobo State, Venezuela, 2007. Comunidad y Salud [online]. 2009, vol.7, n.1, pp.9-17. ISSN 1690-3293.

Chagasic infection has become an accurate sample of health problems in Latin America. Because of its endemicity in rural areas of Carabobo State, a seroprevalence survey was performed. Its aim was to determine prevalence of Chagasic infection, characterize human dwellings, triatomid infestation and their taxonomy and a parasitological determination of infection in collected vectors. A descriptive, cross tabulated and prospective pattern was applied. Average, standard deviation and percentage analysis were performed. 20.9% of the sample were positive and among them, 58.6% were females with an age average of 48.7+- 13.9 years and 46+- 12.68 years in males. Most of human dwellings were wattle and daub structures, with palm roofs and dirt ground. 20% of them infestated with vector triatomids, among them: 81.9%, were Panstrongylus geniculatus and Trypanosoma rangeli, was the most prevalent parasite. Conclusion aims that that deficiencies in human dwellings is the cause of maintenance of Chagasic seroprevalence assessed in the present survey.
