Entomological survey and characterization of houses with the vector of Chagas disease, in Chuchuapa village, Santa Rosa, Guatemala ; Encuesta entomológica y caracterización de las viviendas con el vector de la enfermedad de Chagas, en aldea Chuchuapa, Santa Rosa, Guatemala

in Guatemala in 2015, the Ministry of Public Health and Social Assistance reported new cases of Chagas disease in the southeastern region of the country, with Santa Rosa being one of the endemic departments where Triatoma dimidiata is the main transmitter. The infestation of T. dimidiata was estimated in the Chuchuapa village, municipality of Santa María Ixhuatán, from April to June 2019, the entomological indices were calculated and 149 dwellings were characterized intradomiciliary and peridomiciliary (79.67% of the inhabited dwellings). The data were obtained through a mixed questionnaire, in a face-to-face interview and evaluation of the dwellings, by an experienced professional team, using the standard man-hour method and protocol. 20 triatomines were captured in 10 homes, with an infestation index of 6.71% (10/149), a density index of 13.42% (20/149), 19 intradomiciliary triatomines and one peridomiciliary, with a natural infection index by intradomiciliary Trypanosoma cruzi of 26.3% (5/19), natural infection index by peridomiciliary T. cruzi of 100.0% (1/1) and natural infection index by T. cruzi in captured triatomines of 30.0% (6/20). The infested dwellings have a sheet roof, wattle, and daub wall with cracks and no wall plaster, dirt and posters on the wall, accumulation of firewood and other materials in both intradomiciliary and peridomiciliary, living with domestic animals, and keeping poultry animals. The results represent a high risk for the transmission of Chagas disease among the villager. ; En Guatemala en el 2015, el Ministerio de Salud Pública y Asistencia Social (MSPAS) reportó nuevos casos de la enfermedad de Chagas en la región suroriental del país, siendo Santa Rosa uno de los departamentos endémicos en donde Triatoma dimidiata es el principal transmisor.
