Distribution of the vector of the chagas disease triatoma dimidiata in settlements in the canton Bolivar, Ecuador

In order to know the distribution of the vector of the Chagas disease Triatoma dimidiata in the settlements of Arrastradero and El Limon, relevant information was collected on: characteristics of the population, types of housing, presence of hosts, knowledge of the disease, existence of patients with symptoms of the &Ruse. The entomological exploration was carried out to identify the potential hosts of T. cruzi. The settlements were characterized by consisting in average of more than two members, with predominant cement houses, pre-existing bamboo cane structures. The knowledge about the disease was higher in the Arrastradero sector (3.56%), fewer vectors (8.59%) and houses with triatomines (4.28%). While the population of El Limon the results were 2.44; 11.23 and 4.41% respectively. The vector found corresponded to Triatominos dimidiata in peridomestic and domestic sites, without natural infection with T. cruzi. It is concluded that the presence Triatoma dimidiata, does not rule out reinfestation with T. cruzi, so it is necessary to maintain a health plan to minimize the risks of a contamination with Chagas disease.
