Indicadores entomológicos de Trypanossoma cruzi no Sertão Paraibano.

Abstract

Entomological indicators of Trypanossoma cruzi in the backlands of Paraiba. The objective of this study was to evaluate the potential of regions Sousa and Patos for maintenance of Chagas disease in the state of Paraiba in the periods 2005 to 2015. A descriptive retrospective study was carried out through consultations with epidemiological data of the Chagas disease control program of regional endemics laboratories of the Sixth and Tenth Regional Center of Paraiba Health, where the following data collection and identification of the insects were selected, detection and identification of T. cruzi. Entomological indicators of triatomine dispersion index were analyzed (DT), domiciliary infestation (ID), natural infection (IN) by T. cruzi. 20,418 insects were captured. Entomological indexes for the micro de Sousa and Patos had an average total of 39.5% dispersion index and 9.6% infestation rate of 4.2% and 0.5% and the positivity rate of 0.3% and 0.4% respectively. The species with the greatest number of insects with the potential vector for T. cruzi were Triatoma brasiliensis, Triatoma pseudomaculata, Panstrongilus lutzi. Given the results of this study we can conclude that it was verified the presence of triatomine in the regions of Patos and Sousa. The microregion of Patos noteworthy since had the highest entomological indices. Given the above it is suggested that the control measures are intensified by the responsible bodies in the regions to prevent the transmission of Chagas disease, control and eradication of triatomine vectors.
