Surveillance of Chagas disease vectors in municipalities of the state of Ceará, Brazil.
The present study aimed to analyse the dwelling infestation rates and the distribution and natural Trypanosoma cruzi infection rates, among triatomines captured in the 13 municipalities of the state of Ceará. The records relating to the capture of intradomicile and peridomicile triatomines during the Chagas disease control program of 1998-2008 were available. Among the triatomines captured and in all of the municipalities studied, Triatoma brasiliensis presented the highest incidence in intradomicile and Triatoma pseudomaculata in peridomicile and some were positive for infection by T. cruzi. We emphasise that it is important to have sustainable epidemiological surveillance in the region, since when the control measures decreased, the incidence of T. pseudomaculata in intradomicile grew.
