“…In this situation the prevalence of R. nasutus was observed, a fact that can be explained by presence of straws and birds. In the roofs of the goat and sheep corrals and hen-houses T. brasiliensis associated to T. pseudomaculata was frequently found, however, always with prevalence of the first, as already mentioned by Alencar (1987), Bento et al (1989), and Gomes (1993).…”

In order to assay the triatomine infestation and domiciliation in the ruralIn the state of Ceará, the presence of triatomines has been known for a long time, as Alencar (1987) has shown in a research that compiled former surveys carried throughout the state. Alencar et al. (1976) have demonstrated that vectors have not been found in only 9 out of the 141 municipal districts that comprise the geographic division of the whole state of Ceará. The authors have cited the semi-domestic Triatoma brasiliensis as being a primary transmitting species and with larger distribution in that state, found in 91.5% houses of municipal districts, many times with high Trypanosoma cruzi infection indexes. Triatoma pseudomaculata, which is believed less domestic, was found in 68.8% of the municipal districts, with an average infection index of 4.2%. In the distribution ranking, the third species in Ceará was Panstrongylus megistus, displaying a variable infection index; this species was found in 61.7% of the municipal districts. Rhodnius nasutus, with an average of 1% infection index, was found in 17.7% of the municipal districts; Panstrongylus lutzi was found in 18.4% of the municipal districts, presenting an average of 17.9% of infection indexes (Alencar et al. 1976).The objective of the present work was to determine infestation indexes, colonization, and density of triatomines in domiciliary units (DUs) that include intradomicile, peridomicile, and ecotopes found in wild habitats of the four localities that belong to the rural area of Jaguaruana municipality, Ceará, Brazil, formerly considered to be highly infested by these vectors. The indexes were determined by relating them with variables such as type of house's wall type and number of peridomiciliary annexes. The authors have also determined the indexes of natural T. cruzi infection in triatomines captured in each studied habitat and ecotopes.

“…In the same period, it was demonstrated that the municipality of Oeiras was considered an area of active transmission due to the presence of domiciliary triatomines infected with T. cruzi, and children under 5 years old presenting positive serology for the disease 21 . In addition to this study, several others were carried out showing both, the distribution and the seropositivity of triatomines in the State [22][23][24][25][26] .…”

“…Bento et al ., [11] in 1984–1985, identified 21.7% of seropositivity for Chagas disease among 566 people investigated in a rural population from municipalities of Castelo do Piauí and Pedro II, and a rate of 22.1% among 169 children under the age of 10 years examined in the population. In 1996, Coura et al ., [12] in a study carried out in the urban and rural areas of the municipalities of Oeiras and Colônia do Piauí, identified a 5.9% positivity rate for Chagas disease among 4212 residents analysed and 0.5% of infection by T. cruzi in the population of children under 10 years of age.…”

Objectives This manuscript aimed to evaluate the seroprevalence of Chagas’s disease in the population of rural communities at Campinas do Piauí city, State of Piauí, Brazil. Methods The techniques of the indirect immunofluorescence reaction and enzyme‐linked immunosorbent assay were used to detect reagent samples for Chagas disease and estimate its prevalence in the rural population. Blood samples were collected on filter paper through digital and venipuncture. Blood samples with reactive or indeterminate results were re‐evaluated and subjected to the test by ELISA. Results In total, 763 blood samples were analysed from 161 residences of 18 rural communities, collected in residents aged between 2 and 92 years. In the indirect immunofluorescence reaction technique, 44 (5.8%) of the results were positive, being 40 (5.2%) confirmed by the enzyme‐linked immunosorbent assay. Among the communities surveyed, we observed reactive cases in 15 of them, these cases being distributed, according to the age group, as follows: 1 case from 0 to 10 years; 13 cases from 11 to 60 years old; and 30 cases over 61 years. Conclusion The results indicate that Chagas’s disease remains with active transmission in the Campinas do Piaui city according to the occurrence of a case in a resident under 10 years of age. The region is endemic for Chagas’s disease, as observed by the high prevalence of positive cases.
