Abstract in Portuguese
As of 1979, data gathered by the Chagas' Disease Control Program (CDCP) in the Brazilian state of Minas Gerais indicated that Triatoma infestans was the Chagas' disease vector most commonly found in and around human dwellings. A decade later, however, this picture had changed, presumably as a result of control efforts; few specimens of T. infestans were collected; and Triatoma sordida had become the most commonly collected vector insect. The aim of the work reported here was to assess the effectiveness of the CDCP in Minas Gerais in 1979-1989, with special reference to T. sordida. For this purpose, 1979-1989 triatomine collection data were reviewed for the two Minas Gerais health districts (Montes Claros and Uberaba) believed to have the heaviest T. sordida infestations. In addition, 1987 data from a serologic survey for human Trypanosoma cruzi infections in seven municipalities of these regions were compared with earlier (1978) serologic data from the same locales. In general, the triatomine collection data documented the precipitous decline of T. infestans in and around human dwellings. They also indicated that while the T. sordida collections had remained stable (in Uberaba) or increased markedly (in Montes Claros), there had been no great upsurge in the numbers of T. sordida collected inside dwellings. It was concluded that control measures were preventing extensive house reinfestations in both Montes Claros and Uberaba; that the situation in Uberaba was relatively stable; and that the marked increase in T. sordida populations around homes in Montes Claros was associated with forest clearing and changing settlement patterns.
