“…No Brasil, a doença distribui-se em vários estados, sua ocorrência depende basicamente da distribuição dos vetores domiciliados 4,5,6 . Minas Gerais foi um dos Estados brasileiros com maior prevalência da endemia chagásica, sendo, coincidentemente, onde a doença foi descoberta 7 .…”

In Minas Gerais State, Brazil, after the elimination of Triatoma infestans by the Brazilian Chagas Disease Control Program, some triatomine species, such as Panstrongylus megistus, have merited the attention of entomological surveillance authorities. After the decentralization of the Brazilian health system, certain administrative and operational difficulties have been observed in some municipalities (counties). This study aims to evaluate entomological surveillance for Chagas disease in the 54 municipalities supervised by the Division of Decentralized Health Activities in Divinopolis, Minas Gerais, from 2000 to 2003. In 46 municipalities, 1,531 triatomines were captured, of which 94.1% were P. megistus. The infection rate for T. cruzi in the vectors was 1.3%. A total of 850 reports were received and 835 site visits were conducted, showing that the program is active and efficient in the majority of the municipalities analyzed. The importance of the maintenance and improvement of entomological surveillance in the region was demonstrated, since triatomine bugs continue to invade (and can colonize) the domiciliary environment, although with low density.

“…It is estimated that approximately 100 million people remain exposed to the risk of infection 21 . The triatomine species of major epidemiological importance in Minas Gerais is Panstrongylus megistus, a species endemic to this region that presents a great capacity to invade and colonize houses and their peridomiciles 10 . In contrast, Triatoma infestans was introduced to this state via São Paulo in the early 20 th century and subsequently disseminated northwards 3 .…”

“…In contrast, Triatoma infestans was introduced to this state via São Paulo in the early 20 th century and subsequently disseminated northwards 3 . In 1940, Panstrongylus megistus was the triatomine species most often captured in Minas Gerais (79.8%), followed by Triatoma sordida (9.7%) and Triatoma infestans (9.3%) 10 . Although by that time Triatoma infestans was widely dispersed in southeastern Brazil, including the "Triângulo Mineiro" region, it was not recorded until 1950 in the north and northeast of Minas Gerais, which includes the Jequitinhonha Valley 14 15 .…”

This study aimed to evaluate the Chagas Disease Control Program which has operated since 1982 in the municipality of Berilo in the Jequitinhonha Valley, Minas Gerais, Brazil, based on evaluation of 5,242 domiciliary units (DUs) and 7,807 outbuildings over an eight-year period of epidemiological surveillance implanted in 1997. A total of 391 triatomines (280 Panstrongylus megistus and 111 Triatoma pseudomaculata) were captured, indicating the continued predominance of the former species. However, Triatoma pseudomaculata is clearly becoming more important in this region, with intradomiciliary colonies being detected in recent years. Entomological parameters, such as dispersion (17%) and intradomiciliary infestation (0.15%) indices, are compatible with the results of the epidemiological surveillance. The majority of DUs were of construction type A (plaster over bricks) or C (plaster over adobe). Twenty-five percent of the inhabitants of the DUs infested by triatomines were reactive in ELISA, IHA and IIF tests for Trypanosoma cruzi antigens. RESUMOO objetivo deste estudo foi avaliar o Programa de Controle de doença de Chagas instalado desde 1982 no município de Berilo, Vale do Jequitinhonha, MG, Brasil, baseado na avaliação de 5.242 unidades domiciliares e 7.807 anexos após oito anos de implantação da vigilância epidemiológica que ocorreu em 1997. Um total de 391 triatomíneos (280 Panstrongylus megistus e 111 Triatoma pseudomaculata) foram capturados, indicando o contínuo predomínio da primeira espécie. No entanto, Triatoma pseudomaculata está claramente se tornando mais importante nesta região, com colônias intradomiciliares sendo detectadas recentemente. Parâmetros entomológicos, como os índices de dispersão (17%) e infestação intradomiciliar (0,15%), são compatíveis com a fase de vigilância epidemiológica. A maioria das UDs apresenta padrão de construção tipo A (tijolo com reboco) e A maioria das UDs apresenta padrão de construção tipo A (tijolo com reboco) e C (adobe com reboco). Dentre os habitantes das unidades domiciliares infestadas por triatomíneos, 25% apresentavam testes reativos na ELISA, HAI e IFI para antígenos de Trypanosoma cruzi.

“…This is comparable to the results found by others authors in several Brazilian States 1 -5 13 -14 ll - 20 . In São Paulo State, FRÓES et al 10 found a higher prevalence rate in [10][11][12][13][14][15][16][17][18][19][20] age group and suggested that the disease in the Municipality of São José dos Campos, where the B. tenagophila is the intermediate host, was usually acquired during recreational activities. In Pedro de Toledo there was a decrease in the prevalence rates among individuals of 25 years and older (Figures 1 and 2).…”

SUMMARYDue to the scarce information about the epidemiological features of schistoso¬ miasis in which the vector is Biomphalaria tenagophila, an investigation was carried in Pedro de Toledo in 1980 where such peculiarity is observed. Stool examinations (Kato Katz method) were performed in 4,741 individuals (22.8% positive to Schistosoma mansoni eggs) of this 583 had previously received chemoterapy and 4,158 remainders, untreated. The schistosomiasis prevalence in those two groups where respectively 31.7% and 21.6% . Epidemiological investigation showed that 83.6% were autochthonous cases from the studied area: the autochthonous prevalence rate, and the intensity of infection in the untreated autochthonous cases were higher in males than in females; the intensity in the latter untreated group was low, 58.5 eggs/g feces {geometric mean). Moreover, according to the age groups the intensity of infections correlated well (r s = 0.745) with the prevalence rates. Schistosomiasis was veri¬ fied to occur mostly during the leisure time and by the use of water streams for housework in rural zone. Only 0.4% out of 1,137 snails was positive for S. mansoni cercariae, apparently unchanged from the 1978 study when the human prevalence was 12.0%. The studied area presented differences and similarities in relation to the other Brazilian areas were the main intermediate host is B. glabrata.
