O inquérito nacional de soroprevalência de avaliação do controle da doença de Chagas no Brasil (2001-2008)

Abstract: Um inquérito de soroprevalência de doença de Chagas foi realizado em amostra representativa da população com idade até cinco anos de toda a área rural brasileira, exceto o Estado do Rio de Janeiro. Foram estudadas 104.954 crianças, que tiveram amostras de sangue coletadas em papel de filtro e submetidas a testes de screening pelas técnicas de imunofluorescência indireta (IFI) e ELISA em um único laboratório. Todas as amostras com resultados positivos ou indeterminados, juntamente com 10% daquelas com resultado… Show more

“…This study was the first to identify regional differences in the congenital transmission of Chagas disease in Brazil, possibly related to the existence of T. cruzi TcV and TcVI (101) . Moreover, it points to the absence of Chagas disease transmission by a sustained domiciliary vector in the country (39) (101) .…”

“…In the other 11 (0.01%) cases, only the child tested positive, indicating probable vector transmission [derived from the State of Piauí (2), Ceará (2), Paraíba (2), Alagoas (2), Rio Grande do Norte (1), Amazon (1) and Paraná (1)].

“…All the blood samples on the filter paper were eluted in 250 µL of phosphate-buffered saline (pH 7.2) and were tested using the IIF test, as recommended by Fife and Muschel ( 1959 ) and Souza and Camargo ( 1966 ), as adapted by Ostermayer et al ( 2011 ) for the detection of anti- T. cruzi antibodies. The IIF-Chagas kit produced by Biomanguinhos was used.…”
