Resumo
This study aims at assessing the risk of Chagas disease transmission in two risk endemic Municipalities after the local implementation of Triatoma infestans Eradication Program (PETI). To that end, a epidemiological, entomological and serological assessment of PETI was carried out in loco in the Municipalities researched. In the epidemiological context of Chagas disease, according to serological investigation conducted in 1980, seroprevalence amongst the population researched was around 0,82% in São Luís dos Montes Belos (SLMB) and 2,35% in Novo Brasil (NB). At present, a serological survey is underway in the region. In the first stage of serological investigation, about to be concluded, samples from 103 children residing in Novo Brasil rural area and from 303 children residing in São Luís dos Montes Belos rural area were collected on filter paper, and the results were negative; later, 60 test-tube samples were collected in both Municipalities for performing more specific techniques. The domiciliary infestation index in SLMB (rural area) raised from 8,80% to 10,6% (2004-2005), and from 0,84% (2004) to 0,39% (January-July 2005) in NB (rural area). The population under contagion risk is around 4109 inhabitants in SLMB and 1153 inhabitants in NB, due to the presence of vectors. Endemic zones are concentrated in rural area, where potential vectors such as Triatoma sordida are found (around 90% of the species captured in SLMB and 50% in NB in 2005). Health education is jointly conducted in São Luís dos Montes Belos and Novo Brasil by the National Health Foundation (FUNASA), the Family Health Program (PSF) and both Municipal Secretariats of Education, by means of expositions, consultations and the Minimum Surveillance Unit (UMV), which is also applied in the indoor detection of traces of Triatominae. In conclusion, the control
of Chagas disease transmission lies on the joint effects of seroepidemiological surveillance, continuous sprinkling of residual insecticides and the implementation of housing improvement program in endemic areas, as well as the continuance and strengthening of Health Education efforts through Family Health Program (PSF).
