[General situation and perspectives of chagas disease in Northeastern Region, Brazil].
Primary and secondary data show the importance and distribution of human Chagas disease (HCD) in Northeast Brazil. Among the 27 detected vector species, Triatoma infestans, Panstrongylus megistus, Triatoma brasiliensis and Triatoma pseudomaculata are epidemiologically important. Major medical impact is attributed to T. infestans and P. megistus, the most domiciliated and vulnerable species, while the other two are native and more difficult to control. Regional differences in transmission and medical impact of HCD exist in the Northeast, where in general the disease appears to be less harmful than in other Brazilian regions like the Southeast and State of Goiás. There is a downward trend in HCD transmission and morbidity in the Northeast, its control in the region is a cause of concern because of the decommissioning of the National Health Foundation without a corresponding assimilation of its routine activities by regional and municipal institutions.
