Fig. 2: annual number of hospital internments due to Chagas disease in Brazil, 1984-1997. Note how the number of hospitalisations declines in the period of the national vector control programme (1983-1986) then rises as this programme was suspended in response to the demand of new dengue epidemics. But from the launch of the new vector control interventions with the Southern Cone Initiative, in 1991, there has been a steady decline in the number of hospitalisations (data from Ministry of Health, Brasília, Brazil).
