Abstract
To assess the effect of removing leishmania-infected dogs on the incidence of visceral leishmaniasis, a controlled inter vention study was performed in northeast Brazil. The attempted elimination of seropositive dogs resulted in an initial significant decrease in the annual incidence of seroconversion among dogs from 36% to 6%over the first two years. In the following rwo years, the incidence increased to 11% and 14%, respectively. In a control area in which dogs were surveyed but seropositive dogs werw not removed, the cumulative incidence did not vary significantly from year to year, ranging from 16% to 27%. In the intervention area, the prevalence of dog seropositivity decreased from 36% before the intervention to 10% and remained stable.
