[The spread of the visceral leishmaniasis epidemic in the State of Mato Grosso, 1998-2005].
An epidemic of visceral leishmaniasis began in 1998, in the Metropolitan Region of Cuiabá, the capital of the State of Mato Grosso, Brazil. Today, it has reached 34 (24.1%) of the 141 municipalities in the state. Between January 1998 and December 2005, 138 autochthonous cases were notified, mainly in males (58%), children aged 0-9 years (51.5%) and inhabitants of urban areas (66.7%). Canine visceral leishmaniasis has been detected in 41 municipalities, with positive serum in 9% of the 40,000 dogs examined. Lutzomyia longipalpis and/or Lutzomyia cruzi were captured in 14 out of the 18 municipalities that simultaneously recorded both human and canine visceral leishmaniasis. These findings indicate that visceral leishmaniasis transmission has become disseminated throughout the state, following migratory flows and the process of disorderly occupation of urban areas. The presence of Lutzomyia cruzi alone in areas with high incidence of human and canine cases suggests possible participation by this species in the transmission chain for visceral leishmaniasis in Mato Grosso.
