【 摘 要 】

This study aimed to demonstrate the geographical expansion of visceral leishmaniasis in Pernambuco State, Brazil. With data on the number of visceral leishmaniasis cases notified from 1990 to 2001, maps showing the biannual evolution of the geographical distribution of the disease per municipality were elaborated. A map of the cumulative geographical distribution of the cases registered during the whole period was also constructed. From 1990 to 2001, 1,737 cases of visceral leishmaniasis were notified in Pernambuco. In 1990, 15.2% (n = 28) of the municipalities notified cases of the disease. In contrast, this percentage increased to 78.3% (n = 144), over an eleven-year period. The map of cumulative geographical distribution during the whole period shows a notable concentration of cases in Agreste and Sertão. A notable geographical expansion of visceral leishmaniasis in Pernambuco also occurred, probably reflecting the low impact of the current control measures and, possibly, an improvement in the notification system.
