Objective: To analyze the trend of visceral leishmaniasis incidence in China from 2004 to 2007.

The three provinces (autonomous region) with higher incidence were Xinjiang (occupying 47.5% of the total, 633/1,334), Gansu (33.2%, 443/1,334) and Sichuan (16.9%, 226/1,334). Cases distributed in all age groups, with the highest incidence in the group of under 10-year-old (51.3%). More cases occurred from March to August. Male to female ratio was 1.65:1. The number of counties with leishmaniasis cases increased from 43 in 2004 to 64 in 2007.
Conclusion: The endemic area of visceral leishmaniasis shows an increasing trend.
