[Visceral leishmaniasis in China during 2004-2007].
OBJECTIVE
To analyze the trend of visceral leishmaniasis incidence in China from 2004 to 2007.


METHODS
Data of leishmaniasis in 2004-2007 were collected from the National Web-Based Infectious Diseases Report System, and statistically analyzed by using SPSS 12.0 software.


RESULTS
A total of 1,334 leishmaniasis cases was reported in the 4 years. 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.


CONCLUSIONS
The endemic area of visceral leishmaniasis shows an increasing trend.
