[Analysis of schistosomiasis endemic situation in Jiujiang City, 2011]

To understand the endemic situation of schistosomiasis in Jiujiang City in 2011, so as to provide the evidence for decision-making of schistosomiasis control.

The epidemiological data of schistosomiasis in Jiujiang in 2011 were collected and analyzed with the descriptive epidemiology method.

By the end of 2011, there were 34974 cases of schistosomiasis in Jiujiang City, among them there were 2 326 advanced cases (106 cases were newly found in 2011), and no acute cases were found. About 24 454.78 hm2 of areas with Oncomelania snails were found in 2011, including 23 045.70 hm2 in marshland and lake regions (94.24%) and 1 409.08 hm2 in hilly region (5.76%). A total of 25 601 head of cattle were raised in schistosomiasis transmission regions in 2011, with a little increase comparing to that in 2010 (0.60%). The schistosome infection rate of cattle in 2011 (0.97%) decreased obviously comparing to that in 2010(3.52%). The chemotherapy coverage in cattle in 2011 (76.00%) increased significantly as compared to that in 2010 (50.85%) (P < 0.05).

The schistosomiasis endemic situation remains at a certain level in endemic areas of Jiujiang City. The number of domestic animals is large, so the pollution of environment still exists. Therefore, it is suggested that promoting the comprehensive schistosomiasis control strategy with emphasis on controlling sources of infection is an effective measure to achieve the mid and long term goals of schistosomiasis control program.
