Abstract:
Objective To understand the endemic situation of schistosomiasis among 80 national surveillance sites for schistosomiasis in 2006,so as to provide scientific evidence for making out schistosomiasis prevention and control measures. Methods According to the national surveillance protocol, the endemic situation of schistosomiasis in residents and livestock, and the status of Oncomelania snails and other factors were investigated in the 80 national surveillance sites for schistosomiasis, and all the data were collected and analysed. Results Among the 80 national surveillance sites,the average positive rate of residents with sera examination was 13.60% and the average positive rate with stool examination was 1.59%.The average positive rate of floating population with sera examination was 5.79%. There were 143 advanced patients among the national surveillance sites, and 12 acute patients were reported in 2006, but no breaking-out epidemic reported. The proportion of domestic animals stable breeding were about 4.74% of 5 365 examined animals in 2006, and the others were not.The infection rate of domestic animals was 5.93% that declined by 34.49% compared with that in 2005 and especially for the infection rate of cattle and sheep. A total of 7 429.63 hm2 of areas were surveyed. The areas of snail habitats, infected snail habitats and the new snail habitats were 4 994.01,621.75 hm2 and 21.75 hm2,respectively. The density of living snails and infection rate of snails were 0.544 8/0.1 m2 and 0.37%, which increased compared with infection rate of 0.26% in 2005. Conclusion The endemic situation of residents, cattle and snail habitats declined in 2006 compared with those in 2005 in the national surveillance sites.
