目的对江陵县血吸虫病疫情进行分析,掌握血吸虫病流行趋势。方法收集2004-2013年江陵县血吸虫病疫情资料,对人群、耕牛病情和钉螺情况等进行分析,计算人和耕牛血吸虫感染率、钉螺感染率等疫情指标。结果人群血吸虫感染率由2004年的10.22%下降到2013年的0.63%,下降幅度为93.84%。其中,2009-2013年人群血吸虫感染率的下降幅度较大,为76.92%。耕牛感染率呈总体下降趋势,由2004年的7.59%下降至2013年的0,下降了100%。活螺框出现率和钉螺感染率分别下降了17.53%、100%。结论通过10年防治,江陵县血吸虫病疫情已整体处于较低水平,但依然存在传播风险,应继续加强实施以血吸虫病传染源控制为主的综合防治策略。
Objective To analyze the epidemic situation of schistosomiasis in Jiangling County and learn the epidemic trend of schistosomiasis. Methods The epidemic data of schistosomiasis in Jiangling County from 2004 to 2013 were collected. The population, the condition of cattle and snail infection were analyzed. The epidemic indexes of schistosomiasis infection and snail infection were calculated. Results The prevalence of schistosomiasis in the population declined from 10.22% in 2004 to 0.63% in 2013, a decrease of 93.84%. Among them, the rate of decline of human infection rate in 2009-2013 was 76.92%. Cattle infection rate showed an overall downward trend, falling from 7.59% in 2004 to 0 in 2013, a decrease of 100%. The incidence of live screw and snail infection decreased by 17.53% and 100% respectively. Conclusion After 10 years of prevention and treatment, the epidemic situation of schistosomiasis in Jiangling County has been at a low level as a whole. However, there is still a risk of transmission and a comprehensive prevention and control strategy based on infection source control of schistosomiasis should be further strengthened.
