目的分析比较2005、2006年湖北省国家级血吸虫病监测点疫情,为制定全省防治策略提供科学依据。方法按《全国血吸虫病监测方案》的要求,开展16个监测点的监测工作,并将2年的监测结果进行比较。结果2005年和2006年16个监测点居民血吸虫感染率分别为1.71%和1.91%,2006年较2005年上升了11.69%;耕牛平均感染率分别为11.69%和12.06%,2006年与2005年相比上升了3.17%;活螺平均密度、感染性钉螺平均密度和钉螺感染率分别为0.850 0只/0.1 m2、0.002 5只/0.1 m2、0.29%和0.670 0只/0.1 m2、0.001 1只/0.1 m2、0.17%,2006年较2005年分别下降了21.45%、56.00%和41.59%。结论湖北省血吸虫病疫情较重,防治工作难度较大,仍然需要加大综合防治措施力度,认真落实各项防治措施。
Objective To analyze and compare the epidemic situation of national schistosomiasis surveillance points in Hubei Province in 2005 and 2006, and provide scientific evidence for the development of prevention and control strategies in the province. Methods According to the requirements of “National Schistosomiasis Surveillance Program”, the monitoring work of 16 monitoring points was carried out, and the results of 2 years of monitoring were compared. Results The prevalence rates of schistosomiasis among residents in 16 monitoring sites in 2005 and 2006 were 1.71% and 1.91% respectively, up by 11.69% in 2006 and 2005 respectively. The average infection rates of cattle were 11.69% and 12.06% respectively in 2006 and 2005 Compared with an average increase of 3.17%. The average density of live snails, the average density of infected snails and the infection rate of snails were 0.850 0 /0.1 m2,0.002 5 /0.1 m2,0.29% and 0.670 0 /0.1 m2,0.001 respectively /0.1 m2,0.17% respectively, down by 21.45%, 56.00% and 41.59% respectively over the previous year. Conclusion The epidemic situation of schistosomiasis in Hubei Province is heavy and its prevention and control work is more difficult. It is still necessary to intensify the comprehensive prevention and treatment measures and conscientiously implement various prevention and treatment measures.
