湖北省2009-2010年国家级监测点血吸虫病疫情监测报告

Monitor of schistosomiasis endemic situation in national surveillance sites of Hubei Province(2009-2010)

目的分析湖北省2009-2010年国家级血吸虫病疫情监测点监测结果,为制定血吸虫病防治对策提供科学依据。方法依照《全国血吸虫病监测方案操作手册》,开展16个监测点的监测工作,并将两年的各项指标进行统计分析。结果 2009-2010年16个监测点居民血吸虫感染率分别为1.03%和0.89%,2010年与2009年相比下降了13.59%,不同职业居民感染率以渔民最高;耕牛平均感染率分别为1.98%和1.41%,2010年与2009年相比较下降了28.79%;2010年感染性钉螺平均密度和钉螺感染率与2009年相比,分别下降了53.66%和57.55%,2010年活螺平均密度较2009年上升了10.43%。结论 监测点人、畜血吸虫感染率呈现持续下降,但少数监测点钉螺感染率仍较高,应加强查灭螺等综合防治措施。

Objective To identify the schistosomiasis situation of Hubei province in 2009-2010,so as to provide evidence for schistosomiasis contro1.Methods The surveillance was carried out in 16 national surveillance sites of Hubei Province according to the national surveillance protocol.Data of the two years were analyzed.Results In the 16 national surveillance sites in 2009 and 2010,the infection rate of residents was 1.03% and 0.89% respectively.As compared with 2009,it dropped 13.59% in 2010.Fisherman had the highest infection rate among all the professionals.The average infection rate of cattle was 1.98% and 1.41% respectively.The density of infected snails and the snail infection rate descended obviously,which were 53.66% and 57.55% respectively.In 2010 the live average density had an increase of 10.43%,as compared with that in 2009. Conclusions In the surveillance sites the infection rate of both human and cattle dropped persistently,however,in a few surveillance sites the infection rate of snails remained high.Therefore,it is necessary to strengthen snail control,and promote the effect of snail eradication.
