目的掌握湖北省2012年血吸虫病监测点疫情。方法按照《湖北省血吸虫病监测方案》要求,在全省血吸虫病流行区选择具有代表性的207个流行村作为监测点,开展人畜查病和钉螺调查。结果 207个监测点人群血吸虫感染率为0.55%,50~岁和60~岁年龄组人群感染率分别为0.92%和0.90%,高于其他年龄组;牧民、渔民、农民和船民感染率分别为1.37%、0.72%、0.67%,0.67%,高于其他职业人群感染率。耕牛血吸虫感染率为0.38%。活螺平均密度为0.367 49只/0.11 m2,感染螺平均密度为0.000 016只/0.11 m2,钉螺感染率为0.004 2%。结论与2011年相比,2012年湖北省血吸虫病疫情明显下降,但是仍需加大家畜传染源控制措施的实施力度,同时加强重点人群健康教育。
Objective To master the epidemic situation of schistosomiasis surveillance in Hubei Province in 2012. Methods According to the requirements of “schistosomiasis surveillance program in Hubei Province”, 207 endemic villages were selected as monitoring sites in the endemic areas of schistosomiasis in the province to carry out the investigation of snails and snails. Results The prevalence of schistosomiasis was 0.55% in 207 monitoring sites and 0.92% and 0.90% respectively in 50- and 60-year-old age groups, which were higher than other age groups. The infection rates of herdsmen, fishermen, farmers and boat people were 1.37%, 0.72%, 0.67%, 0.67%, higher than other occupational infection rates. Cattle schistosome infection rate was 0.38%. The mean density of live snails was 0.367 49 / 0.11 m2, the mean density of infected snails was 0.000 016 /0.11 m2, and the infection rate of snails was 0.004 2%. Conclusion Compared with 2011, the epidemic situation of schistosomiasis in Hubei Province decreased significantly in 2012, but it still needs to step up the implementation of control measures of livestock sources of infection and strengthen the health education of key populations.
