目的了解目平湖地区五一村血吸虫病流行动态,为洞庭湖洲垸亚型流行区制定血吸虫病防治对策提供科学依据。方法收集2002-2010年五一村血吸虫病情、螺情、人口和社会经济数据,以及实施的各种防治措施等资料,分析五一村血吸虫病疫情指标的动态演变规律。结果五一村居民血吸虫感染率逐年下降,由2002年的11.44%降至2010年的1.12%,其中男性感染率高于女性,职业以渔民感染率最高。9年间耕牛粪检阳性率维持在10%左右。垸外钉螺密度大幅度下降,由2003年秋季最高的10.49只/0.1 m2降至2010年秋季的0.68只/0.1 m2。2003年垸外春季感染螺平均密度高达0.026只/0.1 m2,2006年以后再未查到感染性钉螺。结论五一村血吸虫病疫情大幅度下降,耕牛和渔民是今后防治工作的重点。
Objective To understand the prevalence of schistosomiasis in Wuyi Village, the Guping Lake region and provide a scientific basis for the development of schistosomiasis control strategies in embankment endemic areas of Dongting Lake. Methods The data of schistosomiasis, snail, population and socio-economic data in Wuyi Village from 2002 to 2010 were collected and various control measures were implemented. The dynamic evolution of schistosomiasis in Wuyi Village was analyzed. Results The prevalence of schistosomiasis among residents in Wuyi village dropped year by year from 11.44% in 2002 to 1.12% in 2010. Among them, the infection rate of males was higher than that of females, and the occupational rate was the highest among fishermen. 9-year cow dung seized positive rate remained at about 10%. The density of snails outside the embankment dropped significantly from the highest of 10.49 /0.1 m2 in the autumn of 2003 to 0.68 /0.1 m2 in the autumn of 2010. In 2003, the average annual cumulative value of 0.026 aquatic organisms /0.1 m2, after 2006 Infected snails were not found again. Conclusion The epidemic situation of schistosomiasis in Wuyi village has been greatly reduced. Cattle and fishermen are the focus of prevention and treatment in future.
