目的掌握湖北省血吸虫病疫情变化情况,为制定防治规划提供科学依据。方法按照《湖北省血吸虫病监测方案》的要求,在全省血吸虫病流行区选择有代表性的74个流行村作为监测点,开展人畜查病和钉螺调查。结果 2006~2008年监测点居民血吸虫感染率分别为2.77%、1.97%和1.32%,耕牛感染率分别为8.83%、5.85%和1.85%,活螺平均密度分别为0.73、0.47和0.37只/0.1m2,感染螺平均密度分别为0.002 0、0.000 5和0.000 3只/0.1m2,钉螺感染率分别为0.27%、0.11%和0.08%。疫情逐年下降,2008年和2006年相比,居民血吸虫感染率、耕牛感染率、活螺平均密度、感染螺平均密度、钉螺感染率分别下降52.35%、79.05%、49.32%、85.00%和70.37%。结论 2006~2008年湖北省血吸虫病疫情呈明显下降趋势,但疫情并不稳定,反弹因素依然存在,疫情进一步下降的难度加大,为确保2013年全省达到血吸虫病传播控制目标的实现,必须重点加强耕牛的管理与处置,加强查螺和灭阳性螺的工作,切实控制传染源。
Objective To investigate the epidemic situation of schistosomiasis in Hubei Province and provide a scientific basis for making prevention and control plan. Methods According to the requirements of “schistosomiasis monitoring program in Hubei Province”, 74 representative endemic villages were selected as monitoring points in the endemic areas of schistosomiasis in the province to carry out the investigation of snails and snails. Results The infection rates of resident schistosomiasis were 2.77%, 1.97% and 1.32% respectively at 2006 to 2008, and the rates of cattle infection were 8.83%, 5.85% and 1.85% respectively. The mean average density of live snails was 0.73, 0.47 and 0.37 / 0.1m2. The mean density of infected snails was 0.002 0, 0.0005 and 0.000 3 /0.1m2 respectively, and the infection rates of snails were 0.27%, 0.11% and 0.08%, respectively. Compared with 2006, the infection rate of schistosomiasis, the rate of cattle infection, the average density of live snails, the average density of infected snails and the infection rate of snails decreased by 52.35%, 79.05%, 49.32%, 85.00% and 70.37, respectively %. Conclusion The epidemic situation of schistosomiasis in Hubei Province showed a declining trend from 2006 to 2008, but the epidemic situation was not stable. The rebound factor still existed and it was more difficult to further reduce the epidemic situation. To ensure the achievement of the goal of schistosomiasis control in 2013, Emphasis will be placed on strengthening the management and disposal of cattle, strengthening the work of snailing and snailing, and effectively controlling sources of infection.
