To evaluate the mid-term effectiveness of the medium-and-long-term programme for prevention and control of schistosomiasis in Anhui Province.
In the programme, the comprehensive measures were carried out, including the schistosomiasis detection and chemotherapy for residents and livestock, snail control, health education, and infectious source control. The mid-term effectiveness of the programme was observed and evaluated longitudinally.
From 2004 to 2009, 750 798 schistosomiasis patients and 547 069 persons with the history of infested water contacting were treated. The number of positive cattle treated was 8 462 cattle-times and the number of cattle with history of infested water contact treated was 117 023 cattle-times. The area with snails control by molluscicides was 30 532.0 hm2, and the area with snails control by environmental modification was 13 979.5 hm2. The number of persons who received health education was 31.73 million person-times. The infectious source control measures were carried out in 40% of endemic villages with human infection rate being more than 1%. Up to 2009, the infection rates of population and cattle, and the incidence rate of acute schistosomiasis reduced to 0.51%, 1.25% and 0.30/100 000, respectively. During the period of 2004-2009, the areas with snails fluctuated from 29 065.4 to 29 740.3 hm2. The densities of living snails and infected snails both showed a declining trend in general. During these years, the whole province reached the criteria of infection control, 4 counties reached the criteria of transmission control, and 4 counties reached the criteria of transmission interruption.
The effect of the comprehensive strategy of schistosomiasis control is remarkable.
评估安徽省血吸虫病中长期防治规划的中期效果。
该规划实施了综合防治措施，包括居民和家畜血吸虫病查治、灭螺、健康教育以及传染源控制等。对该规划的中期效果进行纵向观察与评价。
2004年至2009年，共治疗血吸虫病患者750798例，有疫水接触史者547069人。治疗阳性病牛8462头次，有疫水接触史牛117023头次。药物灭螺面积30532.0公顷，环境改造灭螺面积13979.5公顷。接受健康教育人数达3173万人次。在人群感染率大于1%的40%的流行村实施了传染源控制措施。至2009年，人群感染率、家畜感染率及急性血吸虫病发病率分别降至0.51%、1.25%和0.30/10万。2004 - 2009年，钉螺面积在29065.4至29740.3公顷之间波动，活螺密度和感染螺密度总体呈下降趋势。期间全省达到疫情控制标准，4个县达到传播控制标准，4个县达到传播阻断标准。
血吸虫病综合防治策略效果显著。
