安徽省血吸虫病传染源控制策略研究Ⅱ河滩地区以传染源控制为主的综合防治措施预防血吸虫病效果

Study on effect for schistosomiasis japonicum control by synthetic measures with emphasis on infection source control in beach area

目的评价以传染源控制为主的综合防治措施预防血吸虫病的效果。方法在安徽省芜湖县河滩地区2个血吸虫病流行较严重的村(行春、腰埂)实施传染源控制、综合治理和卫生血防项目等综合防治措施,通过4年的措施实施观察其预防血吸虫痫效果情况。结果实施综合防治措施4年后,人群血吸虫感染率显著下降,2个试点村人群感染率分别由试点前(2006年)的3.95%、3.19%下降到试点后(2010年)的0.48%、0.41%,分别下降88.1%和87 1%;有螺环境感染螺密度及钉螺感染率均降为0,下降100%。结论河滩地区实施以传染源控制为主的综合防治措施可以有效消除感染性钉螺、控制人群感染,取得了很好的预防血吸虫病效果。

Objective To evaluate the effectiveness for schistosomiasis control by synthetic measures with emphasis on infectious source control.Methods 2 higher endemic villages in Wuhu County were selected to implement the synthetic measures of infectious sources control,environmental modification,and other preventive measures for schistosomiasis control.During the intervention period,the changes for the infection rate of humans and the infection rate of snails were observed.Results 4 years later,the schistosome infection rate of residents of two pilot villages reduced by 88.1%and 87.1%respectively,the density of infection snailsand the infection rate of snails reduced by 100%.Conclusion The synthetic measures with emphasis on infection source control were effective for schistosomiasis control in beach area.
