目的探讨山丘地区实施以控制传染源为主的血吸虫病综合防治策略的效果和问题。方法 2006～2008年在荆门市血吸虫病疫区实施以控制传染源为主的综合防治策略,观察3年来的实施效果。结果 3年来,全市人群血吸虫感染率由0.24%上升到0.38%,钉螺面积由903.79万m2,上升到1701.02万/m2。结论山丘地区血吸虫感染率低,其传染源分散,用大量的投入来控制血吸虫病众多传染源中的部分(人、畜传染源)难度大,效果不明显,应因地制宜选择适当的控制策略。
Objective To explore the effects and problems of comprehensive prevention and control strategies for schistosomiasis in mountainous areas to control the source of infection. Methods From 2006 to 2008, a comprehensive prevention and control strategy was put forward to control the source of infection in schistosomiasis endemic areas of Jingmen City. The implementation effect in three years was observed. Results In the past three years, the prevalence of schistosomiasis in the whole city increased from 0.24% to 0.38%, and the snail area increased from 9,037,900 m2 to 17,010,200 m2. Conclusions In schistosomiasis, schistosomiasis infection rate is low and its sources of infection are scattered. It is difficult and ineffective to control some of the many sources of infection of schistosomiasis with lots of inputs. The appropriate control strategies should be chosen according to local conditions.
