目的探讨药物灭螺、兴林抑螺、吡喹酮化疗、健康教育等综合措施控制洞庭湖区费家湖地段血吸虫病防治效果。方法在费家湖的金星、富强两村,连续7年采用药物灭螺、兴林抑螺、化疗、健康教育等综合措施开展血吸虫病防治,动态监测钉螺密度、血吸虫感染情况以及血吸虫病人估算情况等。结果与防治工作初期的2003年相比,活螺平均密度下降了99.74%;居民感染率下降了95.04%;人群感染度下降了65.38%;估算病人数下降了94.93%。从2006年开始,钉螺感染率和感染螺平均密度就下降到0。7年间从暴发急性血吸虫病例数10例降低到0。结论费家湖地段血吸虫病疫情得到有效控制,综合措施对控制洞庭湖湖汊型血吸虫病复发现疫情有显著效果。
Objective To explore the control measures of schistosomiasis in Feijiahu section of Dongting Lake by comprehensive measures such as snail control of molluscicides, spirobatin, praziquantel and health education. Methods In schistosomiasis, Jinji and Fuqiang villages in Feijiahu, schistosomiasis control, dynamic monitoring of snail density, schistosomiasis infection and schistosomiasis estimation were carried out for seven consecutive years with comprehensive measures such as drug snail control, spirochete snail control, chemotherapy and health education Wait. Results The average density of live snails decreased by 99.74% compared with that in the early stage of prevention and treatment. The infection rate of residents decreased by 95.04%. The population infection rate decreased by 65.38%. The estimated number of patients dropped by 94.93%. From the beginning of 2006, the infection rates of snails and the average density of infected snails decreased to 0.7. The number of acute schistosomiasis cases dropped from 10 to 0 in seven years. Conclusion The epidemic situation of schistosomiasis in Feijiahu section is effectively controlled. The comprehensive measures have a significant effect on the control of the epidemic of the recovered schistosomiasis spp. In Dongting Lake.
