目的评价山丘型地区阻断血吸虫病传播综合措施效果。方法收集2004-2014年句容市血吸虫病综合防治和疫情资料,评价防治效果。结果 2004-2014年,句容市钉螺面积、活螺密度分别自43.13 hm2、1.48只/0.1 m2下降至0;居民血吸虫病血清学阳性率持续下降;居民和学生的血防健康教育知晓率分别自88.43%、82.04%提高到92.56%、95.74%;钉螺面积与灭螺覆盖率呈显著负相关(r=-0.864,P<0.05)。结论山丘型地区坚持灭螺和化疗为主的血吸虫病综合措施可使血吸虫病疫情快速、稳定下降,从而推进了血吸虫病传播阻断目标的实现。
Objective To evaluate the effectiveness of comprehensive measures to prevent the spread of schistosomiasis in hillside areas. Methods The data of comprehensive prevention, treatment and epidemic situation of schistosomiasis in Jurong from 2004 to 2014 were collected to evaluate the control effect. Results From 2004 to 2014, the snail area and live spiral density in Jurong dropped from 43.13 hm2 and 1.48 /0.1 m2 to 0, respectively. The serological positive rate of residents with schistosomiasis continued to decline. The awareness rates of health education among residents and students were respectively 88.43%, 82.04% to 92.56% and 95.74%, respectively. There was a significant negative correlation between snail area and snail coverage (r = -0.864, P <0.05). Conclusion The comprehensive measures of schistosomiasis insisted on snail-killing and chemotherapy-based in hillside area can make the epidemic of schistosomiasis rapidly and steadily decline, thus promoting the realization of the target of blocking schistosomiasis transmission.
