摘要
目的探讨江苏省句容市血吸虫病传播控制后的防治效果，为进一步做好血吸虫病预防控制工作提供科学依据。方法对2005—2010年句容市药物灭螺、环境改造灭螺及血吸虫病健康教育结果进行统计分析，纵向观察钉螺面积、人群血吸虫阳性检出率、血吸虫病防治知识知晓率的变化，研究灭螺覆盖率与钉螺面积、居民阳性检出率的相关性。结果2005—2010年连续6年未查出感染性钉螺，钉螺面积、活螺密度逐年下降。居民血吸虫阳性检出率从2005年的O．34％（36／10 551）下降到2010年的0．00％（0／12372），学生和居民血吸虫病防治知识知晓率分别由2005年的88．28％（128／145）和86．44％（204／236）提高到2010年的96．58％（141／146）和92．83％（246／265）。钉螺面积与药物灭螺覆盖率呈显著负相关（r=-0．910，P〈0．05），与环境改造灭螺覆盖率无显著相关关系（r=-0．404，P〉0．05）；居民阳性检出率与药物灭螺覆盖率和环境改造灭螺覆盖率均无显著相关关系（r值分别为0．107、-0．496，P均〉0．05）。结论句容市钉螺面积逐年下降，居民血吸虫病阳性检出率维持在较低水平，采取控制钉螺、人群筛查化疗、血吸虫病防治健康教育为主的综合性防治策略效果明显。
Objective To investigate the effect of measures on controlling of schistosomiasis in Jurong city Jiangsu province and provide a scientific basis for doing a better job in prevention and control of schistosomiasis. Methods Monitoring data from 2005 to 2010 was analyzed, including the effect of spraying drugs, changing environment, coupled with health education measures in eradicating oncomelania. Oncomelania areas, positive detection rate of schistosomiasis, and the awareness rates of prevention knowledge of schistosome were observed longitudinally. Correlation of coverage rate of snail controlling and resident positive rate of schistosomiasis was studied. Results There were no infected snails from 2005 to 2010. The densities of living snails and areas with snails decreased year by year. Residents＇ positive detection rate of schistosomiasis decreased from 0.34%（36/10 551 ） to 0.00%（0/12 372） from 2005 to 2010. The rates of students, and citizens＇ knowledge of schistosome on prevention of the disease increased from 88.28% （128/145） and 86.44% （204/236） to 96.58%（141/146） and 92.83% （246/265） from 2005 to 2010, respectively. There was a negative correlation between oncomelania areas and drug coverage areas（r = - 0.910, P 〈 0.05）; there was no correlation between oncomelania areas and coverage rate of snail control by environmental modification （r = - 0.404, P 〉 0.05）; there was no correlation between positive rate of schistosomiasis in resident and coverage rate of snail control with molluscisides, and coverage rate of snail control by environmental modification （r = 0.107, - 0.496, all P 〉 0.05）. Conclusions Snails areas in Jurong city is decreased year by year. Residents＇ positive detection rate of schistosomiasis infection is maintained at a low level. The effects of oncomelania-controlling, health education, and chemotherapy are remarkable.
