Abstract

Objective: To evaluate the actual effect of the schistosomiasis control program in Jiangsu Province from 2010 to 2015.

Methods: A total of 67 schistosomiasis-endemic counties in 10 cities were selected, and a combination of retrospective investigation and on-site investigation was adopted to collect and record the epidemic data of the counties from 2010 to 2015, and a retrospective survey database of epidemic situation was established. The effects of integrated control strategies with both Oncomelania hupensis snail control and infection source control were evaluated.

Results: From 2010 to 2015, 2 465 911 persons who lived in endemic areas were detected for schistosomiasis, with 16 974 positive cases of blood examinations, and 8 positive cases of fecal examinations. Totally 5 145 people with advanced schistosomiasis were treated and 40 460 people with the history of schistosome cercarial-infested water contact received the expanded chemotherapy. A total of 127 636 cattle raised in the endemic areas were detected, and 51 619 cattle (head-times) with the history of cercarial-infested water contact also received the expanded chemotherapy. The area with snails control by molluscicides was 18 604.84 hm2. By the end of 2015, schistosomeinfected snails had not been found and there was no zoological schistosome infection for 5 consecutive years, and in addition, there had been no acute schistosome-infected persons for 6 consecutive years in the whole province. The area with snails dropped to 1 977.18 hm2, with a decreasing rate of 55.24% compared with that in 2010.

Conclusions: After the implementation of the plan for the prevention and control of schistosomiasis in Jiangsu Province (2010-2015), the prevention and control of schistosomiasis has achieved remarkable effects and realized the goal of the plan.

[摘要] 目的评估《江苏省血吸虫病防治规划纲要 (2010–2015 年) 》实施效果。方法 选择江苏省 10 个设区市的 67 个血吸虫病流行县 (市、区), 采取回顾性调查方法, 以县 (市、区) 为单位收集 2010–2015 年血吸虫病疫情和防治工作等资 料建立数据库, 并对防治效果进行评估。结果 2010–2015 年, 江苏省累计完成人群血吸虫病查病 2 465 911 人·次, 累计 查出血检阳性 16 974 人·次、粪检阳性 8 人, 治疗晚期血吸虫病 5 145 人·次, 扩大化疗 40 460 人·次; 开展家畜查病 127 636 头·次, 家畜扩大化疗 51 619 头·次; 开展药物灭螺 18 604.84 hm2。至 2015 年底, 全省已连续 5 年未发现血吸虫感染性钉 螺和家畜血吸虫感染, 连续 6 年未发生本地急性血吸虫感染; 钉螺分布面积下降至 1 977.18 hm2, 较 2010 年下降了 55.24%。结论《江苏省血吸虫病防治规划纲要 (2010–2015 年) 》实施后, 全省血吸虫病防治工作取得了显著成效, 实现 了各项防治规划的目标。.
