目的评价长江武汉段铁板洲以平整滩地、翻耕种植为主的综合防治措施控制血吸虫病的效果。方法2011-2015年,在综合防治前后,每年春季均在铁板洲进行螺情调查,并对洲滩相邻的花园社区6~65岁居民进行病情调查;2014年7月下旬开展哨鼠监测。此外,对综合开发治理后的经济效益进行评价。结果 2011年综合治理前人群感染率为0.72%(3/414),2012年综合开发后人群感染率为0.37%(2/536),2013年降为0.31%(1/326),2014、2015年未再查出血吸虫病病人。与2011年相比,2015年铁板洲有螺面积下降了22.18%,有螺框出现率下降了97.83%,活螺平均密度下降了98.25%,各年均未发现感染性钉螺。哨鼠监测未发现阳性哨鼠。与综合治理前相比,铁板洲治理后每年净收入增加233.33%。结论铁板洲实施农业综合治理后血吸虫病病情及螺情均显著下降,经济效益和社会效益显著。
Objective To evaluate the effect of controlling schistosomiasis by comprehensive prevention and control measures of flat beach land and tillage cultivation in Tieban Island of Wuhan section of the Yangtze River. Methods From 2011 to 2015, before and after the comprehensive prevention and control, the investigation was conducted in the spring of each year in the state of Iron Panch continent and the residents aged 6 to 65 in the garden community adjacent to Chau Beach were surveyed. In the end of July 2014, . In addition, the economic benefits after comprehensive development and management are evaluated. Results The infection rate before comprehensive treatment in 2011 was 0.72% (3/414). The overall infection rate after integrated development was 0.37% (2/536) in 2012, 0.31% (1/326) in 2013, No further detection of schistosomiasis patients. Compared with 2011, there was a decrease of 22.18% in the area of conch in the state of Iron Island, a decrease of 97.83% in the occurrence of snail boxes and a decrease of 98.25% in average density of live snails. No infectious snails were found in any year. No positive sentinel mice were detected in the sentinel surveillance. Compared with the pre-integrated management, the annual net income after the management of Tie-Pan increased by 233.33%. Conclusion The status and snail of schistosomiasis in Tiepan after the comprehensive management of agriculture were significantly decreased, with significant economic and social benefits.
