目的分析太湖县血吸虫病传播阻断后疫情同升的原因.方法收集1995-2008年全县血吸虫病疫情统计资料和2004-2008年螺情调查及家畜检查基线资料,计算钉螺面积、感染螺面积、灭螺面积及人、畜感染率等指标,进行不同年份问的比较.结果 1995年查出有螺面积36.85 hm~2,其后连续8年发现钉螺扩散,至2008年底,有螺面积扩大至78.86 hm~2.1995-2008年共开展药物灭螺459.45 hm~2,灭螺覆盖率在12.39%～115.83%之间.1995年发生急性感染病例73例,人群感染率为2.06%,至2008年下降为0;耕牛感染率则由2004年的2.99%降至2008年的1.74%.结论因传染源持续存在、投入不足及水系灌溉影响,导致疫情反复,并出现螺情严重扩散,应加大防治力度,遏制疫情回升势头.

Objective To study the causes of schistosomiasis recurrence after transmission interruption in Taihu County.Methods Schistosomiasis epidemiological data of the whole county during 1995-2008 and the baseline data of snail survey and cattle examination in 2004-2008 were collected and analyzed retrospectively.The areas of snails and the infected snails,the areas of snail control and the infection rate of humans and animals were calculated,and compared among different years.Results The areas with snails spread from 36.85 hm~2 to 78.86 hm~2 in 1995-2008.During 1995-2008 molluscicidal treatment covered 459.45 hm~2,the coverage rate was 12.39%-115.83%.In 1995 there were 73 cases of acute infection,human infection rate was 2.06%,then 2008 dropped to 0,while the cattle prevalence rate was 2.99% in 2004,dropped to 1.74% in 2008.Conclusions Persistent source of infection,lack of financial support and the impact of irrigation resulted in endemic recurrence and serious spread of snails.Prevention efforts should be intensified to control the endemic recurrence.
