目的探索高邮市血吸虫病疫情变化规律,为湖沼型血吸虫病流行区防治工作提供科学依据。方法收集高邮市1970-2009年血吸虫病防治工作数据,对不同阶段血吸虫病防治与流行规律进行综合分析。结果在血吸虫病疫情控制(1970-1975年)、传播控制(1976-1994年)、传播阻断(1995-2009年)阶段的第1年,人群血吸虫病粪检阳性率分别为4.20%、0.80%、0,牛粪检阳性率分别为3.00%、0.51%、0。1984年人群粪检阳性率下降至0.04%,较1970年下降了99.05%。1970-1980年人畜血吸虫粪检阳性率呈显著正相关(r=0.67,P<0.05)。1985年后未查出当地感染的血吸虫病人和病牛。1970-2009年均未查出血吸虫感染性钉螺。结论高邮市在不同防治阶段坚持综合治理,虽有螺情反复,但血吸虫病疫情稳定下降,达到传播阻断标准。
Objective To explore the variation of schistosomiasis epidemics in Gaoyou and provide a scientific basis for the prevention and control of schistosomiasis lakes. Methods The data of prevention and treatment of schistosomiasis in Gaoyou from 1970 to 2009 were collected, and the prevention and treatment of schistosomiasis in different stages were comprehensively analyzed. Results In the first year of epidemic control of schistosomiasis (1970-1975), transmission control (1976-1994) and transmission blockage (1995-2009), the positive rates of fecal examination of schistosomiasis were 4.20% and 0.80 %, 0, cow dung seizure positive rates were 3. 00%, 0. 51%, 0. 1984, the total population of fecal examination decreased to 0.04%, compared with the decline of 1970, 99.05%. There was a significant positive correlation between the positive rate of schistosomiasis detection in 1970s and 1980 (r = 0.67, P <0.05). After 1985, the local infected schistosomiasis patients and diseased cattle were not detected. Schistosoma japonicum Infected Snails were not detected during 1970-2009. Conclusion Gaoyou City insisted on comprehensive management in different stages of prevention and treatment. Although there were repeated snail cases, the epidemic situation of schistosomiasis steadily declined and reached the standard of transmission block.
