目的分析2004~2007年云南省血吸虫病疫情,评价综合治理成效,为制定防控达标策略提供科学依据。方法根据《全国血吸虫病监测方案》和《云南省血吸虫病监测方案》,统计分析各项监测指标。结果疫情监测各项指标明显下降。2007年与2004年相比,急性血吸虫病人发病数下降94.74%,未发生暴发疫情,血吸虫病人得到治疗;校正后人群感染率下降86.72%;家畜粪检阳性率下降62.18%;钉螺面积由4316.4hm2压缩至2747.9hm2,阳性螺点数由771个减少至197个,阳性螺密度下降76.92%。结论通过4年来实施以控制传染源为主的综合治理措施,全省血吸虫病疫情得到了有效控制。
Objective To analyze the epidemic situation of schistosomiasis in Yunnan Province from 2004 to 2007 and evaluate the effectiveness of comprehensive treatment so as to provide a scientific basis for formulating the prevention and control standard. Methods According to “national schistosomiasis surveillance program” and “Yunnan schistosomiasis monitoring program”, statistical analysis of the monitoring indicators. Results The indicators of epidemic situation monitoring decreased significantly. Compared with 2004, the incidence of acute schistosomiasis patients dropped by 94.74% in 2007, no outbreaks were found and schistosomiasis patients were treated. After the correction, the infection rate in the population decreased by 86.72%; the positive rate of livestock droppings decreased by 62.18%; the snail area increased from 4316.4hm2 Compressed to 2747.9hm2, positive spiral points reduced from 771 to 197, the positive spiral density decreased 76.92%. Conclusion Through four years of comprehensive control measures focusing on controlling the source of infection, the epidemic situation of schistosomiasis in the province has been effectively controlled.
