目的掌握2008-2012年绵阳市血吸虫病疫情和流行趋势变化规律,为科学制定血吸虫病防治策略提供依据。方法收集2008-2012年绵阳市血吸虫病疫情资料进行分析。结果全市6个血吸虫病流行县中有3个已达国家血吸虫病传播阻断标准,另3个县达到国家血吸虫病传播控制标准。2008-2012年人群血吸虫感染率分别为0.15%、0.02%、0.01%、0.00%和0.00%,无急性血吸虫病病例报告;家畜血吸虫感染率分别为0.23%、0.29%、0.22%、0.00%和0.00%。钉螺面积逐年下降,未查见感染性钉螺。结论绵阳市血吸虫病疫情总体上已趋于低度流行状态,但仍有反复徘徊的可能,应加强巩固监测工作。
Objective To understand the regularity of the epidemic situation and epidemic trend of schistosomiasis in Mianyang City from 2008 to 2012 and provide the basis for the scientific development of schistosomiasis control strategy. Methods The data of epidemic situation of schistosomiasis in Mianyang from 2008 to 2012 were collected for analysis. Results Three of the six schistosomiasis endemic counties in the city had reached the national schistosomiasis transmission block standard, and the other three counties reached the national schistosomiasis transmission control standard. The infection rates of schistosomiasis were 0.15%, 0.02%, 0.01%, 0.00% and 0.00% respectively from 2008 to 2012, and no cases of acute schistosomiasis were reported. The infection rates of schistosomiasis were 0.23%, 0.29%, 0.22% and 0.00% 0.00%. Snail area decreased year by year, not found infectious snails. Conclusion The overall epidemic situation of schistosomiasis in Mianyang City has tended to be low prevalence, but there is still the possibility of repeated wandering, and the consolidation monitoring should be strengthened.
