目的了解、掌握江苏省居民和家畜血吸虫感染情况,为制订防治规划提供科学依据。方法根据全国和江苏省血吸虫病疫情监测方案的要求,在全省血吸虫病流行区选择有代表性的82个流行村作为监测点,开展居民和家畜血吸虫感染情况的监测调查。结果全省监测点常住居民血检阳性率为1.63%、粪检阳性率为0.035%;流动人群血检阳性率为2.42%,粪检阳性率为0.988%。推算全省流行区居民平均血吸虫感染率为0.0074%,牛感染率为0.80%,羊感染率为1.90%。结论全省血吸虫病疫情继续呈较为稳定的低流行态势;流动人群血吸虫感染率远高于常住居民;全省流行区中散放的家畜较少,总体感染率较低,但局部地区家畜感染率仍较高。流动人群和家畜仍为全省局部地区重要的血吸虫病流行因素。
Objective To understand and master the situation of schistosomiasis infection among residents and livestock in Jiangsu Province and provide scientific basis for making prevention and control plan. Methods According to the requirements of the epidemic monitoring program of schistosomiasis in China and Jiangsu Province, 82 representative endemic villages were selected as the monitoring points in the endemic areas of schistosomiasis in the whole province to carry out the surveillance survey on the infection of schistosomiasis among residents and livestock. Results The positive rate of blood tests of resident residents at the monitoring sites in the whole province was 1.63% and the positive rate of stool tests was 0.035%. The positive rate of blood tests in floating population was 2.42% and the positive rate of stool tests was 0.988%. The average prevalence of schistosomiasis in the endemic areas of the province is estimated to be 0.0074%, bovine infection rate 0.80% and sheep infection rate 1.90%. Conclusions The epidemic situation of schistosomiasis in the whole province continued to be relatively stable and low-prevalence. The infection rate of schistosomiasis in floating population was much higher than that of resident population. Fewer livestock were released in endemic area of the province and the overall infection rate was lower. However, the infection rate of livestock in some areas Still high. Floating population and livestock are still the important epidemic factors of schistosomiasis in some areas of the province.
