通过对江滩地区的一个血吸虫病流行村连续４年的观察，发现在实施高危人畜化疗结合易感地带灭螺措施后，居民的血吸虫病感染率从３．４５％降至０．０６％．下降了９８．３％，且连续４年未发生血吸虫病急性感染；江滩感染性钉螺面积和感染性钉螺密度分别下降了７２．５％和４１．１％。提示：在江滩地区，该防治措施能有效地控制血吸虫病的流行．降低江滩的危险性。 After a continuous 4-year observation of a schistosomiasis endemic village in the Jiangtan area, it was found that the infection rate of schistosomiasis among residents decreased from 3.45% to 0.06% after the implementation of high-risk human-animal chemotherapy combined with snail-killing measures in susceptible areas. Decreased by 98.3%, and no acute schistosomiasis infection occurred for 4 consecutive years. Infectious snail area and infected snail density decreased by 72.5% and 41.1%, respectively. Tip: In the river beach area, the control measures can effectively control the prevalence of schistosomiasis. Reduce the danger of riverbanks.
