【摘要】 目的　掌握湖北省血吸虫病流行现状和特点 ,为制订防治规划提供科学依据。方法　采用分层整群随机抽样方法 ,抽取全省 5 1个县 (市 ) 71个流行村 ,进行人群粪检查病。其中传播未控地区样本村 3 9个 ,传播控制地区 11个村 ,传播阻断地区 2 1个村。结果　抽取样本村和人群比例为全省疫区村的 1.2 %和 1.2 8%。人群查病受检率占应检对象 95 %以上 ,体检实检率超过 3 0 %。全省平均人群粪检阳性率和人群感染度 (EPG)分别为 4.18%、1.44。分层人群粪检阳性率和感染度 ,未控制地区居民分别为 4.77%、1.65 ,其中湖沼垸内亚型为 4.99%、1.86,湖沼洲滩亚型为 3 .97%、0 .82 ,山丘丘陵亚型为 2 .72 %、0 .19。传播控制和传播阻断地区粪检阳性率、感染度分别为 0 .2 6%、0 .11和0 .3 2 %、0 .1。体检各项指标均相应好转。晚期血吸虫病患病率为 0 .40 %。结论　与 1995年全省抽样调查相比 ,流行区居民感染率下降 41.86% ,其中未控制地区居民感染率下降 45 .88% ,传播控制地区下降 2 6.5 3 % ,传播阻断地区下降 3 2 .65 %。推算全省病人数下降 14 .97% ,病牛数下降65 .66%。更多还原

【Abstract】 Objective To understand the epidemiological situation of schistosomiasis and provide the scientific basis for making the control program in Hubei Province. Methods The stratifying and clustering random sampling technique was applied in this survey. The 71 villages were sampled including 39 uncontrolled villages of schistosomiasis, 11 controlled villages and 21 transmission interrupted villages. Results The sampling ratios of villages and population were 1 22% and 1 28% of the whole endemic villages in Hubei Province, respectively. The cover rate of stool examination was over 95% and physical examination over 30%. The positive rate of stool examination was 4 18% and EPG was 1 44 in whole province. The positive rate of stool examination and EPG were 4 77% and 1 65 in endemic areas including subtype of inner embankment 4 99% and 1 86, subtype of islet 3 97% and 0 82, subtype of hill 2 72% and 0 19. The positive rate of stool examination and EPG were 0 26% and 0 11 in controlled areas, 0 32% and 0 1 in transmission interrupted areas. The indexes of symptom survey were improved. The morbidity of advanced shisotosomiasis was 0 40%. Conclusion Comparison with the survey in 1995, the infection rate of schistosome in endemic areas declined by 41 86%, among them, 45 88% in uncontrolled area, 26 53% in controlled areas and 32 65% in transmission interrupted areas. According to this survey, the patients declined by 14 97% in whole province, and infected cattle declined by 65 66%.更多还原
