【摘要】 本文对比了华容县根据居民居住距江、湖易感地带的距离及流行程度所划分的层次,在采用常规治疗及扩大化疗9年中的晚期血吸虫病发病人数及发病率.发病人数之比是:Ⅰ层1:0.20,Ⅱ层1:0.41,Ⅲ层1:0.48,Ⅳ层1:0.65;晚期发病率在9年末期3年的下降幅度为:Ⅰ层70.00%,Ⅱ层37.50%,Ⅲ层54.76%,Ⅳ层46.81%.资料尚表明,晚血发病人数随着扩大化疗坚持年限的延长而逐渐减少;其发病率下降幅度与感染者能否得到及时化疗有关.更多还原

【Abstract】 This article contrasted the incidence of advanced schistosomiasis among local inhabitants and the rate of advanced schistosomiasis patients among the infected inhabitants under routine chemotherapy and extended chemotherapy at stratified areas in 9 years. The stratification was determined according to the distance from the resident sites to the sites of high transmission of schistosomiasis and the epidemic level of inhabitants in Huarong. The ratio of the incidence with these 2 therapeutic measures were as follows: Ⅰ (stratum) 1 : 0. 20, Ⅱ 1:0. 41, Ⅲ 1 : 0. 48, Ⅳ 1 : 0. 65. The reduction rate of average incidence rate of advanced schistosomiasis at the 7th 8th and 9th year among 9 years were: Ⅰ 70. 0% , Ⅱ 37. 50% ,Ⅲ 54. 76%, Ⅳ46.81%. It showed that the incidence of advanced disease would reduce gradually with lengthening of the period for extended chemotherapy,while the rate of reduction was ralated with chemotherapy of patients in time.更多还原
