【摘要】 采用年传播潜势为指标,对确山县城郊公社三个大队的班氏丝虫病传播强度进行了观察。当地班氏丝虫病传播季节由6月下旬至10月上旬,约110天,以7月份传播强度为最高,每人可能被接种的感染期幼虫数为57条。三个大队的年传播潜势,在室外露宿者每人每个传播季节可能被接种的感染期幼虫数最高为95条,最低为12条,室内睡眠用蚊帐者最高为20条,最低为3条。更多还原

【Abstract】 Annual transmission potential was estimated as an indication for the intensity of bancroftian filariasis in Queshan County, Henan Province. The results were as follows.The mosquito biting rate was related to the mode and degree of exposure to mosquito at night. The average number of mosquito bites per person per night in Aug. -Sept. for those sleeping outdoors and those sleeping in the mosquito net indoors were 44 and 11 respectively, the former being similar to that for those sleeping indoors without mosquito net.The transmission season of bancroftian filariasis was estimated to be about 110 days. The intensity of transmission was highest in July, the number of infective larvae inoculated per person was 57.The annual transmission potential of filariasis in the three brigades investigated showed that among villagers sleeping outdoors the highest number of infective larvae inoculated per person per year or per transmission season was 95, while the lowest was 12; for those sleeping indoors with mosquito net, the highest was 20 and the lowest, 3.更多还原
