A GREAT SUCCESS IN LYMPHATIC FILARIASIS CONTROL IN CHINA

中国的淋巴丝虫病防治于１９５６年列入国家规划。１９５６－１９９４年，全国共血检普查丝虫病７０７４２１７３６人次，查出微丝蚴血症２３４２８４８０人次；海群生化疗２６００４１６４５人次，其中治疗微丝蚴血症３３８８８９９７人次，全民服药３１６１８１４４人次，食用药盐１８３７０１６５８人次。迄１９９４年，全国１５个省、自治区、直辖市共８６４个流行县、市通过考核均已达到基本消灭丝虫病标准（以行政村为单位，经防治使微丝蚴率降至１％以下）。已达基本消灭丝虫病地区，正开展丝虫病系统监测。按各省、自治区、直辖市达基本消灭丝虫病标准第２年起的监测资料，１９８４－１９９３年，累计血检调查８０８５５０８人次，查出微丝蚴血症３２１４人次，各地病原学监测的微丝蚴率、蚊媒监测的幼丝虫自然感染率及血清学监测的ＩＦＡ和ＥＬＩＳＡ抗体阳性率均呈逐年下降趋势。初步监测结果显示，在基本消灭丝虫病后的大多数原流行区淋巴丝虫病的传播已被阻断，但仍存在少数防治过程中的薄弱环节地区。按病原学和临床学监测资料，估计目前全国尚有微丝蚴血症者１０５７３２人和有丝虫病临床表现者１３９６６６５人。

A GREAT SUCCESS IN LYMPHATIC FILARIASIS CONTROL IN CHINA

Lymphatic filariasis control was first included in national program in 1956.Since then,a large scale anti filariasis campaign has been carried out extensively throughout the endemic areas.From 1956-1994,a cumulative total of 707 421 736 person time were comprised in nationwide blood examination,and a total of 260 041 645 person time DEC chemotherapy were conducted(including selective treatment,mass chemotherapy and DEC fortified salt).Up to 1994,all of the 864 endemic counties/cities in 15 provinces/autonomous regions/municipalities had achieved effective control of filariasis successively.Parasitological,entomological and serological surveillance during the past few years demonstrated that the transmission of both bancroftian and malayan filariasis have been virtually interrupted in most of the areas reaching the criterion for effective control of filariasis.
