河南省阻断班氏丝虫病传播的研究

STUDY ON ERADICATION OF FILARIASIS IN HENAN PROVINCE

１９８２－１９９５年，在河南省确山县赵庄等３个村班氏丝虫病中度流行区，采取普服０．３％－０．４％的海群生药盐４－６个月和微丝蚴血症者加服海群生４．２ｇ７日双疗程防治措施后，终止防治措施，进行病原学和蚊媒的纵向观察．结果表明，有效地控制微丝蚴血症者，使微丝蚴率降到１％左右、微丝蚴密度降到５条以下／６０μｌ，在１０年以内，可以阻断班氏丝虫病的传播，达到消灭班氏丝虫病的目的。

To control filariasis, mass tretment with 0. 3%-0. 4% diethylcarbamazine medicatedsalt for 4-6 months combined with double courses of 4. 2g/7-day diethylcarbamazine to microfilariemia cases were carried out in 3 villages of meso-endemic area of bancroftian filariasis of Queshan County, Henan Province during 1982-1995. After that, ecological and longitudinal surveillance were made. The results showed that since the micorfilaria rate reduced to about 1 % and the density of microfilaria dropped to< 5/60μl by effective treatment,the transmission of filariasis could be interrupted within 10 years.
