目的调查对比分析 1 0年前 (1 991年 )后 (2 0 0 2年 )川西高原藏区常见肠道寄生虫病流行现状。方法采用经济及地形两特征分层整群随机抽样选点 ,用改良加藤氏法检查肠道蠕虫卵 ,对 1 2岁以下儿童用透明胶纸肛拭法检查蛲虫卵。结果该县肠道寄生虫总感染率 1 991年为 5 2 .7% (4 1 0 / 778) ,2 0 0 2年为 3 0 .3 % (1 5 1 / 4 98)。共查见肠道寄生虫 5种 ,1 991年及 2 0 0 2年感染率分别为 :蛔虫 40 .6% ,1 7.3 % ;鞭虫 3 .5 % ,5 .8% ;带绦虫1 3 .8% ,1 1 .2 % ;钩虫 0 .8% ,0 .4% ;蛲虫 1 1 .3 % ,0 %。结论该区 1 0年来总感染率呈下降趋势 ,钩、鞭、蛲虫感染率较轻 ,但 2 0 0 2年学龄儿童 3 0 %左右的蛔虫感染率及农牧民 1 8.
Objective To assess the current situation of intestinal parasitoses in Tibetan area of western plateau region of Sichuan based on investigations made in Dege County during 1991 and 2002. Methods Three spots were selected by double charateristics stratified cluster sampling. The parasites eggs were examined by modified Kato Katz thick smear technic and Enterobius vermicularis eggs by cellophane anal swab. Results Five kinds of parasites eggs were detected out with total infection rates of 52.7%(410/778) in 1991 and 30.3%(151/498) in 2002. In 1991 and 2002, the infection rates of ascariasis were 40.6%, 17.3%; trichuriasis 3.5%, 5.8%; taeniasis 13.8%,11.2%; hookworm disease 0.8%,0.4%; enterobiasis 11.3%, 0% respectively. Conclusion Because of about 30% infection rate of ascariasis among children and about 18.9% infection rate of taeniasis among herdsmen and farmers, the intestinal parasitoses in such area has caused severe public health problem though the infection rates of hookworm disease, trichuriasis and enterobiasis were slight and the intestinal parasitoses situation revealed declining tendency.
