摘要 人体肠道寄生虫在上海市浦东新区是一个重要的公共卫生问题。5个调查点一次粪检共查2714人,总感染率为56.2%,共检出7种寄生虫。蛔虫、鞭虫、蛲虫在所有的调查点均有流行;钩虫和结肠内阿米巴在大部分地区为轻度流行。 鞭虫的感染率为14.2-69.4%,4/5的调查点属中、重度流行区;蛔虫的感染率为7.3-60.8%,前者的感染率显著高于后者,其原因有待进一步研究。根据虫卵计数,大部分蛔虫、鞭虫感染属轻度。乡村居民肠道寄生虫感染远高于城镇,性别间无显著差异。按年龄分析表明蛔虫和鞭虫感染率均以10—14岁年龄组为最高,60岁以上年龄组呈下降趋势。 A survey on the present status of intestinal parasite infections was carried out in 6 selected spots in Pudong New Area, the suburbs of Shanghai in 1988-Of 2714 individuals examined, 1624 (66.2%) were proved to be infected with intestinal parasites. Multiple infections were common (18.9%). A total of 7 species of parasites were identified including 2 protozoa and 5 helminths. The infection rates of Ascaris lumbricoides, Trichuris trichiura, and Enterobius vermicularis were 25.9%, 44.6% and 23.7%, respectively. Low prevalence of hookworm (0.7%), Entamaeba coli (0.4%), Giardia lamblia (0.04%) and Hymenolepis diminuta (0.04%) were also noted in these areas.Being the predominant parasite, the prevalence of T. trichura varied from 14.2-69.4%, which was followed by Ascaris infection (7.3-60.8%). Most cases contracted light infection based on fecal egg count (EPG: Ascarias<5000: Trichuris<1000).The overall rate of intestinal parasite infection in inhabitants of Gao-qiao Town (24.2%) was found lower than that of the other 4 villages (45.4-82.0%). The rate for females (68.0%) was much higher than for males (63.3%). The highest infection rate of Ascaris and Trichuris was in the age group of 10-14 years, and a decrease tendency was revealed in those above 60 years old.
