摘要： 目的  掌握安徽省人体重要寄生虫病流行现状。 方法  按照全国统一调查方案，分层整群抽取48个农村调查点和18个城镇调查点，每个调查点调查人数不少于250人。改良加藤厚涂片法检查肠道蠕虫卵；试管滤纸培养法鉴定钩虫虫种；透明胶纸肛拭法检查12岁以下儿童蛲虫卵；直接涂片法检查肠道原虫包囊或滋养体。 结果  农村调查点共调查12 300人，城镇调查点共调查4 717人。检出肠道蠕虫10种，肠道原虫5种，蠕虫和原虫的感染率分别为1.95%和0.46%；钩虫和蓝氏贾第鞭毛虫感染者占蠕虫和原虫感染者的构成比分别为83.99%和63.16%。蠕虫感染者总体呈现女性高于男性，低学历人群高于高学历人群以及感染率随年龄增加而升高的特征；原虫的男女感染率差异无统计学意义，低学历人群感染率高于高学历人群，45以下人群感染率高于45岁以上人群。 结论  本次调查的人群蠕虫感染率比2002年下降90.90%，蠕虫以钩虫感染为主。原虫感染率总体较低，蓝氏贾第鞭毛虫是最常见的肠道原虫。家庭妇女和低学历人群为蠕虫和原虫的易感人群。

Abstract:

Objective  To understand the present epidemic status of human important parasitic diseases in Anhui province. Methods According to the unified methods formulated by the national investigation scheme and stratified cluster random sampling , 48 rural pilots and 18 urban pilots were selected in Anhui province. The number of the subjects investigated in individual pilot was defined over 250. Modified Kato-Katz thick smear was applied to detecting the eggs of intestinal helminthes. Tube fecal culture method was used to identify the species of hookworm．The Enterobius eggs were detected in children below 12 years old using adhesive-tape technique. The cyst and trophozoite of intestinal protozoa were examined by method of direct smear. Results A total of 12300 people in rural and 4717 people in urban areas underwent the survey. Ten species of worm and 5 species of protozoa were identified, with an average infection rate of 1.95% and 0.46%, respectively. The constituent ratio of hookworm in the people infected with worm was 83.99%, and this ratio of Giardia lamblia in protozoa was 63.16%. The infection rate of worm showed a rising trend from teenage-group to older-age group, and was higher in females and low-educated population. The rate of protozoa was higher in population aged below 45 years and also higher in the low-educated subjects, yet the difference was not significant between men and women. Conclusion The infection rate of protozoa appears in low level at present and Giardia lamblia is the most common prevalence. The worm infection rate dropped by 90.9% from 2002 to 2015, with hookworm being the most infection species. Housewives and low-educated people are in high risks for parasite infection.
