摘　　要：目的研究广东省广州市肠道蠕虫的感染状况及流行特点,为防治蠕虫感染提供理论依据。方法根据广州市各区的地理分布,从1998—2010年的资料中分期分批选择不同职业不同年龄不同性别的人群作为研究对象,采用改良加藤氏厚涂片法粪检蠕虫卵。结果粪检共41 280人,阳性感染者6 211人,总肠道寄生虫感染率为15.0%,其中肝吸虫感染率为7.3%,钩虫感染率为3.3%,蛔虫感染率为3.4%,鞭虫感染率为1.1%。1998—2009广州市区肠道蠕虫感染率不断增高,2010年有所下降。职业中以工商人员的感染率最高,其次是农民、干部及医务人员;男性感染率明显高于女性。结论肝吸虫及农村土源性线虫仍是目前重点防治的寄生虫。应采取有效的综合防治措施,降低人群的肠道蠕虫感染率。Objective To study epidemic characterastics of helminth infection in Guangzhou and to provide basis for prevention and control of the disease. Methods Based on the geographic distribution,residents of different occupations,gender,and age groups were selected for the study from 1998 to 2010.Helminth ova in stool samples were detected by improved Kato＇s thick smear method. Results Totally 41 280 stool samples were tested and 6 211 positive infections were identified with an infection rate of 15.0%.The infection rate was 7.3% for clonorchis sinensis,3.3% for hookworm,3.4% for ascarid,and 1.1% for whipworm,respectively.The infection rate of intestinal helminth increased from 1998 to 2009,and decresed in 2010.Industrial workers and commercial staff had the highest infection rate,followed by farmers,govermment staff and doctors.The infection rate of the males was higher than that of females. Conclusion The Clonorchis sinensis and rural soil nematodes are still the major parasites for prevention and control.Effective measures should be taken to reduce the infection rate of intestinal helminth.
