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 the infectious status and epidemic characteristics of intestinal worms in Guangzhou, Guangdong Province, and provide a theoretical basis for the prevention and treatment of helminth infections. Methods According to the geographical distribution in different districts of Guangzhou, from 1998 to 2010, the data of different occupations of different ages and different genders were selected in batches as the research object, and the worm eggs were stung by the modified Kato’s thick smear method. Results A total of 41 280 people were tested for faeces, 6 211 were positive, and the total infection rate of intestinal parasites was 15.0%. The infection rate of hepatic flukes was 7.3%, the infection rate of hookworm was 3.3% and the infection rate of roundworm was 3.4% The worm infection rate was 1.1%. In 1998-2009, the prevalence of intestinal helminth infection in Guangzhou increased continuously, dropping in 2010. Occupation in the highest rate of business people infected, followed by farmers, cadres and medical staff; male infection was significantly higher than women. Conclusion Liver flukes and soil-borne nematodes in rural areas is still the focus of prevention and control of parasites. Effective prevention and treatment measures should be taken to reduce the intestinal infection rate of the population.
