摘要
目的了解云南省城镇地区人群肠道蠕虫感染现状,为防治策略的制定提供依据。方法2015年按照《全国人体重点寄生虫病现状调查方案》和实施细则要求,采用整群随机抽样的方法从云南省抽取5个县(区)共7个调查点,采集1岁以上本地常住居民粪便,每个调查点不少于250人,采用改良加藤厚涂片法镜检虫卵(一粪二检)。结果共粪检1757人份,蠕虫感染33例,感染率为1.88%。共检出蛔虫、鞭虫、钩虫3种肠道蠕虫,均属土源性线虫,感染率分别为1.08%(19/1757),0.34%(6/1757)和0.4%(7/1757),其中蛔虫和鞭虫混合感染1例。感染度以轻度为主(31例),中度感染2例(蛔虫和混合感染)。5个县(区)人群肠道蠕虫感染率以古城区较高,为4.35%(11/253),麒麟区未检出感染者,各县之间感染率差异有统计学意义(χ^(2)=11.20,P<0.05)。女性肠道蠕虫感染率2.74%(25/911)与男性感染率0.95%(8/846)比较差异有统计学意义(χ^(2)=7.63,P<0.01)。60~岁组肠道蠕虫感染率较高,为3.31%(6/192),不同年龄组人群感染率差异无统计学意义(χ^(2)=4.66,P>0.05)。纳西族感染率较高,为15%(3/20),白族3.98%(7/176)。小学文化程度人群感染率较高,为2.97%(15/506),高中、中专及以上人群未发现肠道蠕虫感染者。家庭妇女感染率较高,为7.36%(9/122)。不同民族、文化程度及职业人群之间感染率差异均有统计学意义(P<0.01)。结论云南省城镇地区人群肠道蠕虫感染水平整体偏低,今后仍应加强重点人群的防控。
Objective To ascertain and analyze the status of infection with intestinal helminths in Yunnan Province.Methods A cross-sectional survey was conducted in accordance with the National Program to Examine the Current State of Key Parasitic Diseases in Humans in 2015.Seven sites in 5 counties(districts)were selected using random cluster sampling,and stool samples collected from at least 250 permanent residents over the age of 1 were microscopically examined using the Kato-Katz technique in duplicate at each site.Results Samples were obtained from a total of 1757 participants,and 33 were infected with an intestinal helminth,with an overall prevalence of 1.88%.Three types of intestinal helminths were found,all of which were soil-transmitted nematodes.The prevalence of Ascaris lumbricoides was 1.08%(19/1,757),that of Trichuris trichiura was 0.34%(6/1757),and that of a hookworm infection was 0.4%(7/1757).There was 1 case of a mixed infection(A.lumbricoides and T.trichiura).There were 31 cases of a mild infection and 2 cases of a moderate infection(A.lumbricoides and a mixed infection).The rate of infection differed among 5 different counties(districts),and the rate of infection was highest in the Gucheng District(4.35%,11/253).There were no cases of infection in the Kirin District.The rate of infection differed significantly in different counties(χ^(2)=11.20,P<0.05).The rate of infection in females(2.74%,25/911)was significantly higher than that in males(0.95%,8/846)(χ^(2)=7.63,P<0.01).A higher rate of infection(3.31%,6/192)was noted in individuals over the age of 60.The rate of infection did not differ significantly among different age groups(χ^(2)=4.66,P>0.05).A higher rate of infection(15%,3/20)was noted in the Naxi ethnic group,followed by the Bai ethnic group(3.98%,7/176).A higher rate of infection(2.97%,15/506)was noted in individuals with only a primary school education,and none of the individuals with a middle or high school education were infected.In terms of occupation,housewives had a higher rate of infecti
