摘要
目的了解云南省人体鞭虫感染现状,为制定云南鞭虫病防治策略措施提供科学依据。方法采用分层整群随机抽样方法,于2015年选取云南省10个调查县20个调查点进行调查。采集粪便标本,采用改良加藤厚涂片法,镜检记录感染虫种和感染者,统计人群感染率。应用SPSS 16.0软件进行统计学分析。结果共调查5067人,鞭虫感染数为429人,感染率为8.47%,轻、中和重度感染构成比分别为88.58%(380/429)、10.72%(46/429)和0.70%(3/429)。其中藏东-川西生态区鞭虫感染率为23.13%(294/1271),贡山县感染率为37.14%(283/762)。低年龄组感染率(15.68%,103/657)大于高年龄组,学龄前儿童(17.70%,77/435)和学生(10.68%,66/618)感染率高于其他职业人群。文盲组感染率(13.29%,179/1347)高于其他文化程度人群。独龙族感染率为68.66%(184/268)和傈僳族感染率为22.31%(58/260)大于其他民族。不同年龄组、职业、民族和文化程度间感染率差异有统计学意义(P<0.05)。结论云南省鞭虫感染率呈现区域化,部分少数民族地区感染率较高,应加强重点地区农民、学生和儿童等重点人群鞭虫病防治。
Objective To understand the human Trichuris trichiura(TTr)infection Yunnan Province,and we provide a scientific basis for the formulation of the strategy and measures for the prevention and control of Trichobiasis in Yunnan.Methods Total 20 survey sites were selected from 10 counties by using a satisfied sampling method.The modified Kato-Katz thick smear method were used for detection of TTr eggs,the results were observed through microcopy and infection rate was calculated.SPSS 16.0 software was used for statistical analysis.Results A total of 5067 people were investigated,429human TTr were detected,the infection rate of TTr was 8.47%.Among the TTr infections,most of them were mild infection(88.58%,380/429),with medium infection(10.72%,46/429)and severe infection(0.70%,3/429).The infection rate of the Eastern Tibet and Western Sichuan Eco-region was 23.13%(294/1271).The prevalence rate of TTr in Gongshan was 37.14%(283/762).Children with younger age had the highest prevalence of TTr infections(15.68%,103/657)than other age group.The prevalence of TTr with preschool education level(17.70%,77/435)and students(10.68%,66/618)was higher than other occupations.The infection rate of illiterate group(13.29%,179/1347)was higher than that of other literate groups.In terms of ethical nationality,Dulong people had the highest prevalence of TTr infections was 68.66%(184/268),the prevalence rate of Lisu people was 22.31%(58/260).There was significant differences in the prevalence of TTr infections among people with different age,occupations,education levels and ethical nationalities(P<0.05).Conclusion The survey results showed that the prevalence of Trichuris trichiura infections is still high in some minority areas and the infection rate of trichuriasis is regionalized in Yunnan Province.It is necessary to strengthen the prevention,control and surveillance measures for Trichuris trichiura in farmers,students and children who have the highest infection.
