目的了解云南省祥云县人体重要寄生虫感染的现状和特点,为制定防治对策提供科学依据。方法按方位、地形或水系及经济发展水平等,将全县划分为5片区,每个片区随机整户抽取500人作为调查对象,采用kato-katz法检查寄生虫病。结果寄生虫总感染率为18.66%(469/2513),其中坝区与山区人群感染率分别为15.78%(161/1020)和20.63%(308/1493),两者差异有统计学意义(P<0.01)。共查出寄生虫6种,感染率分别为蛔虫18.15%、钩虫0.04%、鞭虫0.48%、其他(带绦虫、长膜壳绦虫、蛲虫)0.48%。混合感染占总感染人数的2.99%(14/469)。总感染率山区高于坝区,女性高于男性,1019岁年龄组居高,使用卫生厕所及有驱虫史者感染率较低。结论该地寄生虫总感染率低于2004年全省调查的28.86%和全国的19.56%。感染虫种以蛔虫为主,寄生虫病防治工作的重点是山区、女性及1019岁年龄段,加强健康教育、推广和使用无害化卫生厕所、定期群体性驱虫治疗是重点的防治手段。
Objective To understand the status quo and characteristics of important human parasitic infections in Xiangyun County, Yunnan Province, and to provide a scientific basis for making prevention and treatment measures. Methods According to the location, terrain or water system and the level of economic development, the county was divided into 5 districts, and 500 people from each area were randomly selected as the survey subjects. The kato-katz method was used to examine the parasitic diseases. Results The total infection rate of parasites was 18.66% (469/2513). The prevalence rates of infection in dam area and mountainous area were 15.78% (161/1020) and 20.63% (308/1493), respectively, with significant difference (P <0.01). A total of 6 parasites were detected. The infection rates were 18.15% for roundworms, 0.04% for hookworms, 0.48% for whipworms, and 0.48% for others (tapeworms, tapeworms, pinworms). Mixed infections accounted for 2.99% of the total number of infections (14/469). The prevalence of infection was higher in mountainous areas than in dam areas, with higher prevalence in women than in males and high in 1019 age groups. The prevalence of hygienic latrines and deworming infections was lower. Conclusion The total infection rate of parasites in this area is lower than 28.86% of the surveyed in 2004 and 19.56% of the national survey. Infectious worms are mainly roundworms. The focus of prevention and treatment of parasitic diseases is on mountainous areas, females and 1019-year-olds. Strengthening health education, promoting and using decontamination sanitary latrines, and regular group deworming treatment are the key prevention and control measures.
