目的了解和分析海南省人体寄生虫感染的现状和流行特征,评估十多年来的防治效果,为制定全省人体重要寄生虫病防治策略提供科学依据。方法根据《全国人体重要寄生虫病现状调查实施细则》进行。结果整群随机抽样全省5个市、县15个点7924人,调查发现人群肠道蠕虫感染率为59·40%,其中土源性线虫感染率为56·22%,查见肠道蠕虫16种,其中线虫11种,绦虫2种,吸虫3种,感染率较高的虫种是钩虫、鞭虫和蛔虫,其感染率分别为33·18%、31·35%和14·29%;多虫感染较严重,感染度以轻度感染为主,感染年龄以5~9岁和10~14岁两组为高;汉、黎、苗、回各民族感染率分率别为48·27%、64·14%、76·36%、58·96%;女性和农村居民感染率明显高于男性和城镇居民。结论海南省人群土源性线虫感染率和感染度总体呈下降趋势,但儿童蛲虫感染率略有所上升,中部地区钩虫感染率仍然居高不下,是今后防治工作的重点。
Objective To understand and analyze the status quo and epidemic characteristics of human parasitic infections in Hainan Province and to evaluate the prevention and control effects over the past 10 years so as to provide a scientific basis for formulating prevention and treatment strategies for important parasitic diseases in the province. Methods According to the “National Survey of the implementation of the status of important parasitic diseases” carried out. Results A total of 7,924 people were randomly selected from 5 cities and counties in 15 counties in the whole province. The survey found that the prevalence of intestinal helminth infection in the population was 59.40%, and the infection rate of soil-borne nematodes was 56.22% 16 species, including 11 species of nematodes, 2 species of tapeworms and 3 species of trematodes. The higher infection rates were hookworm, whipworm and roundworm, with infection rates of 33.18%, 31.35% and 14.29% ; Multi-pest infection is more serious, the infection is mild infection, the infection age is 5 to 9 years old and 10 to 14 years old in both groups is high; Han, Li, Miao, Hui ethnic infection rate score 48 27%, 64.14%, 76.36%, 58.96%. The prevalence of infection among women and rural residents was significantly higher than that among men and urban residents. Conclusion The infection rate and infection degree of soil-borne nematodes in Hainan Province are generally on the decline. However, the prevalence of pinworm infection in children slightly increases and the infection rate of hookworms in the central area remains high, which is the focus of prevention and control work in the future.
