【摘要】 本文以安徽省人体寄生虫分布调查的资料为基础,分析两种人体钩虫在我省分布,流行的特点。明确了我省是以十二指肠钩虫为主两种钩虫混合感染的流行区,全省钩虫的平均感染率为33.44%,性别分布男女间感染无显著差异,但在年龄分布上随年龄增大感染率上升,且成年组感染率(37.75%)显著高于少年组(22.68%),P<0.01,显示生产劳动与钩虫感染有着密切的联系。钩虫的地区分布特点,平原丘陵地区十二指肠钩虫感染率以及钩虫的总感染率高于山区,似与平原和山区的生产方式及农作物不同有关。我省钩虫感染在家庭内呈聚集性分布。此次调查所获结果为今后制定我省钩虫病防治措施提供了科学依据。更多还原

【Abstract】 This paper,based on the survey of human parasite infection in Anhui province,analyzed the distribution and epidemic characteristics of two species of hookworms.The result showed that the mean infection rate was 33.44%,with no significant difference between male and female.But a trend of increase of incidence with the growth of age was indicated.The infection rate in people ahove 15 years old (37.75%) was higher than that under 14 years old (22.68%) (P<0.01),which was attributed to the frequency of farming work.The overall infection rate of two species,as well as that of A.duodenale,was higher in plain and hilly regions, compared with mountainous regions,reflecting the different crops and ways of production in these areas.It also demonstrated that mixed infection of two species of hookworm existed and A.duodenale was the predominant species in Anhui province.Their distribution showed family clustering.更多还原
