摘要: 全省按东、西、南、北、中方位,随机抽取5个县、市15个乡镇,用改良加藤法和试管滤纸培养法粪检7958人,查见钩虫感染者4846例,其感染率为60.9%。汉族、黎族、苗族和回族人群的钩虫感染率依次为47.8%、75.5%、87.3%和54.3%。钩虫感染率随着年龄增长而升高,但70岁以上年龄组的感染率有所下降。职业以农民的感染率79.8%为最高。农村钩虫感染率高于城镇、墟镇、海滩地带。4239例钩虫幼虫鉴定结果,单纯美洲钩虫感染者占75.1%,单纯十二指肠钩虫感染者占1.7%,两种钩虫混合感染者占23.2%,N.a.∶A.d.=4.37∶1。表明海南系以美洲钩虫为主的两种钩虫混合感染流行区。

Abstract: An investigation on hookworm infection was pursued by fecal examination. Fifteen townships in 5 counties (cities) were randomly sampled for the survey. A total of 4 846 out of 7 985 persons were found to infect with hookworm by Kato Katz method and test tube filter paper cultivation method. The overall infection rate was 60.9%, and the rates in Han, Li, Miao, and Hui nationalities were 47.8%, 75.5%, 87.3% and 54.3%, respectively. A trend of increase of incidence with age was indicated, except for age group above 70. The incidence in peasants was higher than in other occupations. Prevalence of the infection in rural area was higher than that in urban, township and coastal areas. 75.1% of the infected persons harbored simple Necator americanus and 1.7% simple Ancylostoma duodenale , as shown by hookworm larva cultivation. The mixed infection rate was 23.2% ( N.a.∶ A.d . = 4.37∶1). The result shows that Hainan Island is an endemic area of both species of hookworm with Necator americanus as the main species.
