Abstract: Objective To understand the status of human hookworm （Ancylostoma duodenale or Necator americanus） infection in Jiangxi Province. Methods A stratified cluster random sampling was conducted based on the geographical location and economic condition in 2014. Kato?Katz??s thick smear method was used for stool examinations， and filter paper cultivation was conducted for distinguishing the species of hookworms. Results A total of 21 615 persons were involved in the investigation， and there were 1 095 persons infected with hookworm with the prevalence of 5.07% （standardized rate of 4.05%）. The infection rate of hookworm in Nanfeng County was the highest （13.96%）. Most of the infected people had low worm burden （95.43%）. The infection rate of hookworm of the female was higher than that of the male （[χ2] = 28.03， P < 0.05）. The prevalence increased with the age， while the infection rate of hookworm in people at ages of 75 years and higher was the highest （14.79%）. Housewife was the highest risk occupation with the infection rate of 7.55%. The differences of infection rates among different educational level groups were significant （[χ2] = 135.88， P < 0.05）. The prevalence rates of hookworm in different landforms were significantly different （[χ2] = 34.37， P < 0.05）. The priority species was N. americanus（80.41%）in Jiangxi Province. Conclusions The infection rate of hookworm decreases obviously in Jiangxi Province. The high risk groups of hookworm infection are the people with low educational level， female and elder age?group.

摘要： 目的 了解江西省钩虫病流行状况。方法 2014年按生态区和经济水平在江西省进行分层整群随机抽样，对调查对象采用改良加藤厚涂片法进行钩虫感染病原学检查，应用试管滤纸培养法区别十二指肠钩虫和美洲钩虫。结果 全省共调查21 615人，钩虫感染1 095人，感染率为5.07%，标化感染率为4.05%。不同县（市、区）钩虫感染率以南丰县最高（13.96%），感染者以轻度感染为主（95.43%），女性钩虫感染率高于男性（[χ2] = 28.03，P < 0.05）。感染率随年龄增长呈上升趋势，75～岁年龄组钩虫感染率最高（14.79%）。家庭妇女为钩虫感染率最高的职业（7.55%）。不同文化程度者钩虫感染率差异有统计学意义（[χ2] = 135.88，P < 0.05），不同地形村居民钩虫感染率差异有统计学意义（[χ2] = 34.37，P < 0.05）。虫种以美洲钩虫为主（80.41%）。结论 江西省钩虫感染率下降趋势明显。文化程度低、女性、高年龄组为感染高危人群。
