To understand the status of human hookworm (Ancylostoma duodenale or Necator americanus) infection in Jiangxi Province.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.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).
