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.
