title: [Investigation on current status of infections of soil-borne nematodes in Yunxiao County].
abstract: OBJECTIVE
  To understand the endemic situation of soil-borne nematodes and their distribution characteristics, so as to provide the evidence for formulating prevention strategy.
  
  
  METHODS
  According to The Survey Program of Important Human Parasitic Diseases in Fujian Province, the survey spots were determined by the stratified cluster randomly sampling method. The eggs of Ascaris lurmbricoides, hookworm and Trichuris trichiura in feces were detected by Kato-Katz technique; the eggs of Enterobius vermnicularis were checked by rectal swabs using transparent adhesive tape. A questionnaire survey was performed for recording the gender, age, education levels and related epidemiological factors.
  
  
  RESULTS
  Altogether 2002 residents in 21 villages of 4 towns were investigated. There were 169 residents infected with soil-borne nematodes (8.44%). The infection rates of hookworm, Trichuris trichiura and Ascaris lumbricoides were 4.35%, 1.70% and 0.15% respectively. The infection rate of Enterobius vermicularis was 13.48% (43/319) in children. The infection rates of soil-borne nematodes were higher in children aged below 7 years and residents aged above 45 years, and the infection rate was higher in the women than in the men. The infection rates 'vere negative correlated with the education levels.
  
  
  CONCLUSIONS
  The prevalence of soil-borne nematodes has a reduction trend in Yunxiao County. However, the infection rate of hookworm is still high in areas of mainly planting economic crops. The infection rate of Enterobius vermicularis is still high in children, and we should pay more attention to it.
