title: [Evaluation on effectiveness of comprehensive control model for soil-transmitted nematodiasis].
abstract: OBJECTIVE
  To evaluate the effect of a comprehensive control model for soil-transmitted nematodiasis.
  
  
  METHODS
  Danling County was selected as a demonstration county carrying out the comprehensive prevention model centering on health education, nematode deworming, and drinking water and lavatories changing. On the other side, Hejiang was selected as a control. The effects were evaluated by comparing some indicators such as the infection rates of soil-transmitted nematodiasis and so on.
  
  
  RESULTS
  The infection rates of soil-transmitted nematodiasis declined obviously from 2006 to 2009 in the demonstration county. The infection rates of Ascaris lumbricoides, hookworms, Trichiuris trichiura decreased by 91.14%, 81.65% and 65.77%. In the control county, those rates did not have downward tendency. In 2006, those rates in the demonstration county were higher than those in the control, but in 2009 those rates in the demonstration county were lower than those in the control.
  
  
  CONCLUSIONS
  Through the three-year comprehensive prevention, the infection rates of soil-transmitted nematodiasis declined obviously in the demonstration county. The epidemic situation of soil-transmitted nematodiasis could be controlled effectively by the comprehensive prevention model.
