title: [Surveillance of soil-transmitted nematodiasis in northern Jiangsu Province from 2006 to 2010].
abstract: OBJECTIVE
  To evaluate the control effect on soil-transmitted nematodiasis in surveillance sites of northern Jiangsu Province.
  
  
  METHODS
  According to "The Monitoring Program on Soil-transmitted Nematodiasis in Jiangsu Province", the eggs of soil-transmitted nematodes were detected by the Kato-Katz technique and cellophane anal swab technique, and the infection rates were predicted by the horizontal average speed development method in the surveillance sites from 2006 to 2010.
  
  
  RESULTS
  The overall infection rate of soil-transmitted nematodes declined to 3.13% and the intensities of the infections were mild in past 5 years in the northern Jiangsu Province, and the infection rates of Ascaris lumbricoides, hookworm, Trichuris trichiura and Enterobius vermicularis were 0.77%, 0.89%, 1.49 and 1.19%, respectively. The overall infection rates showed a downtrend. The predicted result also demonstrated that the future infection rates should keep a continuous downtrend, but the decreasing speed should be slower than before.
  
  
  CONCLUSIONS
  The infections of soil-transmitted nematodes in the northern Jiangsu Province have been controlled basically, and we should adjust the control strategy including surveillance and chemotherapy in the main risk population.
