Abstract: 6 257 children in 39 kindergartens were examined by adhesive tape wiping in the morning during April，2009 to November，2010， and 460 children were found pinworm infected with a prevalence of 7.4%（460/6 257）， 7.7%（260/3 359）in girls and 6.9%（200/2 898）in boys. Children in junior class had lowest infection rate of 4.6%（77/1 667），while children in senior class had highest rate of 9.7%（252/2 594）（χ2=36.8，P<0.01）. Furthermore, the rate in public kindergartens（6.5%，255/3 927） was lower than that in private kindergartens（8.8%，255/2 330）（χ2=11.4，P＜0.01）, and the rate in urban kindergartens（12.4%，199/1 611）was much higher than that in rural kindergartens（5.6%，261/4 646）（χ2=79.7，P＜0.01）. Evidently，pinworm prevalence is high in children in Ninghai, and it is higher in private and urban kindergartens than in public and rural ones respectively.
