In 1992, a screening of poliomyelitis caused lameness among children under 15 years of age was conducted to verify whether poliomyelitis has been absent in Anhui. A total number of 7 639 cases were diagnosed as poliomyelitis caused lameness. The prevalence rate was 0.44‰, the rate was higher in plains than in hilly and mountainous areas. Rate was higher in ural than in urban areas. The disease mainly occured in children at age below 3.
