Objective To study the surveillance result of Poliomyelitis pathology in Heibei province 1991 -2001 and provide scientific basis for realizing the goal of evanishing Poliomyelitis. Methods The epidemiological investigation to the AFP cases reported by the Hebei province AFP surveillance system was conducted according to WHO' s normal method and all the Poliovirus strains were sent to the national lab and detected by the PCR - RFLP.
