The results of enterovirus surveillance of acute flaccid paralysis (AFP) cases in Hebei province from 1997 to 1999 showed that 47 strains of poliovirus (poliovirus) were isolated and characterized by in-type characterization, respectively. Non-poliovirus 80 strains of enterovirus (NPEV) accounted for 63% of AFP cases. Among the specific types of strains, there are 1 type in Coxsackie (Cox) group A; 5 types in Cox B group are common in Cox B1; and those in Enterobacteriaceae (E CHO) 10 types, ECHO15 type in 3 years have separated. NPEV has significant summer and fall peaks, mainly occurring in the younger age group, with 77.5% of children under 5 years of age and 56.3% of those under 2 years of age.
