Totally 45 strains of non-polio enterovirus (NPEV) were isolated from acute flaccid paralysis (AFP) cases and their close contacts in Tianjin from 2001 to 2001. Among them, Coxsackie virus (Coxsackie, Cox. B) 15 strains, accounting for 33.3%; 13 strains of ECHO (accounting for 29.8%); In terms of time distribution, Cox.B virus mainly concentrated in June-August, accounting for 86.7%. ECHO viruses mainly concentrated in August-September, accounting for 92.3% of the total, indicating that NPEV mainly concentrated in summer and autumn. In terms of geographical distribution, 4 of 45 strains of NPEV were isolated from the urban area, accounting for 89%; 41 strains were isolated from suburban counties (91.1%), suggesting that the infection of enteroviruses was related to hygiene conditions.
