Acute flaccid paralysis is a complex clinical syndrome, with a wide variety of possible etiologies and with clinical manifestations that can vary according to age or geographical region. Enteroviruses (polioviruses and non-polio enteroviruses) are among the viral agents that can cause AFP. AFP surveillance is important for public health through its use in monitoring poliomyelitis, in the context of the Global Initiative to eradicate this disease. The current paper aims to assess the non-polio enteroviruses (NPEV) association with AFP and FP cases registered in Romania in the period 2001-2008 and to identify prevalent serotypes. Within the framework of Surveillance of AFP Cases Program, were collected samples from 579 children with AFP or FP (3.069 samples). The samples were processed and inoculated onto two types of cell culture (RD and L20B), according to WHO protocol. The identification of isolated viruses has been done by the reaction of seroneutralization with pools of specific antiserum and then with monospecific antiserum for confirmation. NPEV were isolated from 58 cases (123 positive samples). During the analyzed period, 23 NPEV serotypes have circulated (15 Echo serotypes and 8 coxsackie serotypes). The most frequently identified were the Echoviruses 13 and 11 and the coxsackie A viruses. 88% of positive cases have occurred in children between 1 and 5 years. As seasonal distribution, the peak of NPEV circulation was in the months August-September (36.2%). The paper provides information about NPEV circulation in Romania in the past 8 years, about its association with the AFP and FP and it indicates the need for monitoring NPEV circulation even after the eradication of poliomyelitis.
