N2 - Reverse-transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) has become the gold standard for the diagnosis of human enterovirus (EV) and parechovirus (HPeV) infections. The detection rate of RT-qPCR in different pediatric body specimens has not been compared prospectively in a multicentre study. This study compared the diagnostic detection rates of EV and HPeV RT-qPCR and viral culture in different specimens (feces, nasopharynx, blood, urine and cerebrospinal fluid (CSF)) of pediatric patients. This prospective, multicenter study performed an EV and HPeV RT-qPCR on nasopharynx, blood, urine, feces and CSF specimens and a viral culture on nasopharynx, feces and CSF specimens in symptomatic children <16 years. Of 285 included children EV was detected in 140 (49%) and HPeV in 44 (15%) children. Both EV and HPeV RT-qPCR had a higher sensitivity and negative predictive value than EV and HPeV viral culture, respectively. EV and HPeV RT-qPCR in feces specimen had the highest sensitivity (99.2% and 95.1%) of all specimens. Pooling results of specimens increased the detection rate for both viruses. Of all specimens, RT-qPCR in feces had the highest detection rate for both EV and HPeV in symptomatic pediatric patients. An EV was detected in all EV positive patients if a RT-qPCR was performed on both feces and CSF specimens or in both feces and urine specimens. HPeV was detected in all HPeV positive patients if a RT-qPCR was performed on both feces and CSF specimens, feces and nasopharynx specimens or CSF and nasopharynx specimens
