Febrile seizure (FS) is the most frequent juvenile neurological condition, and it is a significant health issue with possible short- and long-term repercussions, as well as an economic burden and heightened parental concern about fevers and seizures in their children. Although there are no standard recommendations for detecting the etiological reasons of FS from a neurological standpoint, more understanding regarding the etiological causes of FS in children will promote preventative interventions and follow-up methods. The purpose of this study is to determine the prevalence of respiratory viruses in children with FS. At the presentation, all children had nasopharyngeal swabs collected. A respiratory multiplex array was used to look for influenza A and B, respiratory syncytial virus A and B, human parainfluenza viruses 1-2-3 and 4, human coronavirus 229E and OC43, human rhinovirus, human enterovirus, human adenovirus, human bocavirus, and human metapneumovirus. During the research period, at least one virus was found in 82.7% of FS children. Adenovirus was the most often found virus, followed by influenza A and influenza B. The presence of more than one virus was detected in 58.3% of the children with FS, with adenovirus and influenza B being the most prevalent co-existence. Coronavirus OC43 was the most common in children under the age of 12 months, whereas influenza A was the most common in children above the age of 48 months (p < 0.05). Human bocavirus was more frequent in children with complicated FS, but respiratory syncytial virus (RSV) A was more common in children with simple FS. The influenza B virus was the most commonly detected virus in youngsters suffering their first episode of FS (p < 0.05).
