Abstract
This study aimed to determine the potential predisposing factors for the development of febrile seizures among children with upper respiratory tract infection in the eastern Chinese region. Participants were individuals aged 6 months and 6 years (n = 189) who were diagnosed with febrile seizure, complicated with upper respiratory tract infection, and 174 age-matched children who had upper respiratory tract infection without seizures as controls. The viral antigens including influenza A and B, parainfluenza, adenovirus, and respiratory syncytial virus were detected from nasopharyngeal aspirates. The incidence of influenza A infection was much higher in patients with febrile seizure than controls, especially those children aged >36 months. Patients with influenza A infection had higher body temperatures at seizure occurrence, shorter seizure duration, and shorter fever duration before seizure onset. Influenza A infections are frequently associated with febrile seizure in children with upper respiratory tract infection. During an influenza epidemic, effective vaccination of children, especially those with a past history of febrile seizure, may minimize the development of febrile seizure.
