Complex febrile seizures followed by complete recovery in an infant with high-titer 2009 pandemic influenza A (H1N1) virus infection.

We describe a 2009 H1N1 virus infection with a high viral load in a previously healthy infant who presented with complex febrile seizures and improved on oseltamivir without neurologic sequelae. Febrile seizures may be a complication in young children experiencing infection with high viral loads of 2009 H1N1 influenza virus.
