A severely immunocompromised child with uncomplicated oseltamivir-resistant 2009 H1N1 pandemic influenza infection

Abstract

2009 H1N1 pandemic influenza was associated with increased risk for severe disease in children and the immunosuppressed. We report a case of uncomplicated pneumonia because of infection with oseltamivir-resistant 2009 H1N1 virus in an immunosuppressed pediatric renal transplant patient. Innate immunity and/or altered viral fitness may be responsible for the mild clinical phenotype of the case.
