No data are available on 2009 H1N1 influenza in human immunodeficiency virus (HIV)-infected children, a highly susceptible and vulnerable population. We report 13 cases of pandemic influenza among a cohort of HIV-infected pediatric patients. Clinical features of H1N1 influenza were similar to those described in the general population. Most patients received antivirals on an outpatient basis. An uneventful evolution was observed in all patients, only 2 of whom required hospitalization. Influenza had no effect on the evolution of HIV infection.
