Population and methods. -Multicenter prospect ive study in 2 pediatric university hospitals, in Marseille, France. Nasal swabs for flu A were performed in all the febrile children admitted during winter 200 3-2004. Pre and postoutbreak admissions in pediatric and pediatric emergencies departments were compared too. Results. -During the outbreak, 941 children were admitted and 605 were tested for flu A. Nasal swabs were positive in 111. Attac k’s rate was 11.8%. In these children, infants under 2 years were 66%. Respir atory forms were uncommon, although febrile seizures and digestive troubles were much frequent. The mean hospitalization duration was almost 4 days. Flu A outbr eak finally increased the pediatric and pediatric emergencies departments rates of admission, of 48%and 37%respectively.
