title: Pandemic influenza in Canadian children: a summary of hospitalized pediatric cases.
abstract: A total of 324 pandemic H1N1 cases were reported to the Immunization Monitoring Program, Active from May 1, 2009 to August 31, 2009. As of August 31, 2009, case details were available for 73% (n=235) of these cases. The median age was 4.8 years and 69% of children were older than 2 years of age. In total, 95 (40%) of children were previously healthy. The proportion with an underlying health condition increased with age. Close to 50% of children received antiviral medication. Two children died from the infection. The pediatric risk groups affected and course of disease caused by pandemic H1N1 appear similar to seasonal influenza.
