Pandemic (H1N1) 2009-associated pneumonia in children, Japan

Abstract

To describe clinical aspects of pandemic (H1N1) 2009 virus-associated pneumonia in children, we studied 80 such children, including 17 (21%) with complications, who were admitted to 5 hospitals in Japan during August-November 2009 after a mean of 2.9 symptomatic days. All enrolled patients recovered (median hospitalization 6 days). Timely access to hospitals may have contributed to favorable outcomes.
