This bar chart displays influenza hospitalisations per 100,000 for age bands: 0-5 months, 6-23 months, 2-4 years, 5-11 years, 12-17 years, 18-24 years, 25-49 years, 50-64 years, 65-74 years, and 75 years or over separated into pre-pandemic (2006-2008), pandemic (2009), and post-pandemic (2010-2013) periods. There was a U shaped distribution with higher hospitalisation rates in the young and the elderly. For all time periods, the hospitalisation rate in age bands 0-5 months was highest followed by 6-23 months, and these were higher than all other age bands including the 75 years or over age band. During the 2009 pandemic, individuals 12-64 years of age had significantly higher hospitalisation rates than pre and post-pandemic periods.
