Reported Influenza Hospitalizations and Deaths in Canada: 2009-10 to 2014-15 (data to February 21, 2015)
Note: Flu seasons run from week 35 (August) to week 34 (August)
In Canada the influenza season generally picks up from November of one year and slows down March of the following year. Hospitalizations and deaths with influenza are a measure of severity in the influenza season. On a weekly basis throughout the flu season, a subset of provincial and territorial Ministries of Health report the number of hospitalized cases and deaths with influenza to the Public Health Agency of Canada.

Hospitalizations with influenza
The first figure (Figure 1) shows the reported number of hospitalizations with influenza over the past six influenza seasons, from the 2009/2010 season up to February 21, 2015 of the 2014/2015 season. This shows that during the pandemic year, the total number of hospitalizations exceeded those in any of the subsequent influenza seasons. The two seasons following the pandemic were relatively mild, followed by the 2012/2013 and 2013/2014 seasons, when a considerable number of adult hospitalizations were reported. Over the last four influenza seasons, the number of paediatric hospitalizations reported has been relatively stable.
To date, 5204 hospitalizations have been reported from participating provinces and territories for the 2014/2015 influenza season.

* It is important to note that the number of hospitalizations and deaths reported represent a subset of all influenza-associated hospitalizations and deaths in Canada as not all Provinces and Territories participate in reporting. Number of participating Provinces and Territories: 2009-10: 13, 2010-11: 10, 2011-12: 10, 2012-13: 8, 2013-14: 9, 2014-15:9

Deaths with influenza
The second figure (Figure 2) shows the reported number of deaths with influenza over the past six influenza seasons, from the 2009/2010 pandemic season up to February 21, 2015 of the 2014/2015 season. In the past five influenza seasons, the number of deaths with influenza has followed a similar pattern to the reported hospitalizations (Figure 1). The number of deaths among children has been relatively consistent since the 2009/2010 season, while the number of adult deaths was higher during the pandemic season and during the 2012/2013 and 2013/2014 seasons. To date, 364 deaths have been reported from participating provinces and territories for the 2014/2015 influenza season.
