Health officials have announced an early start to this year's flu season in Canada, with over 2,102 influenza detections since late August, significantly higher than previous years. The majority of cases (98%) are caused by the H1N1 strain, which tends to be less severe but can still cause widespread outbreaks. In Alberta, more than 400 confirmed flu cases have been reported ahead of vaccine availability, with one fatality in a person aged 70-79. Despite early concerns, some experts like Brian Ward from McGill University suggest that this does not necessarily signal a harsher season overall, as other regions remain quiet.
