Flu (influenza) strain H1N1 spreading widely in Canada and USA

The flu (influenza) virus season that usually peaks in February and March is causing some concern in the USA and Canada. The major strain that is circulating is the H1N1 strain that was first identified in 2009. This strain is still circulating in Canada, USA and other countries. The reason for concern is that this strain is known to cause more illness in younger individuals, compared to older adults, and several deaths have been reported in previously healthy people between the ages of 20 and 60. The currently available flu vaccine includes the H1N1 strain and will provide protection.
