Seasonal influenza and H1N1/09 Swine influenza have many of the same symptoms. H1N1 is very highly contagious and transmitted easily from person to person making the pandemic spread rapidly around the world in 2009. The symptoms have been similar for both in most people, although there is a subgroup of people who were at higher risk of complications and death from the Swine Flu.
