Although we are now in the post pandemic phase, the A H1N1 virus has now emerged as the predominant strain of virus in the seasonal influenza season that is currently affecting the northern hemisphere. Current experience in the United Kingdom shows that the population below the age of 65 years are worst affected by the complications of the flu and that the deaths associated with the flu are predominantly associated with the H1N1 virus. From October 2010 to early January 2011, 50 deaths were reported by the Health Protection Agency. Forty-five of these people died with the H1N1 (2009) strain and 5 with Influenza B. The majority were under 65 years of age and five were under the age of five [4] .
