According to the latest Health Protection Agency figures across the UK, 440 fatal pandemic influenza cases were identified between 27 April 2009 and 12 March 2010. However, most of these cases had underlying risk factors for severe illness anyway.
Unlike seasonal influenza, where deaths occur mainly amongst the elderly, the majority of the pandemic influenza deaths observed during the height of the 2009/2010 pandemic in the UK were amongst the young and middle-aged adults. Although the overall case fatality rate (CFR) was low for pandemic influenza A(H1N1) 2009, it was particularly higher amongst those with underlying chronic neurological disease, chronic respiratory disease, chronic liver disease and immunosuppression. Pandemic influenza infection during pregnancy was also a risk factor for death.
