An influenza pandemic is an epidemic of an influenza virus that spreads on a worldwide scale and infects a large proportion of the world population. In contrast to the regular seasonal epidemics of influenza, these pandemics occur irregularly – there have been about 9 influenza pandemics during the last 300 years. Pandemics can cause high levels of mortality, with the 1918 Spanish flu pandemic being the worst in recorded history; this pandemic was estimated to be responsible for the deaths of approximately 50–100 million people. There have been about three influenza pandemics in each century for the last 300 years, the most recent one being the 2009 flu pandemic.
