Influenza pandemicis an epidemic influenza virus that infects a major portion of the population across the world, which occurs irregularly when compared to other seasonal epidemics. These viruses can be fatal as in the past Spanish influenza has killed over 50 million people. These pandemics were of three types in each century in the past 300 years. Recently it was 2009 flu pandemic.

The Influenza virusesat times are transmitted from wild birds that leads the outbreaks in domestic birds that in turn spreads to humans living close to those domesticated birds. It happens basically because of the migrating birds from one geographical place to another for seasonal changes. The commercial shipping of bird products can also cause it to happen.
