Pandemics are caused by influenza viruses that occur naturally in birds or swine. There are differences among the viruses, but the one thing all viruses have in common is that they constantly change. Three subtypes of flu virus are currently common in people (H1N1, H1N2, and H3N2). When a virus changes into a subtype that humans are not use to, a pandemic may occur.
