Influenza viruses are divided into three main groups: influenza A, B and C. Type A viruses are the source of most seasonal flu epidemics and have caused all previous pandemics. Whereas influenza B and C viruses infect humans only, influenza A viruses also infects birds and other animals such pigs and horses. This ability to jump the species barrier enables influenza A viruses to cause pandemics.
