Avian influenza is caused by influenza a virus of avian infectious disease, a common can be divided into low pathogenic avian influenza (low pathogenic avian influen - za, LPAI) and highly pathogenic avian influenza (highly pathogenic avian state-run, HPAI). Due to low pathogenic avian influenza virus pathogens spread from poultry and other reservoir to susceptibility to chickens, ducks and other poultry, after several times of circulation infection, may occur a series of mutation into a highly pathogenic avian influenza virus, which has serious deadly. Therefore, the development of a series of disease caused by avian influenza virus, the symptoms and prevention, treatment measures has become the current of nots allow to ignore a problem to be solved.
