Avian influenza is an infectious disease caused by influenza A viruses that occur in poultry and wild birds. The virulence of different subtypes of avian influenza viruses varies greatly, and the virulence of different strains of the same subtype and the same strain infects different poultry. Non-pathogenic and low-pathogenic strains tend to cause only mild respiratory symptoms.
However, the rapid spread of highly pathogenic avian influenza, the short duration of the disease, and the high mortality rate (75% to 100%) cause huge economic losses.
The disease can be transmitted by a variety of diseases, including blood-sucking insects. In nature, the virus present in nasal secretions and feces, due to the protection of organic matter, has great protective power, and can still be isolated from wet manure after 105 days after the elimination of sick chickens, the virus can survive for 18 days in feathers, 18 months in frozen poultry meat and bone marrow, and often can be isolated from lakes and ponds where poultry have influenza virus. The virus has been isolated from guinea fowl, geese, pheasants, starlings, gulls, seabirds, etc., and cats, ferrets, monkeys, and humans can be infected with influenza viruses from poultry in artificial inoculation experiments.
Therefore, it is of great significance to prevent the outbreak of this disease.
