Explanation:
Influenza virus is capable of the genetic reassortment. This reassortment involves the reassortment of genetic parts in between two influenza strain. This takes place due to the ability of influenza virus to alter or modify the structure of Hemagglutinin (HA) and neuraminidase.
Some other characters also helps them to develop different strains for different host such as mutation, antigenic drift and many other conditions. Influenza virus subtype A are belongs to the avian host so they affect the birds such as duck, swan, gesse. Other than avian variants there is another strain that affect pigs known as swan variants. These strains are virulent if reassorted with human strains.
