Super-acute avian influenza, also known as avian influenza, is a highly contagious avian viral disease that, if outbreak, not only causes extensive damage to the poultry industry but can be transmitted to humans.
Avian influenza or type A can usually not cause disease in humans and can only be transmitted to humans through infected birds and cannot be transmitted through infected humans.
With the announcement of the outbreak of bird flu in some provinces of the country, control and preventive measures were implemented by veterinary officials, and by observing and monitoring poultry farms and bird breeding centers that were illegally kept and infected with influenza, necessary measures were taken and measures were taken.

Super-acute avian influenza is a viral disease of birds; Influenza viruses are of three types: C, B, and A; In poultry, only type A can cause disease. In addition to poultry, this brigade affects other animals, including pigs, horses, and humans.

Wild and aquatic birds can carry bird flu viruses without becoming infected. Pigs act as intermediate hosts for avian and mammalian influenza viruses.
Wild waterfowl are considered to be the most important natural reserves of the flu virus, through which the virus is transmitted from one place to another and through saliva and feces, the disease is transmitted to domestic birds and those who come in contact with birds.
Humans can also get the disease in direct contact with sick birds or the carcasses of killed birds.
In the mild form of avian influenza, the disease is characterized by the loss of bird feathers and reduced egg production, and in the second type, the disease spreads rapidly among birds and causes large numbers of them to perish.
The disease is transmitted from one country to another through the trade of live birds and migratory birds such as ducks and other seabirds.

Chickens and roosters, turkeys, unicorns, ornamental birds, wild birds and ostriches are susceptible birds.
Coughs, sore throats, shortness of breath, and a history of contact in the week before the death of infected birds or in the infectious stage, and levels of virus and fever above 38 degrees are symptoms of avian influenza in humans.
In Iran, the source of this disease is migratory birds that enter warm or temperate regions from the cold northern regions in the cold season of the year.

Highly acute avian influenza is now prevalent in some countries, such as Japan and parts of Russia and Siberia, and Iranian wetlands are threatened by bird migration.
