avian influenza的意思|示意

Avian influenza, also known as bird flu, is an infectious disease affecting both birds and humans, caused by certain kinds of influenza viruses. It is so named because it is usually found in birds, not humans. The avian influenza virus exists in two forms, H and N. H stands for \"host-specific\" and refers to how the virus is adapted to certain birds. N stands for \"non-host-specific\" and means that the virus can spread to different types of birds.

Avian influenza is spread by contact with infected birds or contact with their excreta, such as feces and nasal discharges. It is also spread from one bird to another through contaminated feed, water, and the air. Humans can get avian influenza by coming in contact with infected poultry or surfaces contaminated with the virus.

People infected with avian influenza most commonly have mild to moderate respiratory illness and may have a fever, sore throat, and other flu-like symptoms. In rare cases, avian influenza can cause severe disease and even death.

The most effective way to prevent avian influenza is to practice good hand hygiene, avoid contact with poultry or wild birds, cook poultry and eggs thoroughly, and cover the nose and mouth when in contact with infected poultry. Additionally, vaccines have been developed to reduce the risk of infection in poultry.
