تعريف ومعنى "avian flu"

What is "avian flu"?

Avian flu, also known as bird flu, is a viral infection caused by influenza viruses that primarily affect birds. While most types of avian flu do not infect humans, some, such as H5N1 and H7N9, have caused occasional infections in people. Human cases of avian flu typically occur after close contact with infected birds or contaminated environments. Symptoms of avian flu in humans can vary but may include fever, cough, sore throat, difficulty breathing, and pneumonia. Severe cases can lead to complications and even death. Prevention measures include avoiding contact with sick birds, properly cooking their meat and eggs, and practicing good hygiene, such as handwashing.
