Avian flu

Avian influenza refers to the disease caused by infection with avian (birdinfluenza (flu) Type A viruses. These viruses occur naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species.

Symptoms begin within two to eight days and can seem like the common flu. Cough, fever, sore throat, muscle aches, headache and shortness of breath may occur.
The disease can carry a high mortality in humans. Some antiviral drugs, if taken within two days of symptoms, may help.
