Avian influenza, avian flu or bird flu, is an infectious disease that affects birds, wild fowl and poultry.

Avian influenza is a virus that can infect both birds and humans.

It is typically spread through contact with infected birds, but can also be spread through contact with contaminated surfaces.

Symptoms of avian influenza in humans include fever, cough, sore throat, headache, runny nose and fatigue.

Birds can get infected with avian flu through contact with other infected birds, or through contact with contaminated surfaces.

The virus can also be spread through the air, particularly in enclosed spaces.

The dangers of avian flu are numerous and should not be taken lightly.

This virus has the potential to cause serious respiratory illness in humans and can even be deadly.

There is no vaccine for it, so avoiding contact with birds is a good idea.

Treatment for avian influenza may include medications such as Tamiflu or Relenza and supportive care including fluids and rest.
