Living with Avian influenza

An infection caused by bird flu viruses, which usually infect birds but rarely infect people.

Understanding Avian influenza

Avian influenza, also called bird flu, is an infection caused by flu viruses that normally infect birds but can rarely infect people.

The viruses usually infect birds such as chickens, other poultry, and wild ducks. Sometimes they infect other animals and, in rare cases, people. A few types have caused most infections in people: H5N1, H7N9, and H5N6. Infections in people have mainly been in Asia, Africa, Europe, the Pacific, and the Near East. There have been a few in the United States.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Fever
  • Cough
  • Sore throat (pharyngitis)
  • Headache
  • Muscle aches
  • Tiredness (fatigue)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
