Diseases and Conditions

Bird flu (avian influenza)

Symptoms

Signs and symptoms of bird flu may begin within two to seven days of infection, depending on the type. In most cases, they resemble those of conventional influenza, including:

  • Cough
  • Fever
  • Sore throat
  • Muscle aches
  • Headache
  • Shortness of breath

Some people also experience nausea, vomiting or diarrhea. And in a few cases, a mild eye infection (conjunctivitis) is the only indication of the disease.

When to see a doctor

See your doctor immediately if you develop a fever, cough and body aches and have recently traveled to a part of the world where bird flu occurs. Be sure to let your doctor know if you visited any farms or open-air markets.
