During an outbreak of avian influenza among poultry, there is a possible risk to people. Although the exact incubation period for bird flu in humans isn't clear, illness seems to develop within one to five days of exposure to the virus. The symptoms of avian influenza may depend on which virus caused the infection.

Symptoms of bird flu
For humans, the illness seems to develop within one to five days of exposure to the virus. But the main symptoms of H1N1 flu in people are similar to the symptoms of regular human seasonal influenza. Most people diagnosed with bird flu exhibit signs and symptoms of conventional influenza. Less often, diarrhea, vomiting, abdominal pain, chest pain and bleeding from the nose and gums also have been reported. Some people with H1N1 flu have reported having a runny nose, sore throat, nausea, vomiting and diarrhea in addition to the symptoms listed below. The main symptoms of avian flu in humans include:

  • coughing
  • exhaustion
  • fever
  • lack of appetite
  • lethargy
  • muscle pain

Complications
Some people diagnosed with avian flu also develop life-threatening complications such as viral pneumonia and acute respiratory distress syndrome. Acute respiratory syndrome causes the air sacs in your lungs to fill with fluid. This results in severe breathing difficulties. Morbidity and mortality statistics indicate that more than half the people who have contracted bird flu have died. The risk of developing a complication is greater if a person experiences additional chronic disease(s), such as diabetes, obesity, heart attack or heart ischemia, or asthma. Possible complications include:

  • acute respiratory distress syndrome
  • death
  • viral pneumonia

When to seek help
See a doctor immediately if you develop flu symptoms that last more than a week. These symptoms include a fever, cough and body aches. It is important for the doctor to be able to determine if a person has bird flu or some other flu variant. This becomes even more critical if you have recently travelled to a part of the world where bird flu occurs. Inform the doctor when and where you travelled and whether any farms or open-air markets were visited during this trip. This way, s/he can make a proper diagnosis as to whether or not the person has bird flu.  To learn more about how the doctor will make the diagnosis, read the next section on diagnosing bird flu now.
