A nasopharyngeal culture is a sample of secretions from the nose and throat taken with a cotton pad in a laboratory-bred and examined microscopically for the presence of avian influenza. This test can be used to detect the influenza virus and determine the strain, but the results of the tests can for as long as 3 days.
You can get the typical flu-like symptoms with high fever, headache, muscle aches,Exhaustion, but also get many of the cases, the involvement of a rapidly progressive lung and lung, where the respiratory disease, respiratory distress, and this is usually the cause of death or a contributory cause of death in people who 'actually from died've avian influenza.
