Bird flu, or avian flu, is an influenza virus *strain that typically infects birds - including wild birds like ducks and domestic birds like chickens. There are many forms of bird flu, and most are relatively harmless, producing mild symptoms or even no symptoms. However, several strains of bird flu produce a highly contagious disease that kills quickly and could lead to a massive bird flu epidemic. These dangerous viruses are known as "highly pathogenic avian influenza." One such bird flu virus is currently spreading among chickens in Asian countries. In recent years it was discovered that the bird flu virus can infect people who have close contact with live birds. The current strain cannot be passed from human to human, but health officials say it may mutate and become contagious in our species. "It's a little concerning because the virus is still trying new things in its evolution," said Perdue, who is overseeing the agency's response to the Turkish outbreak from World Health Organisation WHO headquarters in Geneva. Influenza experts are studying the apparent change to determine its significance, Perdue said. A spokesman for Britain's Medical Research Council, which is involved in the research, said it would take a few days to confirm the preliminary findings. If that happens, according to David Navarro of the U.N. and World Health Organization, "an epidemic could kill between 5 and 150 million people," which would be a much larger disaster than 2004's Asian Tsunami and 2005's U.S. hurricanes combined. There are many symptoms of bird flu (avian flu) in humans such as Cough, Fever, Muscle aches, Sore throat, severe cases of breathing problem and pneumonia. This disease is fatal. Anyone with bird flu symptoms should see a health care professional immediately. The bird flu virus currently infecting birds in Asia that has caused human illness and death appears to be resistant to Tamiflu, according to officials at Queen Mary Hospital in Australia. The drug which is the most common drug used to treat flu in humans. There currently is no vaccine to protect humans against the strain of bird flu virus that's been detected in Asia. However, research studies to test a bird flu vaccine to protect humans began in April 2005. *strain By George McKenzie ( internet source) A.
