MAIN Arrow to HealthHealth Arrow to DiseaseDiseases & Conditions Arrow to Bird Flu Bird Flu

Chickens and other poultry
are the main culprits in
transmission of bird flu.

Warnings of the Asian bird flu, the newest strain of the flu, first appeared in areas around Hong Kong, Thailand and Vietnam in the late 90's.

The virus is a type of avian influenza virus. It is called that because the disease is primarily found in birds. Chicken, ducks, geese and other domestic poultry birds can be infected with the virus.

Scientists once believed it was impossible for humans to catch the Avian bird flu, but the flu virus proved very able at adapting to infect new hosts. A small outbreak in Hong Kong in 1997 announced that the Avian Influenza A virus had made the necessary changes to infect humans.

The H5N1 bird flu strain has since killed 360 people worldwide, mostly after contact with infected fowl. By 2012, outbreaks of bird flu were still being reported in China, India, the UK, and other areas where humans are in close proximity to poultry farms.

According to the World Health Organization since March 2013 a particularly dangerous strain of H7N9 flu has infected 108 people in China, with additional cases reported in Taiwan.

The H7N9 virus has been called "one of the most lethal" of its kind and transmits more easily to humans that any strain yet seen. Most worrisome to health officials is the strain's ability to remain undetected as it seems to cause few symptoms in the early stages.

Bird flu symptoms and treatment

Symptoms of bird flu in humans are typical of any flu. Some people have a fever with a cough, sore throat, and muscle aches associated with a bout of the flu. Eye infections and pneumonia are also common complications. In the most severe cases there may be extremely high fevers, difficulty breathing - and other life threatening complications.

Treatment and prevention of bird flu usually calls for antiviral drugs such as oseltamivir (Tamiflu) or zanamivir (Relenza) which are highly recommended for both prevention and treatment although with the latest H7N9 strain even these have been less effective than in the past.

Of course, the best preventative begins with avoiding exposure to live poultry farms where the virus is likely to be most prevalent.
