Bird Flu Causes Symptoms Information with Treatment

Influenza viruses also are more contagious and cannot be as readily contained as SARS by isolating people who have the infection.

Although their symptoms are similar, SARS is caused by completely different viruses.  Scientists fear the bird flu virus could evolve into a form that is easily spread between people, resulting in an extremely contagious and lethal disease The two viruses could recombine inside the victim's body, producing a hybrid that could readily spread from person to person. The grimmest scenario would be a global outbreak to rival the flu pandemic of 1918 and 1919, which claimed millions of lives worldwide. For now, researchers are trying to develop a vaccine that would protect people in the event of a bird flu pandemic.

Treatment of Bird Flu

Antiviral medications used to treat human flu viruses help to reduce the symptoms of bird flu, but it's not yet clear whether these work for the current type of bird flu.

Oseltamivir (brand name Tamiflu) and zanamivir (brand name Relenza) antiviral medications used to treat regular flu may be helpful in the treatment of bird flu.

However, their effectiveness against the H5N1 subtype of the virus is uncertain, and there are also concerns about the availability and cost of these medications.
