Reported January 2008

WHAT IS THE FLU: The flu is caused by the influenza virus, which targets the respiratory tract by binding to the surface of cells. Then the virus releases its genetic information into the cell's nucleus to replicate itself. When the cell dies, those copies are released into the body, infecting other cells. Flu symptoms are unpleasant, but not life threatening by themselves. However, the flu weakens the immune system, making the body vulnerable to more serious infections, such as pneumonia. Because the flu is caused by a virus (as opposed to bacteria) antibiotics are not an effective treatment. Both the flu and the common cold are best treated by bed rest, consuming lots of fluids and taking over-the-counter medication to ease symptoms until the virus runs its course.
