The flu is not just a bad cold. If the fever, chills, cough, sore throat, congestion, muscle and body aches, headaches and fatigue weren't misery-making enough on their own, the illness can spark some nasty complications.
A fever enables the body to increase its production of interferon, an important antiviral substance that is critical for fighting infection. Fever also increases white blood cell mobility and activity, which are instrumental factors in fighting infection.
"Epidemiologist gets swine flu" is not as catchy a news headline as "man bites dog" but it is cut from the same ironic cloth. My swine flu was not a lovable affair, it was not a joke, and it was not "mild."
