My cubemate had a 106 degree fever over Christmas, and could not get out of bed without collapsing! DAMN! He did give it to me last week before we left for Christmas, but I rested early and often, and mega-dosed vitamin C and other vitamins. I only ended up with a cough, 100 degree fever, and a few aches for two days. All except for the cough are gone now, and I feel fine.
