Hi there. I am currently ill with a bad chest/head cold and fever. Well, the fever comes and goes. I have not taken anything for it since last night at 9pm and it is now 11:30am, Pacific time, and my temp is normal. However, the fever sometimes creeps back, as it did last night before going to bed. I have a 15-month-old son I am largely avoiding so he doesn't get sick. He had surgery on the 12th of Feb and has a follow-up procedure on the 18th of March - a stent removal they won't do if he's had a cold within two weeks of the procedure. Are there some general rules about how long I'm contagious? I've been ill since Friday night and he still seems fine. (knock on wood)
