How contagious is the illness? My fiancé  had a new employee start on Wednesday, well he arrived early and was hanging around the house while they waited for the rest of the employees to show up. Well once they left, I went to get breakfast, came back to the house, ate and watched some tv. After, I started doing laundry and cleaning the front of the house. Well, I'm 26 weeks, and just wondering how contagious it would have been? I go to the doctor on the 10th, and will definitely be bringing it up.
