Jeez, sorry to read that Peter. When my late wife worked the university she was forever picking up colds and flue from the students many of whom had no idea of how to look after anything, let alone their health, many of whom were living away from home for the first time in their lives.. Mrs L being such a kindly soul was ever being told not to mollycoddle them as they had to get used to being responsible citizens...
Hope you feel better soon.
