Patient: Hello, I recently got over what I believe is a bad bug. I was vomiting, lethargic, couldn’t keep anything down for the first day. My appetite was gone today’s after. I recovered within three days, and went over to my boyfriends house. It seems that he also got this bug, but it’s way worse. He’s been vomiting profusely for one day, and now it’s on and off on the second day. He still very lethargic, and extremely achy. He’s running a bit of a fever, and I’m really worried about it. What should I do?

Doctor:
