I'm in college, and the boy i'm currently seeing had a s*v* on Sunday evening, Jan. 31. It was a 24 hour thing, and he's not sure if it's something he ate or an actual virus.
Yesterday Feb. 3,we spent some time together for the first time since he's been sick, and I was a complete, anxious, mess. He convinced me that he was fine and not contagious, and we spent the night together, kissing & whatnot.

How probable is it that he's still contagious? I am petrified of becoming sick, and today I've been having really bad stomach aches.
