Chances of getting stomach virus?

Its now about 33 hours after krista had started the stomach bug. i had no symptoms at all, i was just nervous (still am) i have a phobia about getting sick. i have not left my room since. only to use my private bathroom outside my room that nobody else uses. i used clorox bleach wipes on my desk in my room. do you think i am going to get it if i wasn't around her at all? i want to stop worrying.
