I'm so sorry your roommate v*ed and upset you. She seems to v a lot. She can't have sv all the time. There's not that many strains out there. Could she possibly have an ulcer or some condition which causes v? As an outsider looking in, it just seems like she is either pregnant or has some sort of condition. This much v is not normally a part of life. Even my relatives who get noro every time it comes around only have it a couple of times a year. They certainly don't get it several times in a month. I'm not a doctor, so I can't say, but it seems like there is something else going on with her. In other words, I don't think you are contaminated. I think your roommate has some sort of a condition.
