So if u have type 2 herpes and the other person doesn't they will get it for sure?

Herpes 2: Nope. If you do not know where you are infected then it may be wise to start a daily medication to lower your viral shedding and make you less contagious. The medication is valacyclovir.

Nothing is for Sure!: With repeated exposure, the other person is much more likely to get herpes 2 virus but there are many factors involved. If it is a single encounter, they may not, but with repeated contact it is more likely than not that they will eventually get it - esepcially during unprotected sexual activity but even with protection, it can be passed.
