Did a paper on this topic in college. If I recall correctly, one in six people carry the virus with no symptoms (lies dormant in the spine) and never know it. Unless you ask to be specifically tested for it....I don't think they check for it. I interviewed a doc and she told me that they don't test because once people know they carry the virus they become so stressed out, they have an outbreak. (not sure if that is a general rule or just the individual doc's policy.).

Also, I thought I read that "shedding" is also a very contagious time and there is no liquid contact involved there.

Being educated is a very good idea. Condoms even better idea.... but as someone else said....doesn't protect you during oral.

Just my .02 cents worth.
