about transmission using arvs and condoms.
I'll link more soon.
Studies about transmission always involve one partner who is negative and another who is positive. In every study, the people at the end who didn't use condoms and are still negative are scientific proof that these couples exist. Anecdotally, I also came across numerous women in midwifery who were positive with a negative partner or vice versa. Those whose partner tested positive were advised to use condoms because pregnancy compromises your immune system. Lots of those women would be tested and would be negative for the type of herpes their partner had.
