I’m not in full agreement with your doctor. But if you go on suppression now, I don’t think the two-year statistic applies as you will be slower to make antibodies. But since you have an accurate swab test diagnosis, does it matter? Having said all of that, most people with genital HSV 1 don’t require suppression due to the infrequent recurrences that you will have, especially after the first year of having HSV 1. It would be fine not to take suppression right away, but you will be shedding more virus in the first six months or so of being infected, so if you are having sex with a susceptible partner, be sure to use condoms.
