Welcome back to icliniq.com. It would be helpful to know which antibody is positive for your fiance. Is it HSV 1 or HSV 2? Also as I recommended earlier it would be very helpful to see which type you have either type 1 or type 2. If you both have the same subtype then it is highly likely that it was transmitted between you two. If it is different subtype (serodiscordant couple - one is positive and the other is negative) they you can still transmit the other subtype. For example, yours is HSV 1 and he is HSV 2 then you both can transmit it to each other through any type of sexual contact. Kissing may transmit it with oral lesions; similarly females are more likely to harbor ulcers in unseen areas (like cervix or vagina) and can transmit it as well. Regarding treatment, you can use Acyclovir or Valacyclovir if you want but it will only suppress the virus as long as you take it, once you stop taking it the virus will surface again. It does not go away and only hides. That is the reason that we treat patients with active lesions or they have more than three to four episodes a year. It is the delivery that makes things difficult if you have active lesions; that is an absolute contraindication to vaginal delivery since the new born can have serve eye infection and blindness. In case you get married to someone else, they will not know that you are HSV 1 or 2 positive unless they look for it. As I mentioned earlier, most of us have HSV 1 and it is very common. It can be even transmitted between mother and child, if you kiss your child on the lips to show extreme love and affection while having very minimal lesions on the lips.
