oh my gosh, I’m really sorry. I know you must feel sad. So you had sex with the person with herpes on the 5th and testing on the 16th? And your result is 3.7? I would say it is extremely unlikely that this is new infection, no. That’s only 10 days and that’s the earliest I have seen anyone in my practice go from negative to positive and their index value was 1.2. I would strongly suspect that this is NOT a new infection for you but rather an established infection. In fact, the bump to which you refer may or may not be herpes – you will likely find out soon, particularly if a PCR swab was taken.
The little bumps on the lip sounds like you got a mild case of HSV 1 as a young person. The person who has HSV 1 already and contracts HSV 2 may or may not have any apparent symptoms.
We recommend that any person with an index value of 1.1 to .3.5 get a confirmatory test and I have had patients with scores as high as >5 not confirm with a western blot. Crazy, huh? I know. If you want to be absolutely sure, I would recommend the western blot. If the western blot is positive then yes, go on suppression and even if you don’t and accept this as positive, you may benefit from suppression if you are having sex with an uninfected person.
