[Question #13638] HSV

Hello Terri, I’m a male with a single potential HSV exposure on 8/29 involving protected vaginal sex and protected oral sex, and I have no history of cold sores. I’ve had multiple HSV IgG tests using the Roche (Elecsys) assay that were all negative for HSV-1 and HSV-2 at 31, 42, 52, and 82 days post-exposure. My wife is pregnant and due fairly soon, and at the time I believed I was HSV-negative due to having no symptoms; we had unprotected sex on 10/1 (33 days post-exposure) and 10/17 (49 days post-exposure), and she has had no symptoms. My questions are: (1) how reliable are repeated negative Roche HSV IgG results at these time points in ruling out infection, (2) given protected oral and vaginal sex as a male, how confident can I be that my 8/29 exposure was truly low risk, (3) based on this timeline, does this situation fall outside the typical window of concern for neonatal HSV transmission, and (4) given all of the above, would you consider my risk low enough that no further HSV testing or action is needed?

The Roche test is as good as it is going to get at 82 days out - close to three months.  Your experience in August was truly low risk, given consistent condom use.  The other factor here is that you've had no symptoms, at least that you've reported here, suggesting that you acquired either HSV-1 or HSV-2, although the Roche test does miss 15% of HSV-1 infections compared to the Western blot.  I take it you've never had a cold sore on your lip or in your nose in the past?

I’ve never had a cold sore or any classic HSV blister-type lesions, orally or genitally. For ~3 weeks I’ve had a small, flat area in the pubic hair region that has not blistered, ulcerated, crusted, or changed in size; it fluctuates between slightly pink and normal skin color, causes no pain, and shows no typical herpetic progression, though I’m aware HSV can present atypically. I’ve also had brief, random sharp or nerve-like pains lasting seconds in the pubic area, testicles, or glans that shift location, are not followed by lesions, and seem to occur mainly when sitting, possibly related to anxiety. I’ve had multiple Roche (Elecsys) HSV IgG tests negative for HSV-1 and HSV-2 at 31, 42, 52, and 82 days post-exposure, and I’ve had no harsh initial genital outbreak. Based on this, I wanted to ask: - Is it reasonable to view the repeatedly negative Roche result at 82 days as strong reassurance against HSV-2? - Given the lack of a significant initial outbreak plus negative Roche testing, does this make genital HSV-1 unlikely despite the known miss rate? - Do the described skin finding and transient, shifting nerve-type pains sound consistent with herpes in your experience? - At this point, would you consider further HSV testing or action necessary?

The skin lesion you describe sounds absolutely nothing like HSV to me.  Herpes would very rarely last for three weeks, and if it did, it would start with water
 blister-like lesions that would break open, ulcerate, then scab over and be at least tender, if not painful.  A dermatologist might be able to tell you more specifically
what those areas are.  I don't think anything you've added here would impact the 15% miss rate for HSV 1 on the Roche test.  Also, I don't think the nerve-like pains
that you describe are consistent with HSV either.  If you want more certainty about your herpes status, you could do the herpes western blot, but I think we can be
quite certain that you don't have HSV 2 at this point
