As I understand your note, you have had a single lesion on your back that was cultured and found to be HSV-2. In addition, you have a blood test which indicated you have both HSV-1 and HSV-2. With these assumptions in mind, let's go to your questions:
1. Absolutely. You can get HSV-2 at any site that might have had contact with an infectious lesion. I have seen HSV-2 lesions on the thighs, the buttocks, the abdomen, the breasts and the back. If you have the infection with HSV-2 at the site on your back, the chance of you having genital or oral infection with the same virus is miniscule.
2. The assumption is incorrect. If you have HSV-2 on your back, you will not have genital HSV-2. Conversely, if you had HSV-2 genitally, you would not have it on your back. The culture says it is on your back. So be it!
3. Correct
4. The fact that your husband has not gotten HSV-2 is further evidence supporting the idea that your HSV-2 infection is unlikely to be on genitals.
5. Yes, recurrence very much tend to recur in the same general area that the initial infection occurred at.
Hope these comments help. EWH
Thank you for that information!! Just 1 more question:
Is it possible to have the HSV-1 on my back at the same place I have the HSV-2?
