Once someone gets HPV, the DNA related to that disease stays in your system forever. The same can be said for every virus that you've ever had.
If you want it straight from a doctor, you can dish out $20 and ask Dr. HHH or Dr. Hook, but they will tell you what I am telling you now: once your body has cleared the HPV virus, the likelihood of it ever showing up again, causing warts, or being infectious, is small. Only if your immune system suffers a drastic shock (an HIV infection, or chemotherapy related to cancer treatment, for example), is it actually likely to resurface. If your girlfriend has had clear pap smears, then I wouldn't be worried whatsoever.
Search the threads in this forum. I posted a link to an article that you may find interesting. It showed that among women who contracted a strain of HPV, the overwhelming majority of them 100% for HPV-6, 100% for HPV-11 and 100% for HPV-16, were shown to be clear of the virus three years later. By "clear", I mean that even by the most sensitive PCR testing, HPV was undetectable in their system. HPV is not likely to reactivate. For those with HPV-18, something like only 8% still had an active HPV infection three years after they contracted it.
Like I said, if you want peace of mind from facts, getting opinions from non-experts such as myself will do little good. Talk to your doctor, ask Dr. HHH a question, and so on. But I can tell you that every doctor I've talked to: two of my GPs, my dermatologist, and Dr. HHH have told me that HPV is transient, and it is very unlikely to re-activate down the line in the absence of some immunodeficiency event.
Thanks for the reply, however I have read that once a person gets a HPV it stays in the system for life, can resurface in the future and can be passed on...I'm just trying to figure out where the facts are on this...it's kind of all over the place.
Congrats on having a good attitude about HPV. You're right in that just about everybody gets it (and if you have had sex in the past, then chances are good that you've had it already too.)
Now, as far as your girlfriend goes... 10 years ago? I'd say it's a very safe bet that her HPV is loooooong gone. A large proportion of genital wart causing HPV infections clear up within a few months (maxing out at two years). The non-wart causing strains usually last a little longer, but typically not longer than three years. Provided she has had clear pap smears and hasn't had any warts for 10 years, then I'd say the chances are extremely, extremely tiny that she would pass any HPV to you considering she has been "cured" of the virus for quite some time. Equally unlikely that she would pass HPV along to children.
I'll put it to you this way... the chances of her passing you her HPV infection seem almost equally as likely as she is to pass you a cold virus that she had in 2002.
If I were you, I'd go forward and not worry about HPV with her. Of course, you could always get vaccinated too, and then you REALLY wouldn't need to give it another thought.
