Hello -- I believe this might have been answered previously, but I am curious if there are any studies/indications on what the percentages are of HPV transmission and ultimately the outbreak of genital warts are with repetitive unprotected sex with the same partner when one partner has a genital wart? For example, (using completely random numbers) - is it 70% of partners will be infected and 25% of those infected will end up with genital warts. 

Welcome to the forum. Thanks for your question. I’ll be glad to comment although, unfortunately, the per exposure transmission rate of HPV infections is unknown.  This is, in large part because HPV infection so so very wide spread.  As is the case for all other STI’s, the infection rate following a single exposure is certainly less than 50%, but more precision is not possible.  It is known however that in just one year following initiation of intercourse with a single partner, on average over 25% of women will be infected.  Common sense tells us that with more exposures, the cumulative infection rate increases.  There are even fewer data available regarding HPV acquisition in men than in women.---

Thank you for your reply. I have a couple of follow-up questions: 

Your follow-up,questions are related.  When warts appear they test to stay where they appear and not spread.  Auto inoculation due to touching, scratching or otherwise being spread by the hands is quite rare.  I’m not sure I’ve seen a case.  Warts can expand and spread when abraded however, such as when a wart and surrounding areas are shaved with a razor.  This is not till uncommon, occurring when individuals shave their penis and inadvertently shave a wart and the surrounding area as well.---

Thanks for your response and help. The issue on my thigh I just noticed - I have a follow-up appointment to have that looked at. 

Great. I would encourage you to do so. Normally if this is my third reply I would close this thread at this time however I am interested in what your dermatologist says about the lesion on your thigh. Therefore I will keep this thread open.  As I mentioned, there are many other processes which can occur in that area which are not HPV.---

Hello - I wanted to get back to you on the wart on my thigh. The biopsy came back as “…an old Verruca Vulgaris (wart) which is benign and has been completely excised.” Vs the biopsy of the other wart which came back as condyloma acuminatum (but without a type.)

Thanks for your thanks.  FYI, Veruca vulgaris is a "common wart" which, while caused by HPV is often not caused by the HPV types which cause genital infections.  There are >100 diffferent types of HPV.  This lesion may not have been genitally acquired.  Further, in that it is excised, I would consider you cured for this lesion.---
