Hello. Thank you for writing to us at healthcaremagic Hpv is the cause of genital warts. Hpv infection may be clinically silent at a particular point of time i.e even though the patient carries Hpv infection there may not be any obvious genital warts. Now, since the lady in question tested negative at ten weeks but later tested positive for Hpv therefore it is likely a recent infection in her and probably she got it from your boyfriend, provided she does not have any other sexual partners. I suggest you to get tested for Hpv as a precautionary measure. In females, Pap smear can detect Hpv viral DNA and therefore you may take up a Pap smear test. Though there are no tests approved for detecting clinically silent Hpv infection in males with no obvious warts, Regards
