I would like to help, but it is impossible for me to predict a) whether or not the new lesion you describe is a wart or b) whether you still could transmit HPV to a sex partner. If it was a wart, you can assume you are infectious. If not, you may or may not be infectious; on average, it is likely that most people with genital warts cease to be highly infectious within a few months after the warts resolve, and your doctor's advice sounds like the same I would give. But there simlply is no way for any particular person to know with certainty.

My personal perspective is between those two, but closer to the latter. People with known active infection or recent infection probably should tell their partners. But most people who have had genital warts or other HPV infections become non-infectious after a period of time, probably usually a few months. And treatment of warts probably reduces infectivity, although this isn't proved.
In general, I tell my patients that once their warts have resolved and have not recurred after 6 months, or 6 months after the last normal pap smear, they no longer need tell potential partners. But some users of this forum, and some very well meaning and knowledgeable STD experts, disagree with me. There is no definite answer.
