I feel guilty and worry that I may have transmitted the virus to my partner

There is no reason for such feelings. HPV infection is very common, as there is an 80% chance of becoming infected with one or more types of HPV during one’s lifetime. The difference between you and other people is simply that you know about it. Most people infected by HPV have no symptoms, the infection is automatically suppressed by their body, and they never know about it. The diagnosis brings anxiety and guilt, even though you did nothing wrong!
