Warts that do not recur for six months may still have the virus, and there is still some chance of transmission. Warts are caused by HPV (human papillomavirus) infection, the incubation period of 1-12 months. If the warts don’t come back in six months, they may still be in the incubation period, and there may still be a virus in the body. So generally need to observe about a year, if there is no recurrence can basically rule out viral infection. HPV can be transmitted through sexual intercourse, blood, mother and child. If the warts do not recur for six months, it is recommended to do a good job of cleanliness and hygiene, and avoid unclean sex, so as to avoid the recurrence of the disease or lead to other people’s infections. The patient should go to the regular hospital for the relevant examination, so as to clarify the HPV infection.
