HPV is usually transmitted sexually through genital contact The chance of HPV transmission during sexual intercourse is not known, but the literature reports that it is about 65% or higher. Similarly, most studies find that 64-70% of women with cervical HPV lesions have sexual partners who can detect HPV lesions in the genitals when they are tested. The lesions are so small that the person may not even be aware of them. Usually, HPV is transmitted during sexual intercourse and can develop into genital warts over a period of about 4 weeks to 8 months, but some infections can remain latent and develop into warts or cervical lesions years or even decades later. So it is impossible to determine exactly when HPV infection has occurred. When one partner has HPV lesions, then both partners in a sexual relationship may be infected with one type of HPV at the same time. using condoms during sex can reduce exposure to the virus and can speed up the clearance of HPV. When the HPV viral load is reduced, your own immune system is able to clear the virus more effectively. Oral sex is also a route of HPV transmission. However, studies have found that a quarter of the squamous epithelium on the head and neck is at high risk for HPV, so HPV transmission from oral sex, although it exists, rarely causes serious disease. In addition to sexual intercourse, indirect contact, such as the use of toilets, doorknobs, soaps, swimming pools, and bath tubs, can also lead to the transmission of HPV. So it is transmitted in multiple ways, even into daily life. HPV 6 and 11 can be transmitted to newborns during vaginal delivery, causing warts in the upper respiratory tract or waiting area, but it is also rare, and a cesarean section can reduce this risk. If genital warts have been cured for more than 6 months, then vaginal delivery is even less likely to transmit HPV.
