Most people are infected with certain genital types of HPV during sexual intercourse and get subclinical infections caused by HPV on the skin and mucous membranes of the genital organs, during certain phases of their life.
The chances of becoming infected with HPV and developing subclinical lesions are proportional to the number of sexual partners. The sexual history of each partner and the use of a condom also play an important role.
The incidence of subclinical lesions is many times higher than the incidence of genital warts. The latter is calculated at 1-3% of individuals who have not been vaccinated.
