HPV oral and oropharynx infection dynamics in young population.

The incidence of human papillomavirus (HPV)-associated cancers, especially those from the head and neck region, has increased. The relatively early age of presentation of HPV-positive head and neck cancer (HNC) indicates that viral infection might be acquired early in life. Persistent HPV infection has been recognized as the main risk factor for cancer development, but most studies have focused on evaluating HPV persistence in the genital region.
