Human papillomavirus (HPV)-associated oropharyngeal cancer awareness and prevention is a vital concept from a public and community health perspective. HPV is the sexually transmitted virus that is known to be the cause of genital warts. There are currently more than 100 different strains of HPV, half of which can cause genital infections. [1]
Some HPV types, such as HPV5, may establish infections that persist for the lifetime of the individual without ever manifesting any clinical symptoms.
