Papillomavirus

特許 権利維持 Human papillomavirus (HPV) is a DNA virus from the papillomavirus family that is capable of infecting humans. Like all papillomaviruses, HPVs establish productive infections only in keratinocytes of the skin or mucous membranes. Most HPV infections are subclinical and will cause no physical symptoms; however, in some people subclinical infections will become clinical and may cause benign papillomas (such as warts [verrucae] or squamous cell papilloma), or cancers of the cervix, vulva, vagina, penis, oropharynx and anus. HPV has been linked with an increased risk of cardiovascular disease. In addition, HPV 16 and 18 infections are a cause of a unique type of oropharyngeal (throat) cancer and are believed to cause 70% of cervical cancer, which have available vaccines, see HPV vaccine.
