From Wiki:
A human papillomavirus (HPV) is a papillomavirus that infects the epidermis and mucous membranes (at the nostrils, the lips, the ears, the genital area, and the anus) of humans. HPV can lead to
cancers of the cervix, vulva, vagina, and anus in women. In men, it can lead to cancers
of the anus and penis. Approximately 130 HPV types have been identified. Some HPV types can cause warts (verrucae) or some types of cancer, while others have no symptoms. Most people who become infected with HPV do not know they have it.
Most scary is the virus is with u for life or u may kana some painful cancers!
Liked sogua said, it will return every few months to haunt u after the symptoms cleared.
