Understanding Human Papillomavirus (HPV) and Genital Warts

Human papillomavirus (HPV) is a virus that causes warts. It can be hard to detect, so many people never even know they have it. Some strains (types) of HPV cause warts on the hands. These are harmless. Other strains of HPV cause warts in the genital area. Of these, a few strains can lead to cancer in the cervix (where the uterus and vagina meet) and the genitals. Treating genital forms of HPV now can help prevent serious health problems in the future.

How Was I Infected?

HPV is passed from person to person through contact with infected skin. Everyone with HPV has a different experience. Some people notice genital warts (condyloma) within a few months of exposure. In other people, warts take years to appear or may never appear. This makes it almost impossible to know when or by whom you were infected.

How Warts Form

HPV lives inside skin and mucous membrane. The virus can make skin cells reproduce more often than they should. These extra skin cells build up into warts.

  1. HPV invades the skin.

  2. DNA from the virus enters skin cells.

  3. HPV causes infected skin cells to multiply and form warts.

  4. The virus sheds, enabling it to be passed to others.
