Anal Warts

What are anal warts?
Anal warts develop around the anus and genital area. They can affect the skin both on the outside and the inside of the anus.

What causes anal warts?
Most anal warts are caused by the human papilloma virus (HPV). This is usually transmitted by person-to-person contact and as such if often regarded as a sexually transmitted disease. You do not necessarily have to have had anal intercourse to develop anal warts.

People who are immunosuppressed are at greater risk of developing anal warts. People may be immunosuppressed because they are taking drugs to suppress their immune systems such as transplant patients. Other causes of immune suppression include HIV (Human Immunodeficiency Virus) infection.
