Genital warts are caused by the HPV infection when a person has unprotected sex with someone who is carrying the infection or is already infected. This is sexually transmitted from one person to the other and when a person gets treated the partner or partners should also undergo treatment to prevent re-infection.
The human papilloma virus or HPV which causes warts in the genital areas has more than a 100 categories of the infection and among these at least 40 can cause infection and warts in the genital area. Genital warts are caused mainly by HPV-6 and HPV-11 and also have the potential for causing cancer though not a very heightened one. There are various other HPV strains which do cause cancer in women in the cervical region and also pre-malignant changes.
However, once the diagnosis has been made with the appearance of warts in the genital area the person has to have the warts removed either with medication or surgically to avoid the infection from spreading around the area and causing more warts to grow. All persons who have unprotected sex or any other kind of sexual contact with a person who has the infection will develop genital warts within two to three months of the act. Persons who are on the birth control pill are more prone to genital warts and sexually transmitted diseases as they have unprotected sex and do not use condoms. Often such persons are prone to having sex at an earlier age and also because there is no fear of pregnancy, they have several sexual partners.
