Human papillomavirus, or HPV, is a virus estimated to infect up to 80% of the general population over the course of your lifetime. HPV affects both women AND men and is transmitted from skin-to-skin contact usually from sexual contact. The virus can be present from the first sexual experience, though it may take much longer before it shows up on an exam. In many cases, a healthy immune system will clear the infection before it causes any problems; however, if the virus lingers it may cause complications. Consequences of HPV infection in women include, but are not limited to genital warts, abnormal pap smears, and in extreme cases genital cancers of the cervix, vulva, vagina, anus. Smoking and immunodeficiency will increase your risk of cancer in the presence of HPV infection.
