Condoms protect only what they cover, leaving scrotum, anus, and other skin surfaces exposed to the virus. Once infected, a person always has the virus. There is some risk of infecting others even when there are no visible warts. Genital warts cannot spread to the hands, abdomen, feet or other places. These are caused by a different wart virus.
More warts can grow and then they can be harder to get rid of.
Especially for women, warts can lead to precancerous conditions. Genital warts are usually diagnosed by history, location, and appearance. Genital warts cannot be cured. Even after the wart tissue is destroyed, the virus remains and warts can reappear months or years later. Usually, you will need to return for several treatments.
