If a doctor treated you for genital warts, get retested at regular intervals for them and for HPV. This will help ensure that the virus and disease have left your system and that you are no longer contagious. Recurrence of genital warts is common and is often treated with the same course of medications. The best way to treat genital warts is to avoid getting them. Using latex or polyurethane condoms and limiting the number of your sex partners will minimize your risk for contracting the disease or having a recurrence.  Always use condoms during sexual contact. Although condoms will not eliminate your risk of getting warts, they will decrease your risk. If you have oral sex, use a condom or dental dam.  The more sexual partners you have, the higher your risk of getting genital warts is. Try and limit the number of partners you have to decrease your risk, and always use condoms with your partners. Doctors are not sure why, but being a smoker may make you more likely to contract genital warts. This may be because smoking suppresses your immune system. Being a smoker can also increase your likelihood of a recurrence. Try and avoid smoking for your overall health if possible. There is now a vaccine available that can protect against the strains of HPV which cause genital warts. If you or your child is between the ages of 9 and 26, consider getting the Gardasil vaccination to help avoid contracting genital warts.  Be aware that Cervarix, which also protects against HPV, does not protect against genital warts. Getting the vaccination may reduce your risk of getting genital warts by 50%.
