Thanks for your question and concern. As you may know, genital warts is caused by HPV or human papilloma virus. It causes genital warts and cervical cancer in females, according to the type of virus. Taking a Gardasil vaccine can help preventing getting affected by type 6, 11, 16, and 18 of HPV viruses in young women of your age. HPV vaccination is an injection given in a series of 3 shots in muscles of upper arm or thighs. First shot of Gardasil can be taken when a girl is 9 to 26 years old. Then following shots of vaccination is to be taken 2 months after the first injection and the third injection can be had after 6 months from the first injection. You can take this injection even if you are found positive with HPV or found abnormal pap smear in past. Anyway, this cannot be used to treat active warts and cancers and also will not cure a HPV infection. As you may know, genital warts can be spread easily from one person to another through skin to skin contact itself, being very contagious in nature. There is a high recurrence rate also, causing a recurrence at more than 50% of times, after a year from the first outbreak. The process of recurrence can be speeded up by continuous sexual contact with affected people. The virus remain there in the hair follicles while the infection is in its dormant state. There are various methods of destroying the virus as they stay dormant in the superficial skin layers. Cryotherapy using super cooled liquid nitrogen, electrocution of affected cells, surgical excision of affected cells are the major ways of removing virus. Anyway, these processes are risky and have undesired side effects. They are done under local, regional or general anesthesia at times. Laser treatment is found to be the most effective even though the treatment is very costly and cause scarring and takes long time for healing. However, not method has been found yet to completely remove or destroy virus, if it is affected once. No treatment is found to be 100% fool proof in preventing a recurrence. Ways of preventing getting affected are, using condoms and refraining from sexual activities with affected people. Anyway, the former is not proved effective in some cases as the skin having virus can spread the virus to sex partner, by just being in contact.
