Treating your viral warts while they are still small may help prevent them from spreading. Your doctor may have imiquimod cream applied to the treated areas to help prevent recurrences by stimulating local immunity to human papillomavirus(HPV).However, this is not proven. For prevention of ano-genital warts(condyloma acuminata), it is key to practice safe sex which may include use of condom during sex and avoiding sexual contact with affected people.
