The most effective method of avoiding genital infections is by avoiding vaginal, oral, and anal sex. Condom use decreases the risk somewhat. Daily antiviral medication taken by someone who has the infection can also reduce spread. There is no available vaccine and once infected, there is no cure.  Paracetamol (acetaminophen) and topical lidocaine may be used to help with the symptoms.  Treatments with antiviral medication such as aciclovir or valaciclovir can lessen the severity of symptomatic episodes.
