What if I don't get treated for genital herpes?

Some herpes viruses can cause meningitis or encephalitis. HSV encephalitis is mainly caused by HSV-1, whereas meningitis is more often caused by HSV-2. Herpes viruses have been linked to Recurrent Lymphocytic Meningitis (Mollaret’s meningitis), which is characterized by sudden attacks of meningitis symptoms that last for 2-7 days and are separated by symptom-free (latent) intervals lasting for weeks, months or years.
