It's caused by the herpes simplex virus, usually type 2. The virus enters your body through small breaks in your skin or mucous membranes. Vaginal or anal sexual intercourse is the typical way the virus is transmitted. You can also infect your eyes by touching them with a contaminated finger.
Pregnant women can pass the virus to their babies during vaginal delivery.
Recurrent outbreaks Genital herpes is very contagious when sores are present. However, the virus can also be transmitted even when there are no visible lesions. Avoid sexual activity. Save sexual intercourse for times when you have no signs or symptoms. Limit your sex partners.
