Genital herpes is a common infection caused by the herpes simplex virus (HSV), which is the same virus that causes cold sores.
Some people develop symptoms of HSV a few days after coming into contact with the virus. Small, painful blisters or sores usually develop, which may cause itching or tingling, or make it painful to urinate.
After you've been infected, the virus remains dormant (inactive) most of the time. However, certain triggers can reactivate the virus, causing the blisters to develop again, although they're usually smaller and less painful.
It's easier to test for HSV if you have symptoms. Although there's no cure for genital herpes, the symptoms can usually be controlled using antiviral medicines.
