An infection caused by a virus that can cause blisters or sores.
Some people have no symptoms at all. But many people get blisters or sores on their lips, inside the mouth, or on or inside the vagina, penis, thighs, or buttocks. These blisters or sores are different for everyone – some people only get them once; other people have "outbreaks" many times over their lifetime.
You could pass it on to your partners, even if you don’t have sores or blisters when you have sex. Infection increases your likelihood of getting HIV.
