Common viral infections include cold sores, also known as fever blisters. These are small, fluid-filled blisters that form around the lips. These blisters can often be found in clusters. A scab can last for several days. The majority of cold sores heal within two to three days without leaving scarring.
Cold sores can spread by contact such as kissing. Herpes simplex virus type 1 (HSV-1), but less often herpes virus type 2 (HSV-2), are the most common causes. These viruses can cause severe infections in your mouth and genitals. They can also be transmitted by oral sex. Even if you don’t see them, cold sores can spread to others.
