Also known as Cold Sores, Fever Blister, Fever Sore, Lip Herpes, and Herpes Labialis
Herpes labialis, or orolabial herpes,:368 is an infection of the lip by herpes simplex virus (HSV-1). An outbreak typically causes small blisters or sores on or around the mouth commonly known as cold sores or fever blisters. The sores typically heal within 2–3 weeks, but the herpes virus remains dormant in the facial nerves, following orofacial infection, periodically reactivating (in symptomatic people) to create sores in the same area of the mouth or face at the site of the original infection.Source: Wikipedia
