Oral herpes refers to an infection of the tissues around the mouth with one of the two herpesviruses, herpes simplex virus 1 or 2. It is a very common infection that produces the characteristic cold sore or fever blister. The virus resides deep in the nerve roots and may reactivate at a later time, causing the same symptoms and signs in the same location. Oral herpes is also referred to as herpes labialis.
Signs and symptoms of HSV-1 infection include painful, sore lips with tiny fluid-filled lesions (blisters), ulcers, and redness. Other associated symptoms include tingling or burning pain in the lips. Symptoms go away within 1-2 weeks but often reoccur throughout life due to reactivation of the virus.
