Cold sores, also known as fever blisters, are a prevalent viral infection caused by the herpes simplex virus type 1 (HSV-1). After the initial infection, HSV-1 remains dormant in the body and can reactivate due to factors like stress, illness, or sun exposure. This reactivation leads to the formation of painful blisters, typically around the lips, but they can also appear on the nostrils, chin, or inside the mouth.
