About Cold Sores and How to Treat Them

Cold sores are small, fluid-filled blisters that usually appear around the lips or mouth. They are caused by the herpes simplex virus (HSV-1), which remains dormant in the body and can reactivate due to triggers like stress, illness, or sun exposure.
Yes, cold sores are highly contagious and can spread through direct contact with an active sore or shared items like utensils or towels.
Cold sores typically last 7–10 days. Antiviral treatments can speed up healing and reduce symptoms.
