Unraveling the Origins of Cold Sores: A Comprehensive Guide to Oral Herpes
Cold sores, also known as oral herpes, are caused by the reactivation of the herpes simplex virus (HSV-1) in the body. Triggers for cold sore outbreaks include fever, UV exposure, stress, hormonal changes, immune system changes, and skin injuries. The virus is commonly spread through saliva, such as through kissing or sharing utensils, and most Americans are exposed to it during early childhood. It is estimated that 50 to 80 percent of adults in America have oral herpes. Despite the stigma associated with cold sores, they are incredibly prevalent, and individuals should not feel ashamed or isolated because of them.
