Cold sores, also known as fever blisters, are a common viral infection caused by the herpes simplex virus (HSV). They are characterized by small, fluid-filled blisters that appear on the lips, mouth, or around the oral area. Once you have contracted the HSV, the virus remains dormant in your body and can reactivate, causing recurring cold sore outbreaks. In this article, we will explore what reactivates cold sores, the symptoms, and the most effective management and prevention strategies.
Introduction to Cold Sores and HSV
Cold sores are highly contagious and can be spread through skin-to-skin contact with an infected person. The initial infection often occurs during childhood, and it’s estimated that up to 80% of the population has been exposed to the HSV by the age of 10. After the initial infection, the virus retreats to the nerve cells, where it remains dormant. However, various triggers can cause the virus to reactivate, resulting in cold sore outbreaks.
