What is a common symptom of Herpes Simplex?

Fever blisters, also known as cold sores, are a hallmark symptom of Herpes Simplex Virus (HSV) infections, particularly the oral form known as HSV-1. These fever blisters typically appear as small, painful vesicles that cluster around the lips or mouth, but they can also occur in other areas of the face. The virus can remain dormant in the body and may reactivate due to various triggers, leading to the recurrence of these sores.

Understanding this symptom is crucial, as fever blisters can be unsightly and uncomfortable. They serve as a visual indication of the virus's activity and can also be contagious. Recognizing fever blisters allows individuals to take appropriate measures to manage the condition and minimize its spread, such as practicing good hygiene and avoiding close contact during outbreaks.
