Primary Herpes Simplex Infection
What is Herpes Simplex?
Herpes simplex is a common viral infection caused by the herpes simplex virus (HSV). There are two types of HSV: HSV-1 and HSV-2. HSV-1 is primarily responsible for oral and facial infections, including cold sores, while HSV-2 is commonly associated with genital infections. Both types can spread to various body parts, including the mouth and genitals, through close contact such as kissing or oral sex.
What are Cold Sores?
Cold sores, also known as fever blisters, are small, fluid-filled blisters that typically form on or around the lips. They are caused by the HSV-1 virus and are highly contagious. These blisters often appear in clusters and can cause significant discomfort. After the blisters break, they crust over and usually heal within two to three weeks without leaving scars.
