Herpes Simplex Virus

What is Herpes Simplex Virus?

There are two types of Herpes Simplex Virus (HSV): HSV-1 and HSV-2. HSV-1 has manifestations above the neck (i.e. the face, such as mouth sores) and is not an STD. HSV-2 causes genital herpes.

Signs & Symptoms

While 90% of adults have been exposed to HSV-1 by the age of 21, the virus often remains dormant therefore causing no symptoms. Active inflammations from HSV-1 may affect the eye casing lid swelling, crusting, redness, and/or decreased vision.


The Herpes Simplex Virus is treated with topical or oral anti-viral medication. Some patients are left on these medications long-term to prevent reactivation of the virus.
