Herpes Simplex Virus (HSV)

What is Herpes Simplex Virus?

Herpes Simplex is a virus that is transmitted through oral secretions or skin-skin contact. There are two types of Herpes Simplex Virus (HSV): HSV-1 and HSV-2. HSV-1 is usually associated with symptoms above the neck such as cold sores in the mouth, and HSV-2 is usually associated with genital herpes, however both types can appear anywhere based on exposure. When the eye is affected it is usually by HSV-1, and can be called Herpes Keratitis.

Signs & Symptoms

Herpes Simplex Virus can cause blisters that then erupt into painful sores on the skin. When the eye is affected (Herpes Keratitis), a person may experience lid swelling, crusting, eye redness, and/or decreased vision.

While 90% of adults have been exposed to HSV-1 before the age of 21, the virus often remains dormant and causes no symptoms. It is important to note that HSV-1 and HSV-2 can be transmitted even if there are no active symptoms. Outbreaks or flare-ups, during which sores appear, can occur, and can be brought on by general illness, fatigue, stress, immunosuppression, trauma or injury, and menstruation.

Treatment

Herpes Simplex Virus is treated with topical or oral anti-viral medication. Some patients are left on these medications for a long time – months to even years – to prevent reactivation of the virus.
