Herpes
Herpes
Herpes (/ˈhɜːrpiːz/, from the Greek 'herpein' meaning to creep or crawl) is a viral disease caused by the Herpes simplex and Varicella zoster viruses.
Etymology
The term "herpes" comes from the Greek word "herpein," which means "to creep or crawl." This refers to the unique characteristic of the viruses to "creep" along nerve pathways to nerve clusters at the end, where they remain in a latent state for variable periods.
Types
There are two types of Herpes simplex virus:
- Herpes simplex virus type 1 (HSV-1), also known as oral herpes, can cause cold sores and fever blisters around the mouth and on the face.
- Herpes simplex virus type 2 (HSV-2), is sexually transmitted and is usually associated with genital ulcers or sores.
The Varicella zoster virus (VZV) causes chickenpox and shingles.
Symptoms
Symptoms of herpes include painful blisters or ulcers at the site of infection. The blisters eventually break and leave painful sores that may take weeks to heal.
Treatment
While there is no cure for herpes, antiviral medications can prevent or shorten outbreaks.
