Herpes simplex

Definition

Herpes simplex is an infection that mainly affects the mouth or genital area.

Causes, incidence, and risk factors

There are two different strains of herpes simplex viruses:

  • Herpes simplex virus type 1 (HSV-1) is usually associated with infections of the lips, mouth, and face. It is the most common herpes simplex virus and most people develop it in childhood. HSV-1 often causes lesions inside the mouth, such as cold sores (fever blisters). It is transmitted by contact with infected saliva. By adulthood, up to 90% of people will have antibodies to HSV-1.
  • Herpes simplex virus 2 (HSV-2) is sexually transmitted. Symptoms include genital ulcers or sores. In addition to oral and genital sores, the virus can also lead to complications such as infection of the lining of the brain and the brain itself (meningoencephalitis) or infection of the eye (especially the conjunctiva and cornea). However, some people have HSV-2 but do not show symptoms. Up to 30% of U.S. adults have antibodies against HSV-2. Cross-infection of type 1 and 2 viruses may occur from oral-genital contact.

A finger infection, called herpetic whitlow, is another form of herpes. It usually affects health care providers who are exposed to saliva during procedures. Sometimes, young children also can get the disease.
