Herpetic whitlow is a viral infection of the hand, usually on the fingers, caused by the Herpes simplex virus. It is a painful infection that typically affects the fingers or thumbs. Occasionally infection occurs on the toes or on the nail cuticle.

Causes

Herpetic whitlow can be caused by infection by HSV-1 or HSV-2. HSV-1 is usually associated with oral herpes, but can also cause genital herpes. HSV-2 is typically responsible for genital herpes, but can also cause oral herpes.

Symptoms

The symptoms of herpetic whitlow include swelling, redness and pain. Blisters may also form on the fingers, and in some cases, the blisters may be filled with clear fluid. The symptoms usually appear one to two weeks after a person has been exposed to the herpes simplex virus.

Diagnosis

Herpetic whitlow can be diagnosed by a physical examination. The doctor may also take a sample of the fluid from the blister and send it to a laboratory for testing.

Treatment

Treatment for herpetic whitlow includes antiviral medications, such as acyclovir, famciclovir, or valacyclovir. These medications can help to reduce the severity and duration of symptoms.

Prevention

Prevention of herpetic whitlow includes avoiding direct contact with herpes sores and using barrier protection, such as gloves, when touching anything that could potentially be contaminated with the virus.
