Whitlow
Whitlow or Herpetic whitlow is a viral infection of the finger or toe caused by the herpes simplex virus (HSV). It is a painful condition that typically affects the fingers or thumbs. Occasionally infection occurs on the toe. Other names for it include digital herpes simplex and fingertip herpes.
Causes[edit | edit source]
Whitlow is caused by the herpes simplex virus. There are two types of this virus: HSV-1 and HSV-2. Both types can cause herpetic whitlow. The virus enters the body through broken skin, typically a small cut or abrasion, and travels down the nerve, causing a painful lesion or "cold sore".
Symptoms[edit | edit source]
The symptoms of whitlow include swelling, redness, and pain. A clear or yellowish fluid may be present. The affected area may be sensitive to touch and warm to the touch. The symptoms usually appear one to two weeks after exposure to the virus.
Treatment[edit | edit source]
Treatment for whitlow includes antiviral medication, such as acyclovir, to reduce the severity and duration of the symptoms. Pain relief can also be provided with over-the-counter medication. In severe cases, a surgical procedure may be necessary to drain the fluid from the lesion.
Prevention[edit | edit source]
Prevention of whitlow includes avoiding direct contact with cold sores and using barrier protection, such as gloves, when in contact with others' body fluids. Good hand hygiene can also help prevent the spread of the virus.
