An infection of the finger and especially the fingertip that is typically caused by infection of a virus (as the herpes simplex virus) and is marked by redness, tenderness, and fluid-filled blisters.
Symptoms of herpetic whitlow include swelling, reddening and tenderness of the skin of infected finger. This may be accompanied by fever and swollen lymph nodes. Small, clear vesicles initially form individually, then merge and become cloudy. Associated pain often seems large relative to the physical symptoms.
Occasionally infection occurs on the toes or on the nail cuticle. Herpes whitlow can be caused by infection by hsv-1 or hsv-2.
