Herpetic whitlow occurs in infants and children who suck their fingers and transfer the virus when they have cold sores (autoinoculation). Healthcare workers, especially dentists, nurses, and other doctors are more at risk of contracting the herpetic whitlow as an occupational hazard from the patients. Herpetic whitlow is also an occupational hazard of beauty therapists and masseurs.
Herpes simplex virus (HSV) is of two types: HSV 1 and HSV 2. HSV 1 usually causes herpes infections in and around the mouth, nose and face, while HSV 2 causes what is known as herpes genitalis on the genitals and the a**l area and buttocks. Both viruses can rarely cause infections in other areas as well. In children and health workers herpetic whitlow is caused by HSV 1 while in other adult populations, it is caused by HSV 2. The ratio of HSV 1 to 2 is calculated to be 60:40 in the causation of herpetic whitlow.

Most commonly affected fingers are the thumb and index finger, for obvious reasons. If it is the first attack, fever and body pain may be experienced 2 days prior to the appearance of the rash. The rash starts as redness, swelling and appearance of grouped, fluid filled small blisters (called vesicles) over 5-7 days. The vesicles are extremely painful and the pain may shoot up the arm. Most patients will also have lymph node swelling above the elbows or the armpits. Over another week, the vesicles dry up, form crusts and heal by themselves. Triggering events like exposure to sun, heat, extreme cold, stress, irritants etc may produce recurrences.
