Mechanism of Injury / Pathological Process[edit | edit source]

Herpetic whitlow is caused by the Herpetic Simplex Virus (HSV). HSV is of two types - type 1 and type 2. They are both known to cause whitlow. Herpetic whitlow is caused when a wounded and exposed skin comes in contact with body fluids contaminated with HSV. It may also be caused by bacterial fingertip infection. [2]

High fever (temperature over 101°F) and confusion/lack of consciousness may indicate serious infection/progression of the disease.

Management / Interventions[edit | edit source]
