Two patients had herpes simplex infection of the fingertips (herpetic whitlow) associated with herpetic keratitis. Both patients were health-care professionals who probably acquired their disease from patients. Herpetic whitlow can be distinguished from a paronychia by the lack of a tense pulp space, formation of vesicles, and serous (rather than purulent) drainage. The fingertip inflammation resolves spontaneously, leaving normal healthy skin, in about two weeks.
