Herpetic whitlow: an occupational hazard.
Herpetic whitlow is a herpes infection of the digits of the hand, first described in 1909, caused by either herpes simplex virus type 1 or type 2. It was not until 1959 that herpetic whitlow was reported to occur in health care professionals. Nurse anesthetists are among the many health care professionals considered to be at high risk for acquiring herpetic whitlow, making it an occupational, but preventable, disease. After an initial infection, the virus invades the nerve tissue supplying the affected area, thus creating a reservoir for the virus to remain latent until reactivated. The recurrence of herpetic whitlow suggests that the infection persists for life. Pain, tingling and burning of the distal phalanx are the initial symptoms. Swelling and vesicles on an erythematous base follow. The infection is self-limiting, usually resolving in about three weeks. Primary infections are very inflammatory and persistent. Diagnosis can be made clinically and confirmed by many laboratory tests. Early recognition is most important, and treatment is symptomatic. The drug acyclovir has proven to be an effective chemotherapeutic agent for suppressive therapy.
