Herpes simplex virus infection of the hand. A profile of 79 cases

Seventy-nine cases of herpes simplex (HSV) infection of the hand were documented by viral culture over a 40-month period. A marked bimodal age distribution was found with 32 cases occurring in adults aged 21 to 30 years and 16 occurring in children less than 10 years old. The infection most commonly occurred on the fingers (69 percent) and thumb (21 percent). All 20 herpes simplex type 2 (HSV-2) isolates came from patients over 20 years old. All of the 13 specimens that were typed after isolation from patients under 20 years old were herpes simplex type 1 (HSV-1). Only seven of the 49 adult cases were identified in health care professionals. In this series, HSV infection of the hand occurred in 2.4 cases per 100,000 population per year. In adults, women with recurrent infections from HSV-2 and a history compatible with genital herpes predominated. In children, a primary HSV-1 infection associated with gingivostomatitis was common.
