[Three cases of occupationally induced herpetic whitlow in health care workers]

Herpetic whitlow is one of the herpes simplex virus (HSV) infections, and is known as an occupational disease. In Japan, however, there have been only a few reports of this disease. Recently, we experienced three cases of herpetic whitlow in health care workers. They presented painful vesicles on the right ring finger, the left thumb and the left index finger, respectively. All of them were considered to have been infected by HSV when they were engaged in mouth care of inpatients. We reviewed these three cases from the aspect of occupational medicine, and propose the following three points for preventing this serious nosocominal infection to health care workers: 1) re-education and enlightenment for the workers regarding hazardous behavior of HSV, 2) keeping the hands and fingers free from skin impairments, and 3) early diagnosis and treatment for herpetic whitlow of health care professionals to prevent further nosocominal infection.
