Herpetic whitlow: an occupational disease of practicing dentists.

Recurrent herpes simplex virus lesions of fingers, hand, or eyes are suspected to be encountered in health practitioners in greater frequency than in the general population. To determine whether an increased risk of disease contraction coincident to practicing dentistry exists and to determine the magnitude of risk, a survey of dentists practicing in the state of Michigan was conducted. An age and sex matched nondentist patient from each respondent's practice provided a control population. Frequency of herpes labialis and herpes infection of the eye were found be lower in dentists than in the control population. Conversely, herpetic whitlow was found to be more frequent in practicing dentists than in the control population. If the occurrence of herpes labialis in each of the two groups is taken as the reference point, the frequency of herpetic whitlow is significantly higher among practicing dentists than among the control population (P less than .01).
