Hand Dermatitis in the Time of COVID-19: A Review of Occupational Irritant Contact Dermatitis.

Occupational contact dermatitis accounts for 95% of all cases of occupational skin disease with irritant contact dermatitis (ICD) constituting 80% to 90% of these cases. Health care workers, hairdressers, and food service workers are typically most affected by occupational ICD of the hands as these occupations require frequent hand hygiene and/or prolonged exposure to water, also known as "wet work." In the context of the current COVID-19 pandemic, frequent hand hygiene has become a global recommendation for all individuals, and new workplace guidelines for hand sanitization and surface sterilization are affecting occupations not previously considered at risk of excessive wet work including grocery or retail workers, postal workers, sanitization workers, and others. In this review, we discuss the etiology and pathogenesis of occupational ICD with additional focus on treatment and interventions that can be made at an institutional and even national level for education and prevention of ICD resulting from frequent hand hygiene.
