Epidemiology
Epidemiologic data on dyshidrotic dermatitis as a single condition (i.e., not under the wider umbrella of hand dermatitis) is lacking.[1] A large Swedish study found the prevalence of dyshidrotic dermatitis in a general population of 107,206 people to be 0.05%.[3] Another study in Portugal reported that, of 714 subjects with hand dermatitis, 20% had dyshidrotic dermatitis.[4] An analysis of insurance claims for dyshidrotic eczema from 27 million people in the US with private healthcare coverage revealed 34,932 patients were diagnosed in 2018 with 214,974 visits in that year. The average age was 37.1 years and most patients (61.0%) were female.[5]
