Accurate assessments of the burden of hand eczema (HE) in the general population are important for public awareness and intervention. The aim of this systematic review and meta‐analysis was to provide updated estimates of prevalence and incidence, alongside additional epidemiological endpoints on HE in the general population. PubMed, Embase and Web of Science were searched for studies reporting the prevalence and/or incidence of HE in the general population. Proportion meta‐analyses were performed to calculate pooled estimates of prevalence, incidence, severity, and the proportion of individuals with HE and a history of atopic dermatitis. Sixty‐six studies were included in the quantitative analysis encompassing 568 100 individuals. The pooled estimates for lifetime, 1‐year, and point prevalence were 14.5% (95% confidence interval [CI]: 12.6–16.5), 9.1% (95% CI: 8.4–9.8) and 4.0% (95% CI: 2.6–5.7), respectively. The pooled incidence rate of HE was 7.3 cases/1000 person‐years (95% CI: 5.4–9.5). The occurrence of HE was 1.5–2 times higher in females than males. More than one third suffered from moderate/severe disease and around one third had a history of atopic dermatitis. HE was a recurrent, long‐lasting disease with an average age at onset of the early‐ to mid‐twenties. In conclusion; HE is a highly prevalent disease in the general population and carries a significant risk of long‐term or chronic disease. [ABSTRACT FROM AUTHOR]

Background: During the first wave of the COVID‐19 pandemic of Spring 2020, Denmark was one of the first countries to introduce lockdown measures, including closing of all daycare centers. Following the reopening of daycare centers, Danish Health Authorities implemented a mandatory intensive hand hygiene regimen. Objectives: To examine the occurrence and point prevalence of hand eczema as a consequence of more intensive hand hygiene among Danish children attending daycare. Methods: The heads of 1667 daycare centers in Denmark were contacted and asked to forward a link to a questionnaire to parents of the children attending the daycare center. Results: Among 6858 children, 12.1% had hand eczema before reopening of daycare centers, whereas 38.3% reported hand eczema after the children returned to daycare. Of the children who never had hand eczema, 28.6% developed hand eczema after returning to daycare. The risk of hand eczema was significantly associated with atopic dermatitis, female gender, higher age, and frequency of handwashing. Conclusion: Following the implemented hygiene regimen, a high proportion of young children rapidly developed hand eczema. Well‐established prophylactic skin care might have spared a proportion of the children from developing hand eczema. [ABSTRACT FROM AUTHOR]
