Epidemiology Atlas
Vitiligo affects approximately 1–2% of the global population. However, the actual prevalence may be significantly higher due to underreporting and misdiagnosis, particularly in regions where access to dermatological care and diagnostic resources is limited. This disparity underscores the urgent need for a unified approach to collecting, analysing and sharing global data on vitiligo.
Who Does Vitiligo Affect?
Research has shown that vitiligo occurs equally in both sexes and can develop at any age. However, nearly 50% of cases emerge before the age of 20, often during formative years when the social and psychological impacts of the condition may be particularly profound. Despite its widespread prevalence, awareness and understanding of vitiligo vary dramatically across regions and cultures, creating additional challenges for those affected.
Where Do We Lack Data?
While substantial data has been collected in countries such as the United States, the United Kingdom, South-eastern Asia and parts of Europe, critical gaps remain in our understanding of vitiligo prevalence. Africa, South America and rural areas of Asia, for example, are significantly underrepresented in global studies. Limited healthcare infrastructure, cultural stigmas and a lack of dermatological services contribute to the scarcity of reliable data.
A lack of comprehensive global data hampers efforts to understand the true scope of vitiligo and its impact on individuals and communities. Without an accurate epidemiological picture, disparities in access to care and treatment options persist, leaving many individuals without adequate support or resources to manage their condition.
The Global Vitiligo Atlas (GLOVA) seeks to bridge these knowledge gaps by creating the first comprehensive, standardised and accessible resource for vitiligo epidemiology. By gathering and analysing data from across the globe, GLOVA aims to illuminate the true prevalence of vitiligo, identify disparities in care, and provide researchers, clinicians, and policymakers with the tools they need to improve outcomes for individuals living with vitiligo worldwide.
With its mission to unify global vitiligo data, GLOVA offers a vital step toward understanding and addressing the global challenges posed by this condition. By creating a clearer picture of vitiligo impact, we can work together to advance treatment options, reduce stigma and improve the quality of life for millions of individuals affected by vitiligo across the world.
