Introduction
Skin diseases are a global health priority, affecting billions and often signalling serious systemic illnesses. Dermatologists are uniquely positioned to advance early diagnosis and treatment, reducing disability and stigma worldwide. This article explores how dermatologists contribute to global health through advocacy, research, and frontline support, highlighting key neglected tropical diseases and innovative WHO initiatives aimed at empowering healthcare workers globally.
Dermatologists at the Forefront of Global Health
Advocacy and Policy Influence
Dermatologists have become key advocates in global health, pushing for greater recognition of skin diseases as a significant public health issue. Through national and international policy efforts, they have successfully influenced the inclusion of more dermatologic therapies in the World Health Organisation’s Model List of Essential Medicines, which ensures wider access to effective treatments worldwide.
In the UK, dermatologists contribute expert guidance to bodies such as NICE, shaping NHS treatment pathways and funding decisions for skin conditions, ensuring evidence-based and equitable care. Internationally, dermatologists advise organisations like the WHO on guidelines for neglected tropical diseases (NTDs), including leprosy and vitiligo, helping to align global policies with the complex realities of skin disease.
Moreover, dermatologists have championed the cause of equality and inclusion by advocating for better representation of diverse skin tones in medical education and diagnostic tools. This work addresses disparities in diagnosis and treatment, such as the delayed recognition of melanoma in darker-skinned individuals, which can lead to poorer outcomes.
Research Contributions and Disease Burden Characterisation
Dermatologists have led efforts to quantify the global burden of skin disease, which ranks as the fourth leading cause of nonfatal disease burden worldwide in terms of disability-adjusted life years (DALYs). They have contributed to large-scale epidemiological studies such as the Global Burden of Disease project, which highlights geographic and demographic variations in skin disease prevalence and impact.
For example, dermatitis causes the greatest burden globally, while infectious skin diseases like scabies disproportionately affect children in resource-poor regions.
This research has been critical in informing global health priorities and resource allocation. Dermatologists also actively participate in pandemic research, exemplified by their role in establishing a worldwide registry for cutaneous manifestations of COVID-19, which has enhanced understanding of the disease’s systemic effects.
Early Diagnosis: A Critical Tool Against Disability and Stigma
Neglected Tropical Diseases with Skin Manifestations
Many neglected tropical diseases (NTDs) present with skin symptoms, making dermatological expertise essential for early detection and management. Skin involvement is often the first and most visible sign of diseases such as leprosy,
Buruli ulcer and scabies, which predominantly affect populations in resource-limited settings. Early diagnosis can prevent severe disability, reduce transmission, and combat the social stigma associated with these conditions.
Due to the lack of reliable laboratory tests for many NTDs, clinical examination remains the cornerstone of diagnosis. However, the shortage of trained dermatologists in endemic areas poses a major challenge. Training frontline health workers to recognise key skin changes is therefore a vital strategy to improve early case detection and treatment outcomes.
WHO Initiatives Empowering Frontline Health Workers
The Pictorial Training Guide for Skin NTDs
To address the diagnostic gap in resource-poor settings, the World Health Organisation has developed a pictorial training guide titled “Recognising neglected tropical diseases through changes on the skin”. This guide simplifies diagnosis by focusing on four major skin changes—lumps, ulcers, swollen limbs, and patches—and provides flowcharts to help frontline health workers identify likely conditions and decide on treatment or referral.
The guide has proven effective in improving diagnostic accuracy and referral appropriateness, as demonstrated in training programs in Mali and other endemic regions. It also supports the involvement of traditional healers, who often serve as first points of contact in rural communities, in early case detection.
Digital Tools and Apps for Rapid Diagnosis
Building on the pictorial guide, digital tools such as the WHO Skin NTD app have been developed to further empower healthcare workers. These smartphone applications offer user-friendly, secure platforms for syndrome-based assessment, helping non-specialists navigate complex differential diagnoses.
While promising, these digital tools require further validation for diagnostic accuracy and training impact. Nevertheless, the widespread adoption of mobile technology in Africa and other regions presents a unique opportunity to enhance skin NTD diagnosis and management through teledermatology, artificial intelligence, and mobile health innovations.
Addressing Global Dermatological Deserts
The Crisis of Limited Access to Dermatologists
A significant global health challenge is the scarcity of dermatologists in many regions, creating what are termed “dermatological deserts.” Over a third of countries have one dermatologist or fewer per 100,000 people, leaving at least 3.5 billion individuals without adequate access to specialised skin care. This shortage is particularly acute in underserved populations, rural areas, and low-income communities, where socioeconomic factors and geographic barriers further limit access.
The consequences include delayed diagnosis of serious conditions such as melanoma and non-melanoma skin cancers, leading to worse outcomes and increased disability. The rising incidence of skin diseases, combined with an ageing population and increased demand for dermatology visits, exacerbates this crisis. Addressing these deserts is essential to reduce preventable morbidity and mortality associated with skin diseases globally.
Training and Capacity Building for Frontline Providers
To mitigate the shortage of dermatologists, training and capacity building of frontline healthcare providers—including nurses, physician assistants, and community health workers—have become critical strategies. Specialised dermatology training programs, such as the “Advanced Training in Dermatology” for nurses and PAs, offer comprehensive education on skin condition identification, management, and patient counselling.
In the context of neglected tropical diseases, initiatives like the PEP4LEP program provide interactive, refresher training modules to improve health workers’ ability to diagnose leprosy and other skin diseases accurately. Digital tools and teledermatology platforms further empower non-specialists to triage and manage skin conditions effectively, facilitating earlier referrals and treatment. Collaborative efforts between governments, NGOs, and dermatology societies aim to scale these training programs to bridge the gap in dermatological care.
The Future of Dermatology in Global Health
Integrating Skin Health into Universal Health Coverage
The integration of skin health services into universal health coverage (UHC) frameworks is vital for ensuring equitable access to dermatological care worldwide. Recognising skin diseases as a public health priority, global health bodies advocate for the inclusion of essential dermatologic treatments and diagnostics in primary healthcare packages. This approach supports early detection, reduces the burden of chronic and infectious skin diseases, and aligns with broader goals of health equity. Dermatologists play a key role in shaping policies that embed skin health within national health systems, facilitating sustainable funding and resource allocation. The expansion of teledermatology and AI-driven diagnostic tools also supports scalable, cost-effective delivery of dermatology services within UHC models.
Multidisciplinary Approaches and Holistic Care
The future of dermatology embraces multidisciplinary collaboration and holistic patient care. Advances in therapeutics, such as biologics for chronic inflammatory diseases, demonstrate the systemic benefits of effective skin disease management beyond the skin itself. Dermatologists increasingly work alongside immunologists, primary care providers, mental health professionals, and community health workers to address the complex physical, psychological, and social impacts of skin diseases.
Innovations in artificial intelligence and quantum medicine are transforming diagnostics and treatment, enabling personalised and precise care. Emphasising equity, diversity, and inclusion, dermatology is evolving to meet the needs of diverse populations globally, ensuring that advances benefit all skin types and communities. This holistic, patient-centred approach is essential to improving outcomes and quality of life for individuals affected by skin diseases worldwide.
