AI-Powered Dermatology for Dark Skin Tones: New Database Aims to Bridge Healthcare Gap in Africa

Addressing the Dermatological Crisis in Africa

In many African countries, a severe shortage of dermatologists has left millions, particularly children, suffering from untreated skin conditions. With less than one specialist per million people in some areas, compared to the World Health Organization's recommendation of one per 50,000, the need for innovative solutions is critical 1

The PASSION Project: AI-Powered Dermatology

To address this healthcare gap, researchers from the University of Basel, led by Professor Alexander Navarini, have launched the PASSION project (Pediatric AI Skin Support In Outreach Nations). This initiative aims to leverage artificial intelligence (AI) to support dermatological diagnostics in regions with limited access to specialists 1

Creating a Diverse Image Database

A key challenge in developing AI for dermatological diagnosis is the lack of diverse training data. Existing databases primarily contain images of light skin types from European and U.S. clinics. To overcome this, the PASSION team has created a new database focusing on common skin diseases in darker skin tones 1

The database includes:

• Over 4,200 images from around 1,300 patients
• Two-thirds of patients under 18 years old
• Images of eczema, fungal infections, scabies, and bacterial skin infections
• Data collected from Madagascar, Malawi, and Guinea between 2020 and 2023

AI-Powered Self-Diagnosis Vision

The researchers envision a future where patients can use smartphones to photograph their skin conditions and receive AI-generated treatment recommendations. This approach could revolutionize triage and initial treatment in underserved areas 1

Philippe Gottfrois, lead author of the study, states, "We are currently testing the method step by step as part of a validation study in Madagascar. Once diagnostic accuracy exceeds 80%, we intend to offer the new diagnostic tool with scientific monitoring" 1
