Lepra has been working to tackle the human and systemic consequences of leprosy for the past 100 years. Despite the disease being curable, leprosy continues to cause disabilities and social isolation, and affects millions of lives annually, particularly in the world's poorest areas. Recent figures from the World Health Organisation show more than 170,000 new leprosy cases were reported globally in 2024. However, most people living with leprosy are never formally diagnosed, and the true figure is likely four to five times higher. The disease often goes undetected due to social stigma, fragile health systems, and a lack of trained personnel, with millions potentially living with undiagnosed leprosy.
