About Us

The Leprosy Mission (TLM) is an international Christian organisation which helps people affected by leprosy. Founded in 1874, The Leprosy Mission is the oldest and largest leprosy-focused organisation in the world today.


Leprosy affects people’s lives in many different ways, so we care for their physical, social, spiritual and psychological needs. In our projects we concentrate on healthcare, community-based rehabilitation, prevention of disability, advocacy, capacity building, education, stigma reduction and occasionally on disaster response and preparedness. Leprosy is not understood by most communities and as a result people are fearful of it, which means those affected by leprosy are often stigmatised.

We want to see a leprosy-free world. Our vision is for ‘leprosy defeated, lives transformed’. This is why our main focus is on leprosy, however, our work often includes other people with disabilities, other neglected tropical diseases, other marginalised people in society, and those living in extreme poverty.

Around the world we have about 2,000 staff and implement or support projects in 18 countries. The largest number of projects is in India, but there are also a significant number in Bangladesh, Myanmar, Nigeria and Nepal. Increasingly the Mission seeks to work with partners as well as implementing projects directly. The gross annual income of the Mission is around £23 million, of which 65% comes through private donations and bequests, 15% comes from government and institutional funders, and 20% from fees and other sources.

Our History

Almost 150 years ago, one man’s spirit of adventure took him to India. There, the future course of his life was set in motion. He saw the appalling living conditions and the social isolation of people with leprosy. His compassion and action birthed The Leprosy Mission, an organisation that now works to bring healing, inclusion and dignity to leprosy-affected people around the world.
