CMCT has adopted three leprosy colonies in the district of Chengalpet. The programs focus on the holistic rehabilitation of leprosy survivors and their families, many of whom have been isolated due to stigma. The end goal is to help them integrate into mainstream society.

Medical staff and social workers visit the colonies regularly, providing physiotherapy and counselling. A number of income-generating activities and skills have been introduced to encourage survivors to support themselves. Children are provided with skills training and educational assistance. As an additional support, vulnerable families are provided with monthly rations and those suffering extreme deformities are given daily nutritious meals.
