Activities typically include educational campaigns to disseminate information about the disease's causes, symptoms, and treatments, as well as community events like walks and fundraisers to support those affected. Volunteers often engage with leprosy care centers, providing companionship and assistance to improve the quality of life for patients. Advocacy efforts are also encouraged, highlighting the need for better healthcare services and combating societal stigma. The day serves as a reminder of the importance of understanding and compassion in addressing the health challenges associated with leprosy.
