World Leprosy Day is observed worldwide on the last Sunday of January, with the next occurrence on January 25, 2026. This annual awareness day aims to educate the public about Hansen's disease, commonly known as leprosy, which is caused by two types of Mycobacteria. The day was first observed in 1954 and commemorates the death anniversary of Mahatma Gandhi, who significantly contributed to raising awareness about the disease. Leprosy, one of the oldest diseases mentioned in the Bible, affects the nervous system, respiratory tract, skin, and eyes, and is primarily found among impoverished populations. Despite its historical stigma and discrimination faced by those affected, leprosy is curable with proper treatment if diagnosed early. The observance encourages efforts to combat discrimination and improve access to treatment for individuals suffering from the disease.
