On World Leprosy Day, we remember a disease that has affected humanity for thousands of years. Leprosy, also known as Hansen's disease, is caused by the bacteria Mycobacterium leprae, discovered by the Norwegian physician Gerhard Armauer Hansen in 1873, or Mycobacterium lepromatosis. This chronic infection primarily affects the skin, nerves, and mucous membranes, leading to severe disfigurement and disabilities if left untreated. Historically, leprosy was associated with social stigma and isolation. Leprosy is prevalent in tropical and subtropical regions, with the highest incidence in Africa, Asia, and Latin America. It's estimated that about 200,000 new cases are reported annually worldwide. Transmission occurs through close and frequent contact with untreated cases. It is curable with multidrug therapy, a combination of antibiotics, available since the 1980s. This treatment has transformed the prognosis of the disease, enabling full recovery if diagnosed early. No vaccine exists yet. World Leprosy Day, observed on the last Sunday of January, is a time to spread awareness about the disease, challenge misconceptions, and support those affected. It reminds us of the need for continued efforts in research, treatment, and eliminating the stigma associated with it.
