Hansen's Disease, also known as leprosy, is a chronic infectious disease caused by the bacterium Mycobacterium leprae. It primarily affects the skin, nerves, and mucous membranes, leading to skin lesions and nerve damage. The disease is transmitted through respiratory droplets, but it is not highly contagious. Symptoms of Hansen's Disease can take years to appear and may include numbness, muscle weakness, and discolored patches on the skin. Early diagnosis and treatment with antibiotics can effectively manage the disease and prevent complications. With proper care, individuals can lead healthy lives and reduce the risk of transmission.
