Hansen's disease, also known as leprosy, is a chronic infection caused by the bacterium Mycobacterium leprae. It primarily affects the skin, nerves, and mucous membranes, leading to symptoms like skin lesions, numbness, and muscle weakness. The disease is not highly contagious and is usually spread through prolonged close contact with an infected person. With early diagnosis and treatment, Hansen's disease can be effectively managed. The standard treatment involves a combination of antibiotics, which can help prevent complications and transmission. Awareness and education about the disease are crucial to reduce stigma and support those affected by it.
