Leprosy

Leprosy is a chronic infectious disease caused by the bacterium Mycobacterium leprae. It primarily affects the skin, nerves, and mucous membranes, leading to disfigurement, nerve damage, and progressive disability if left untreated. The disease often begins with discolored patches of skin that may be numb to the touch, as the bacteria target and damage the peripheral nerves. As the infection progresses, it can cause severe nerve degeneration, leading to muscle weakness, paralysis, and the loss of sensation in the affected areas. Without sensation, injuries can go unnoticed, resulting in further tissue damage and, in severe cases, the loss of fingers, toes, or limbs. Leprosy is not highly contagious and spreads through prolonged close contact with an infected person, typically via respiratory droplets.
