Mycobacterium leprae is the bacterium responsible for causing leprosy, also known as Hansen's disease. It is an acid-fast, slow-growing bacterium that primarily affects the skin, peripheral nerves, and mucous membranes. Leprosy is a chronic infectious disease that can lead to significant disabilities if left untreated.

Mycobacterium leprae has a unique ability to evade the human immune system, making it challenging to eradicate. It is transmitted through prolonged close contact with an infected person, but not everyone who comes into contact with the bacteria develops the disease. The incubation period can range from months to years.

The bacterium primarily affects the cooler parts of the body, such as the skin, nerves, and upper respiratory tract. The clinical manifestations of leprosy can vary widely, ranging from mild skin lesions to severe deformities and nerve damage. Early diagnosis and multi-drug therapy are crucial for effective treatment and prevention of disabilities.

Despite significant progress in the control of leprosy worldwide, pockets of the disease still exist, particularly in poverty-stricken regions with limited access to healthcare. Ongoing research aims to develop better diagnostic tools, more effective treatments, and strategies for global elimination of leprosy as a public health problem.
