The Ridley-Jopling system has six classifications based on the severity of symptoms.


**Intermediate leprosy**: a few flat lesions that sometimes heal by themselves and can progress to a more severe type

**Tuberculoid leprosy**: a few flat lesions, some large and numb; some nerve involvement; can heal on its own, persist, or may progress to a more severe type.

**Borderline tuberculoid leprosy**: lesions similar to tuberculoid but smaller and more numerous; less nerve enlargement; may persist, revert to tuberculoid, or advance to another type

**Mid-borderline leprosy**: reddish plaques, moderate numbness, swollen lymph glands; may regress, persist, or progress to another type


**Borderline lepromatous leprosy**: many lesions including flat lesions, raised bumps, plaques, and nodules, sometimes numb; may persist, regress, or progress to another type

**Lepromatous leprosy**: many lesions with bacteria; hair loss; nerve involvement; limb weakness; disfigurement; doesn’t regress<|im_end|>

Leprosy is a long term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis.

can you in details describe every type of this disease?<|im_end|>

Sure, I'd be happy to provide a more detailed description of the six types of leprosy.

- **Tuberculoid leprosy:** This is the mildest form of leprosy. People with this type of leprosy typically have a few patches of flat, pale or reddish skin with a loss of sensation. The patches may be numb to touch, heat, or cold. There may also be nerve damage, leading to muscle weakness or paralysis.

- **Borderline tuberculoid leprosy:** This type of leprosy is a bit more severe than tuberculoid leprosy. It is characterized by more numerous skin lesions and greater nerve damage, leading to muscle weakness or paralysis.

- **Mid-borderline leprosy:** This is an intermediate form of leprosy that has symptoms of both borderline tuberculoid and borderline lepromatous leprosy.

- **Borderline leprosy:** This is another intermediate form of leprosy. People with this type of leprosy may have more widespread skin lesions and more nerve damage than those with borderline tuberculoid leprosy, but less than those with lepromatous leprosy.

- **Lepromatous leprosy:** This is the most severe form of leprosy. People with this type of leprosy may have widespread skin lesions, thickened skin, and nodules on the skin. They may also experience severe nerve damage, leading to muscle weakness or paralysis. People with lepromatous leprosy may also experience vision problems, as well as damage to the kidneys, testes, and other organs.

- **Intermediate leprosy:** This type of leprosy falls between tuberculoid and lepromatous leprosy. People with intermediate leprosy may have symptoms of both types of leprosy, with patches of skin lesions and nerve damage that is less severe than that seen in lepromatous leprosy.

I hope this information is helpful. If you have any further questions, feel free to ask.<|im_end|>
