Understanding Leprosy: Definition, Causes, and Modern Terminology

Leper refers to a person affected with leprosy, a chronic infectious disease caused by Mycobacterium leprae or Mycobacterium lepromatosis, mainly characterized by severe skin sores, disfigurement, and nerve damage.

The term "leper" has often been used historically, and it can carry negative connotations or stereotypes. Some people affected by leprosy may prefer not to be referred to as lepers and might use terms such as "people affected by leprosy" or "individuals with leprosy" to describe themselves more respectfully and accurately.
