Leprology is the study of leprosy, which is a chronic infectious disease that predominantly affects the skin and nerves. However, there are several other synonyms for the word leprology. These include Hansenology, as the disease is often referred to as Hansen's disease after the scientist Gerhard Armauer Hansen, who discovered the bacteria responsible for leprosy. Other synonyms include leprosyology, leprosy study, leprology, and lepromatologist. Despite the different terms used to describe the study of leprosy, the ultimate aim remains the same: to gain a deeper understanding of the disease, its symptoms, transmission, prevention, and treatment.
