Hansen’s disease is typically used in a medical context. Though the word leprosy is much more well known, it has a history of stigmatization, so the name Hansen’s disease is often preferred.

Today is the 114th anniversary of the arrival of the 1st 365 Hansen's Disease patients in Culion, commencing the segregated leper colony project of the American administration in the #PH. Thru Act No. 1711, patients were required to relocate to the island.#MakeItHistoric pic.twitter.com/hfOgMd6Abc

Hansen's disease patients really prefer to be called Hansen's disease patients now.
"Leper" has really awful connotations.

#HiddenNoMore Alice Ball, Pharmaceutical Chemist

Ball, a chemistry instructor at the College of Hawaii, improved a key treatment for leprosy (Hansen’s Disease). The "Ball Method" was used for decades. In 1916, a year after her discovery, Ball died. She was just 24 years old. pic.twitter.com/7ivP0Nembc
