Florida’s latest Hansen’s disease cases are medically manageable, but the older name for the same infection, leprosy, is much harder to contain because it carries centuries of biblical imagery.
Although referring to the same chronic bacterial infection, the terms leprosy and Hansen’s disease do different cultural work. The latter sounds like a diagnosis while the former summons biblical punishment, ritual impurity, exile and the figure of the outcast. Some coverage of Florida’s 2026 cases has reinforced those associations by calling it a “biblical disease.”
The irony is that the conditions translated as “leprosy” in many English Bibles were probably not Hansen’s disease at all. Florida’s outbreak is therefore exposing two separate problems: a rare infection that modern medicine can treat and an ancient vocabulary that still teaches people to fear the infected.

Florida’s Cases Are Real, Rare and Treatable
Florida had recorded 17 cases by late July, mostly in central counties. A 2023 CDC report said the region may have become endemic for Hansen’s disease after documenting locally acquired cases with no travel history or known exposure.
Nine-banded armadillos can carry the bacteria, though exposure does not guarantee infection. Person-to-person transmission usually requires prolonged close contact with someone who has untreated disease.
The illness can cause permanent nerve damage if diagnosis is delayed, but early treatment cures it. The public-health task is therefore straightforward: help doctors recognize the symptoms, track local transmission and encourage patients to seek care.
The problem is the conversations surrounding the issue, which refer to it as a biblical disease, a term that turns a limited medical problem into a story about fear.

How a Translation Error Became a Medical Stigma
The biblical condition later translated into English as “leprosy” was not the bacterial infection now called Hansen’s disease. Biblical descriptions grouped together changes affecting human skin, clothing and even buildings, symptoms that cannot belong to one modern diagnosis. Scholars therefore regard biblical “leprosy” as a broad category of ritual impurity rather than Hansen’s disease.
The translation nevertheless attached the biblical label to the modern infection, so patients then inherited the label’s social meaning: the “leper” as unclean, threatening and unfit to remain within the community. A historical error in naming helped turn a treatable disease into an identity.
Public policy reinforced the association. Fear of contagion once led the United States to confine patients at the federal leprosarium in Carville, Louisiana, even though Hansen’s disease is difficult to transmit. Advocates later promoted “Hansen’s disease” to reduce the stigma and honor Gerhard Armauer Hansen, who identified its bacterium.
The new name clarified the science, but it did not erase the older image.
Why 'Biblical Disease' Still Sells
“Biblical disease” works as a headline because it compresses centuries of fear into two familiar words. It promises something ancient, mysterious and newly returned, giving a small cluster of cases the emotional scale of a plague.
There is a defensible reason to use the word “leprosy.” It remains more recognizable than Hansen’s disease, and public-health agencies often use both terms together so patients and doctors understand they describe the same infection. Familiar language can encourage people with possible symptoms to seek medical advice.
The problem begins when recognition gives way to spectacle. “Biblical” does not simply mean old. It carries associations with punishment, impurity and exclusion, encouraging readers to interpret infection as evidence of moral or social disorder. The phrase can therefore make the disease appear more contagious and less curable than it is.
That distortion has consequences.
The CDC says Hansen’s disease is difficult to catch and completely curable, yet stigma and prejudice continue to isolate people with the illness.
The World Health Organization treats ending discrimination as part of controlling the disease, because shame can discourage disclosure and delay treatment.
The biblical frame sells because it makes the story feel larger and more dramatic, which is exactly what America craves these days.
