Recent media attention surrounding a leprosy case in central Florida has sparked concerns about the spread of this ancient disease in the United States. But how significant is this single case, and should we be worried about the potential for a leprosy pandemic? Let’s take a closer look at what’s happening and what we need to know.
What is Leprosy?
Leprosy, also known as Hansen’s disease, is a chronic infection caused by Mycobacterium leprae bacteria, closely related to the organism responsible for tuberculosis. This age-old disease affects the skin, nerves, and linings of the eyes and upper respiratory tract. Its presence can be traced back to some of humanity’s earliest writings, including the Old Testament, and has been genetically identified in archaeological remains dating as far back as 2000 BC.
Common symptoms of leprosy include red or thickened patches on the skin, reduced sensation, numbness or weakness in the hands and feet, and nonhealing wounds, blisters, and skin cracks. Left untreated, leprosy may lead to skin deformities, often requiring surgical amputations to manage chronic ulcers or infections.
How Leprosy Outbreaks Occur
Leprosy cases have been reported in the United States for quite some time. In the 1980s, the annual case count exceeded 400, but in recent times, it hovers around 150 cases annually. These numbers can fluctuate, with 216 cases reported in 2019 and 159 in 2020.
Leprosy, while rare in the United States, can spread from person to person, typically requiring prolonged contact with an infected individual. Most cases in the U.S. involve people who have either traveled to regions with higher leprosy prevalence or have had direct contact with nine-banded armadillos, animals known to carry the disease.
The exact reason for leprosy’s persistence in central Florida remains uncertain. While person-to-person transmission usually necessitates prolonged, close contact, around 75% of new leprosy cases in Florida lack identifiable sources. This mystery prompts speculation about potential environmental sources or other unidentified carriers, aside from armadillos.

Leprosy Outbreak in Central Florida
Central Florida is currently grappling with a leprosy outbreak, as reported by the Centers for Disease Control and Prevention (CDC). This region now accounts for nearly one-fifth of all leprosy cases detected in the United States, signaling a shift in the disease’s prevalence.
Historically, Florida was not recognized as a hotspot for leprosy. However, recent data suggests that the illness has become endemic within the state. An endemic disease is one that consistently exists within a specific region. It is essential to note that the CDC has not issued a travel warning for Florida, indicating that visiting the area does not imply contamination.
Is Leprosy Common in Florida?
The single case of leprosy in central Florida detected in August was notable because the diagnosed individual had no apparent risk factors for the disease. He had not traveled to areas where leprosy is common, nor had he come into contact with infected individuals.
While the number of leprosy cases in Florida has seen an increase, with about 20 cases annually since 2015, it is important to clarify that leprosy is not common in the state. Central Florida, where approximately 80% of Florida’s cases are diagnosed, may be showing signs of endemic leprosy. Endemic means that there are enough sources of infection within a particular area to sustain the disease’s presence, even without new cases introduced from elsewhere.
Experts acknowledge the emerging endemic trend but stress that this does not warrant a public health crisis. Central Florida’s situation is still characterized by relatively low case numbers. Therefore, there is no need for excessive concern.
Leprosy in the U.S.: A Rarity
It’s crucial to emphasize that for the majority of people in the United States, leprosy remains an uncommon concern. Despite a recent increase in cases, approximately 180 leprosy cases are diagnosed annually. This figure marks a slight uptick from fewer than 100 cases recorded in 1999 and 2000, highlighting the disease’s rarity in the U.S.
In contrast, the global perspective reveals a different reality. According to the World Health Organization, over 200,000 leprosy cases are diagnosed annually across 120 countries. The highest incidence occurs in Brazil, India, and Indonesia.
Dispelling Myths About Leprosy
Misconceptions about leprosy can fuel stigma and discrimination against those affected. Here are some common myths about the disease:
I. Myth: Leprosy is highly contagious.
Fact: Leprosy is not as contagious as many other infections. It requires prolonged and close contact to spread. Most people are naturally immune to leprosy, and within one week of treatment, an infected person is no longer contagious.
II. Myth: Leprosy causes body parts to fall off.
Fact: Body parts do not spontaneously fall off due to leprosy. Surgical amputations may be necessary to treat complications resulting from longstanding nerve damage related to the disease.
III. Myth: Leprosy has no treatment.
Fact: Leprosy is treatable with antibiotics, typically involving a combination of two or three drugs taken simultaneously. Early diagnosis and treatment are crucial to prevent complications.
Seeking Medical Care for Leprosy
If you develop symptoms suggestive of leprosy, it is vital to consult a healthcare professional promptly. Leprosy can be challenging to diagnose, particularly in its early stages, but characteristic signs include a lack of sensation in affected skin patches or unusual sensations over them.
Diagnosis typically involves a skin biopsy, and treatment usually consists of a combination of antibiotics taken for a year or more. Timely medical attention is essential, as untreated leprosy can lead to serious complications such as paralysis, blindness, and deformities.
While leprosy remains an unusual diagnosis in the United States, healthcare providers are trained to identify and report cases promptly, initiating the necessary treatment and contact-tracing procedures. Awareness and accurate information can help dispel fears and misconceptions surrounding this age-old disease.
Q : Is leprosy highly contagious?
A : No, leprosy is not highly contagious and requires prolonged, close contact for transmission.
Q : Can leprosy cause body parts to fall off?
A : No, leprosy does not cause body parts to spontaneously fall off. Surgical amputations may be necessary for complications resulting from nerve damage.
Q : Is leprosy common in the United States?
A : No, leprosy is rare in the United States, with approximately 180 cases diagnosed annually.
