to people in Texas, Louisiana and Florida, where humans come into contact with the animals.

Can you get leprosy by touching an armadillo?

In the southern United States, some armadillos are naturally infected with the bacteria that cause Hansen's disease in people and it may be possible that they can spread it to people. However, the risk is very low and most people who come into contact with armadillos are unlikely to get Hansen's disease.

How did armadillos get leprosy?

Exactly how the armadillos became infected by humans is not clear, but one theory is that they picked it up from contaminated soil by digging. Surveys of armadillos in the Gulf states found that up to 20 percent were infected with M. leprae.

Can you get leprosy from eating armadillo?

Wild armadillo meat is popular in Brazil, but a new study shows those who eat it put themselves at risk of contracting leprosy. In Brazil, it's not uncommon to eat armadillo, which reportedly tastes like chicken. But new research warns against the practice—it could give you leprosy.

How do you catch leprosy?

Scientists have learned that to catch leprosy, a healthy person must have months of close contact with someone who has leprosy. It's believed that the disease spreads when a person who has leprosy coughs or sneezes. When a healthy person repeatedly breathes in the infected droplets, this may spread the disease.

How did leprosy get to Hawaii?

It was the global prevalence of leprosy that spread the disease to Hawaii in the 19th century, when many migrated to the island to work the land. As Hawaiians hadn't been previously exposed to the disease, their lack of any protective immunity helped the infection thrive upon its arrival.

Do possums carry leprosy?

The incubation period for the bacteria is at least two years, and possibly five or six, before it is expressed. Being long-lived is a requirement for acquiring leprosy. For example, even if possums were susceptible, their normal life span is only about two years; therefore, they would not have time to get leprosy.

Is it safe to eat an armadillo?

It may seem like an odd question, but the answer is “Yes”. In many areas of Central and South America, armadillo meat is often used as part of an average diet. Armadillo meat is a traditional ingredient in Oaxaca, Mexico.

Can leprosy be cured?

Hansen's disease (also known as leprosy) is an infection caused by slow-growing bacteria called Mycobacterium leprae. It can affect the nerves, skin, eyes, and lining of the nose (nasal mucosa). With early diagnosis and treatment, the disease can be cured.

Are humans immune to leprosy?

Hansen's disease is far less contagious than other infectious diseases. More than 95 percent of the human population has a natural immunity to the disease. Healthcare workers rarely contract Hansen's disease. Most cases of Hansen's disease respond to treatment and become non-infectious within a very short time.

How long does leprosy live outside the body?

M. leprae can survive outside the human body for as long as 46 days. [21] Hence, any bacilli shed from the skin, nose or mouth into the environment, on articles of daily use or on the soil may come in contact with bare skin and result in infection.

Do leper colonies still exist today?

A tiny number of Hansen's disease patients still remain at Kalaupapa, a leprosarium established in 1866 on a remote, but breathtakingly beautiful spit of land on the Hawaiian island of Molokai. Thousands lived and died there in the intervening years, including a later-canonized saint.

Are there still leper colonies in the United States?

In the U.S., leprosy has been all but eradicated, but at least one ostensible leper colony still exists. For more than 150 years, the island of Molokai in Hawaii was home to thousands of leprosy victims who gradually built up their own community and culture.
