When people began to say that Armadillos carry leprosy, no one thought to outright question the myth.\u00a0 At the time that the idea first started, it was commonly known that many animals carried diseases that were transmitted to humans.\u00a0 It seemed that leprosy was just another to add to this list.\u00a0 But is it true that Armadillos carry leprosy and if so, can they infect humans?<\/p>\n
It’s been know for a few years that Armadillos were carriers of leprosy.\u00a0 According to scientists, they are the only animal other than humans that can host the bacteria that causes leprosy.\u00a0 It’s important to talk about exactly why because it does tell us a bit about the bacteria and the likelihood of it’s transmission. It’s believed, although not proven, that Armadillos carry leprosy because of their body temperature.\u00a0 While it isn’t extremely close to that of humans, it is stable and steady.\u00a0 Unlike other animals who’s body temperatures fluctuate, these armored creature have a pretty good handle on keeping their body temperature the same. Since the bacteria that causes leprosy is a very fragile bacteria, they need a stable temperature.\u00a0 Scientists have hypothesized that this is what enables Armadillos to carry leprosy.<\/p>\n
Do all Armadillos carry leprosy?<\/strong><\/p>\n No.\u00a0 There are several types of Armadillos and it has not been concluded that all types of Armadillos carry leprosy. Instead, it was discovered that the 9 banded Armadillos carry leprosy.\u00a0 At that time it was believed that Armadillos were unlikely to spread the bacteria to humans, mostly in the American South.\u00a0 While only a few cases of transmission were reported, it seemed most people thought that it was due to isolated exposures.<\/p>\n Previously it was known that Armadillos carry leprosy, the exact same strain as humans, but now it seems that more Armadillos are spreading the disease. However, still not in the USA.\u00a0 It’s mostly in the Brazilian Amazon that humans are infected by Armadillos that carry leprosy. Populations in the rural areas actually have more contact with Armadillos that carry leprosy than Americans.\u00a0 This doesn’t mean that American Armadillos are more safe though.<\/p>\n Can Armadillos that carry leprosy give it to humans?<\/strong><\/p>\n Absolutely. Armadillos that carry leprosy can pass the bacteria on to humans. In a 2018 study, Colorado State University and some colleagues in Brazil captured some Armadillos and tested them for leprosy bacteria.\u00a0 They tested 16 Armadillos and 10 of them had leprosy.\u00a0 Only 7 out of the 146 people were diagnosed with leprosy but the number of people exposed to it was shocking.<\/p>\n Over 60% of the Brazilian people tested had positive antibodies for the bacteria, which is widely accepted as proof of exposure.\u00a0 This doesn’t mean that looking at or being around an Armadillo that carries leprosy will give it to a human.
