Nine-banded armadillos are one of a handful of mammals known to contract leprosy (also known as Hansen's disease); range expansion thus leads to public health concerns about whether this might increase human exposure to infected animals. We collected blood samples from 61 road-killed armadillos over two summers (2021 and 2022) in Tennessee, a US state near the northern extreme of the species' current range, and screened them for exposure to Mycobacterium leprae, the causative agent of leprosy. All animals were seronegative, providing no evidence that range expansion is increasing the distribution of leprosy in the US.</p>
