Is leprosy caused by poor hygiene?
Adjusted analyses showed open defecation and lack of soap were correlated with leprosy cases. Overall, these results support a relationship between WASH factors and leprosy cases. These results are thus important due to the burden of both poor WASH and leprosy in LMICs.
Who is the most common victim of leprosy?
Leprosy can develop at any age but appears to develop most often in people aged 5 to 15 years or over 30. It is estimated that more than 95% of people who are infected with Mycobacterium leprae do not develop leprosy because their immune system fights off the infection.

leprae from armadillos have been found in almost two-thirds of the autochthonous human leprosy cases in Southern USA21 . Table 1 shows published studies on the natural infection of M. leprae in wild armadillos. These studies strengthen the hypothesis of armadillos as a zoonotic source of M.
