Lower-limb ulcers in participants with leprosy sequelae

Introduction Leprosy is a disabling infectious disease that predominantly occurs in the skin and peripheral nerves and is transmitted by contact with pathogenic bacteria through the respiratory tract and broken skin. Leprosy is attributed to infection with Mycobacterium leprae (M. leprae)1 and the more recently discovered Mycobacterium lepromatosis.2 In addition,…
