Leprosy is caused by Mycobacterium leprae and has been known since biblical times. The mechanism of transmission of leprosy consists of prolonged close contact between susceptible and genetically predisposed individuals and untreated multibacillary patients. Transmission occurs through inhalation of bacilli present in upper airway secretion. The nasal mucosa is the main entry or exit route of M. leprae. The deeper understanding of the structural and biological characteristics of M. leprae, the sequencing of its genome, along with the advances in understanding the mechanisms of host immune response against the bacilli, dependent on genetic susceptibility, have contributed to the understanding of the pathogenesis, variations in the clinical characteristics, and progression of the disease. This article aims update on epidemiological, clinical, and etiopathogenic leprosy aspects.</strong></h2>}, number={2}, journal={International Journal of Allied Medical Sciences and Clinical Research}, author={Dr. R.
