Why do some people not get leprosy?
Leprosy is mainly spread in airborne droplets such as through coughing or sneezing, by someone who is affected by the disease. However, it will only infect those with poor immunity, who may be undernourished, living in poor conditions and more likely to develop leprosy due to genetics.

Is leprosy spread by touch?
Leprosy is not spread by touch, since the mycobacteria are incapable of crossing intact skin. Living near people with leprosy is associated with increased transmission. Among household contacts, the relative risk for leprosy is increased 8- to 10-fold in multibacillary and 2- to 4-fold in paucibacillary forms.
Can leprosy cure itself?
