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.

Is leprosy a genetic disease?

Inheritance. Leprosy is not inherited, but people can inherit an increased risk of contracting leprosy if they are exposed to the Mycobacterium leprae bacteria. Susceptibility tends to run in families, but the inheritance pattern is unknown.

Why are children more susceptible to leprosy?

Children are a high-risk group, as they are more susceptible of acquiring the infection and developing the disease than adults, given their 'unexperienced' immuno- logical system, as well as close and prolonged family contact with possible intra-family sources of infec- tion.

What does leprosy look like on a person?

Signs of leprosy are painless ulcers, skin lesions of hypopigmented macules (flat, pale areas of skin), and eye damage (dryness, reduced blinking).
