Does Leprosy Spread by Touch?

Doctors aren't exactly sure how leprosy spreads. Leprosy is not very contagious. You can't catch it by touching someone who has the disease. Most cases of leprosy are from repeated and long-term contact with someone who has the disease.

How does leprosy spread from one person to another?

When a person with leprosy coughs or sneezes, they may spread droplets containing the M. leprae bacteria that another person breathes in. Close physical contact with an infected person is necessary to transmit leprosy.

Is leprosy easily transmitted?

Leprosy was once feared as a highly contagious and devastating disease, but now we know it doesn't spread easily and treatment is very effective. However, if left untreated, the nerve damage can result in crippling of hands and feet, paralysis, and blindness.
