Prevention & Expectations
What can be done to prevent the infection?
Prevention involves avoiding close physical contact with a person who has untreated leprosy.
What are the long-term effects of the infection?
Leprosy damages nerves and causes a loss of sensation in the skin. The person can have repeated injuries without realizing it, since there is no perception of pain. The injuries can eventually result in ulcers, broken bones, and deformities. Nerve damage and physical disabilities can be permanent.
What are the risks to others?
Leprosy is contagious and can be spread to others through contact with nasal secretions from an untreated, infected person.
