Where does the leprosy bacteria come from?
Researchers from the Institut Pasteur, Paris, France theorise that East Africa is the more likely place of origin of leprosy. The scientists studied the genetic material from 175 samples of Mycobacterium leprae, the bacterium that causes leprosy, from 21 countries (Science, May 13, Vol 308, No 5724).

How did leprosy begin?
Dr. Gerhard Henrik Armauer Hansen of Norway was the first person to identify the germ that causes leprosy under a microscope. Hansen’s discovery of Mycobacterium leprae proved that leprosy was caused by a germ, and was thus not hereditary, from a curse, or from a sin.
How can leprosy be transmitted?
Scientists currently think it may happen when a person with Hansen’s disease coughs or sneezes, and a healthy person breathes in the droplets containing the bacteria. Prolonged, close contact with someone with untreated leprosy over many months is needed to catch the disease.
How can leprosy be avoided?
Is it possible to prevent leprosy? Prevention of contact with droplets from nasal and other secretions from patients with untreated M. leprae infection is currently the most effective way to avoid the disease. Treatment of patients with appropriate antibiotics stops the person from spreading the disease.
Why are 95% of people immune to leprosy?
It is estimated that more than 95% of people who are infected with Mycobacterium leprae do not develop leprosy because their immune system fights off the infection. People who develop leprosy may have genes that make them susceptible to the infection once they are exposed.
What is the name of the bacteria that causes leprosy?
