- M. leprae multiplies slowly and the incubation period of the disease, on average, is 5 years.
- Symptoms may occur within 1 year but can also take as long as 20 years or even more to occur.
- The disease mainly affects the skin, the peripheral nerves, mucosa of the upper respiratory tract, and the eyes.
- Leprosy is curable with multidrug therapy (MDT).
- Leprosy is likely transmitted via droplets, from the nose and mouth, during close and frequent contact with untreated cases.
