How is leprosy spread?

There is much stigma surrounding leprosy and many people believe it is a punishment or a curse. The truth is it is simply a mildly infectious disease. It is not hereditary and cannot be caught by touch. Scientists believe it is caught through droplets of moisture passed through the air from someone who has leprosy but has not yet started treatment. It takes years, however, of living in close proximity with an untreated leprosy patient to catch the disease. Around 95 per cent of people are thought to be naturally immune to leprosy.
