Is Leprosy Contagious?

Many people wonder, "Is leprosy contagious?" Yes, but leprosy is far less contagious than other infectious diseases. It seems that it is only contagious when a person has untreated leprosy. Once the disease has been treated, a person becomes noninfectious within a short period of time. Most specialists agree that more than 95 percent of the world's population has a natural immunity to the disease.
 
In addition, not all forms of this disease are contagious. For example, the tuberculoid or paucibacillary form is not contagious.
