Leprosy will be eliminated when we detect all patients and cure them by using multidrug therapy (MDT). Elimination means bringing the disease burden down to a very low level. This will lead to a reduction in the source of infection, so that leprosy is likely to disappear naturally as it already has in many parts of the world. WHO has defined “elimination” as a prevalence rate of less than 1 case per 10,000 inhabitants.
