Global leprosy (Hansen disease) update, 2022: new paradigm – control to elimination

ince the introduction of multidrug therapy (MDT), there has been significant progress in reducing the prevalence of leprosy and the occurrence of new cases. Global strategies have evolved with progress in reducing the disease burden. Encouraged by the decrease in the number of cases on treatment, the World Health Assembly passed a resolution calling on Member States to accelerate efforts towards global elimination of leprosy as a public health problem by 2000. Most countries reached the milestone by 2010. The global strategies for 2006–2015 focused on sustaining high-quality leprosy services and early diagnosis. Reduction in the disease burden was measured in terms of grade-2 disability (G2D) or visible deformities in new cases. Since 2016, the strategies have included reduction of stigmatization of people with leprosy.
