Result: Subjects in this study were dominated by males (66.8%) and aged > 14 years (95.3%). The most common type of leprosy was multibacillary (MB) (86.2%), and erythema nodosum leprosum (ENL) was the most leprosy reaction (20.3%). Majority of the subjects experienced disability in the hands (26.6%), in grade 1. Conclusion: Leprosy cases in Indonesia are mostly experienced by adult males. The most common type of leprosy is MB, with ENL being the most common leprosy reaction. Grade 1 disability is the most prevalent, therefore proper education is necessary to keep patients from progressing to grade 2 disability.
