Summary

This study looks back at the medical records of 130 people diagnosed with Hansen's disease (leprosy) in Costa Rica between 2018 and 2025. The goal is to describe the patients, how the disease was diagnosed, what treatments were used, and what complications occurred. No new treatments are being tested; instead, researchers hope to learn more about how leprosy is managed in routine care.
