(CNN) Leprosy is a disease most people think ended in the Middle Ages, but a new study shows that it's not a thing of the past. In the clinic's electronic health records, they found nine patients diagnosed with leprosy over a 23-year period. The study authors emphasized that, though it's rare, the disease should still be considered when diagnosing patients. According to the World Health Organization , those places include the Democratic Republic of Congo, Ethiopia, Madagascar, Mozambique, Nigeria, Tanzania, Bangladesh, India, Indonesia, Myanmar, Nepal, the Philippines, Sri Lanka and Brazil. Each of those countries reported 1,000 new cases of leprosy, also known as Hansen's disease, in the past five years.
