Background: This epidemiological study aimed to analyse both the distribution and characteristics of leprosy in an endemic province in Northwest China.Methods: The medical records of leprosy patients in the province of Shaanxi, China, from 1998-2018 were collected from the Chinese Leprosy Management Information System (LEPMIS). Epidemiological variables were analysed in this study.Results: A total of 477 new cases were diagnosed between 1998 and 2018 in this region. The average annual detection rate was 0.070/100,000 population, and the average annual prevalence was 0.305/100,000 population. The mean age of the newly diagnosed patients was 46.7 years, and the ratio of males to females was 2.5:1. There were 399 cases (83.6%) of multibacillary (MB) leprosy. One hundred forty-eight patients (31.0%) had grade 2 disability. The mean diagnosis time for new cases was 62.0 months.Conclusion: This epidemiological study showed that the characteristics of newly diagnosed leprosy cases in our province were a long time to diagnosis and a high rate of deformity, indicating the need for actions focusing on early diagnosis and treatment and strengthening the detection of leprosy in low-prevalence areas.

The mean age of new patients was 46.7 years, and the ratio of male to female was 2.5:1. There were 399 cases (83.6%) of multibacillary (MB) forms. 148 cases (31.0%) had grade 2 disability. The mean delay in diagnosis for new cases was 62.0 months. Conclusion: The epidemiological study showed that the characteristics of the new leprosy cases in our province were still long delay in diagnosis and high rate of deformity, which indicated the need of actions of stimulating early diagnosis and treatment, and strengthening the detection of leprosy in low prevalent areas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
