Objectives To analyze epidemiological characteristics of leprosy in Sichuan province from 2000 to 2017.Methods Case data of all new leprosy patients in Sichuan province from 2000 to 2017 were collected. A retrospective analysis of its epidemiological characteristics was performed by using SPSS 19.0 software.Results A total of 3 208 cases of leprosy were detected during 2000 to 2017, of whom 2 197 (71.28%) were male, 885 (28.72%) were female. The younger cases whose ages were less than 14 were 82 (2.66%), and the cases with grade 2 disabilities were 614 (19.92%). The mean age of male was older than female (41.64±14.26 vs. 38.89±15.12 years, P<0.05). The grade 2 disability rate of male was significantly higher than that of female (20.94% vs. 17.40%, P<0.05). Self-report was the most common method of discovery. But the ratio of male who were detected through contact examination was significantly lower than that detected through dermatological clinic, self-report, clues check and report (the ratio of male to female was 1.57, 2.38, 2.88, 2.48, 2.37, respectively, P<0.05).Conclusions The case detection of leprosy declines annually in Sichuan province from 2000 to 2017, especially in high-endemic area and male patients. Female patients are younger than male patients when they are detected. The grade 2 disability situation of male patients is significantly more serious than that of female patients. Self-report is the most common way of discovery, while women are more passive.
