Methods Epidemiological characteristics of leptospirosis in Neijiang City from 2004 to 2019 were statistically analyzed. The rates were compared by using Chi-square tests, and P<0.05 was considered as statistically significant. Results Totally,193 cases of leptospirosis and 1 death were reported in Neijiang city,with an incidence rate of 0.31/105and a mortality of 0.001/105. Leptospirosis cases were reported in all the years. The incidence peak occurred in 2005, with 52 cases reported and an incidence of1.25/105.
