Objective: To study the infectious source of Leptospira in Jiangyou City (referred to as Leptospira) in recent years and provide a scientific basis for the prevention and treatment of the disease. Methods: The main host animal leptospirosis host mice, pigs, bovine bacteria and rat density, population composition and so on. Results: The average incidence of mice in this city was 11.3 4%. The average age of rats was 63.64%. The average incidence rate was 17.5 2%. Leptospira, isolated from leptospirosis patients and animals, accounted for 98.5%. Conclusion: Apodemus agrarius is the main source of infection of paddy field leptospira in Jiangyou City, and the change of epidemic flora is one of the important factors causing the epidemic.
