Since the early 1950s, China has made some researches on leptospirosis (leptospirosis) in terms of its epidemiological features, sources of infection and zooplanktons, isolation and identification of flora (type), clinical types, treatment and control strategies Significant progress. This article is intended to review some of its epidemiological issues. First, the epidemic leptospirosis is one of the most common zoonosis, widely distributed and popular in our country. Since the discovery of the pathogen in 1934, it has been more than 50 years old. My country since 1955 as a legal notifiable disease report.
