This article reports the epidemiological characteristics of EHF from 1973 to 1985 in Tongjiang County. Four major pandemics have occurred since 1973. From 1984 to 1985, the incidence rate was significantly increased. The epidemic season accounted for 68.04% of the total incidence from November to December, with obvious autumn and winter peaks. This phenomenon was related to the exposure of population and foci and the increase of rat density. There is a positive correlation between the distribution of rural areas and urban areas. The incidence of epidemic areas in Tongjiang Town has been increasing year by year since 1981, and the incidence of epidemic areas and the incidence of fluctuation have been positively correlated (r = 0.937). Prevention and control measures in the pre-epidemic implementation of large-scale deratization.
