Abstract：Objective To analyze the epidemiological features and prevention and control effects of hemorrhagic fever with renal syndrome (HFRS) in Zixing section before and after the water storage of the Dongjiang Reservoir so as to provide a scientific basis for developing prevention and control measures. Methods We collected HFRS epidemic and rodent monitoring data in Zixing City before and after the water storage of the Dongjiang Reservoir during 1971-2014. Descriptive epidemiologcial methods were used to describe the incidence rates, mortalities and case distribution (regarding time, region and population) of HFRS, serum antibody test results of healthy people, as well as densities, species and pathogen detection results of host animals. Results The average annual incidence rate and case fatality rate of HFRS in Zixing City during 1971-2014 were 6.96/100,000 and 5.93%, respectively. The annual average incidence rate after the water storage (in 1987-2002) was 3.35 times that before the water storage (in 1971-1986) (13.49/100,000 vs. 4.03/100,000). The peak incidence was in 1991 (40.63/100,000). The mouse densities before the water storage (in 1986-1987) and after the water storage (in 1994) were significantly different(6.76% vs. 9.40%, χ2=24.26, P=0.00). The recessive infection rate of HFRS in healthy population before the water storage (in 1986-1987) was significantly higher than that after the water storage (in 2012), with a statistically significant difference (24.66% vs. 2.66%, χ2=31.67, P=0.00). The incidence rates of HFRS decreased significantly after implementing the comprehensive intervention model concerning health education, deratization and vaccine inoculation from 1995 to 2014, and the incidence rates had been maintained at 0-1.10/100,000 since 2006. Conclusions There are epidemic outbreaks of HFRS in Zixing City after the water storage in the Dongjiang reservoir; and hence, establishing large water conservancy projects can significantly affect the prevalence of HFRS. Adopting the integrated intervention model including health education, vaccine inoculation and deratization is the main effective measure for prevention and control of HFRS.
