Objective To investigate the epidemic situation of hemorrhagic fever with renal syndrome (HFRS) and the population distribution and virus-carrying status of host animals in Fujian province, China, from 2016 to 2018, and to provide a scientific basis for formulating feasible prevention and control measures for HFRS. Methods The descriptive epidemiological method was used to perform a statistical analysis of HFRS case data and host monitoring data in Fujian which were reported in Surveillance Information Reporting and Management System in 2016-2018. The ratio was compared by χ2 test. Results A total of 1 184 HFRS cases were reported in Fujian from 2016 to 2018, with a mean annual incidence rate of 1.02/100 000, and there were 2 deaths, resulting in a mortality rate of 0.17%. Most cases were observed in Nanping, Quanzhou, and Sanming cities. The cases were reported all year round, with the peaks in March to May and November to February, and the peak in spring was higher than that in winter. The high-risk population was young men, and the highest incidence rate was observed in men aged 65-70 years and women aged 60-65 years. A total of 12 854 effective cages were set in the surveillance sites of Fujian and 845 rodents were captured, with a mean density of rodents of 6.57%. A total of 845 lung samples were collected, among which 48 were positive, and the 3-year mean virus-carrying rat index was 0.06. Conclusion The incidence rate of HFRS in Fujian province tends to first decrease and then increase from 2016 to 2018, with high rodent density and virus-carrying rate, and there is still a risk of HFRS outbreak. It is recommended to adopt comprehensive prevention and control measures of vaccination and deratization.
