[Objective] To analyze the prevalence of hemorrhagic fever with renal syndrome (HFRS) in Yingkou and provide a scientific basis for preventing and controlling the occurrence of HFRS. [Methods] The data of HFRS in Yingkou from 2003 to 2007 were analyzed. [Results] A total of 563 cases of HFRS occurred in Yingkou from 2003 to 2007, with an average annual incidence of 5.66 / 100,000 and 4 deaths. The annual incidence rate (/ 100,000) was 2.36 in 2003, 7.95 in 2004, 8.22 in 2005, 4.42 in 2006 and 2.01 in 2007. The average annual incidence rate (/ 100000), the station front area was 3.83, the west urban area was 3.28, the old border area was 7.02, the Bayuquan area was 21.07, the Dashiqiao city was 3.93, and the Gaizhou city was 3.45.563 HFRS cases, Male accounted for 79.75%, 20-39 years old accounted for 45.29%, farmers accounted for 55.77%; March to June total incidence of 297 cases (52.75%). 1 023 domestic rats were captured, all of which were Rattus norvegicus. A total of 1 023 Rattus norvegicus and 65 positive HFRS viruses were detected, with a rate of 6.35%. [Conclusion] The incidence of HFRS in Yingkou was obviously spring peak, and the male and young farmer was the high incidence of HFRS.
