Objective To analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Yunnan province, China and to provide reference for the prevention and control of HFRS. Methods The data on HFRS cases in Yunnan were collected to establish a database using Excel 2003. Statistical analysis was performed using SPSS 13.0 to evaluate the incidence and mortality of HFRS, as well as the geographical, seasonal, and population distributions of the cases; analysis of variance was used to determine the regional differences in incidence, and linear correlation analysis was used to determine the population distribution of HFRS. Results From 1976 to 2012, a total of 876 cases of HFRS were reported in Yunnan province, and 50 cases were fatal; the average annual incidence was 0.058/100 000, the average annual mortality rate was 0.0042/100 000, and the fatality was 5.71%. Two epidemic peaks occurred in 1984-1987 and 1998-2006. The cases of HFRS were reported in 75 county-level regions (counties, cities, or districts) of 14 prefecture-level regions (prefectures or cities) in Yunnan. There were significant differences in the incidence of HFRS among the prefecture-level regions. The main epidemic areas (prefecture-level regions) were Kunming, Honghe, Chuxiong, and Dali, where 80.48% of all cases occurred, and particularly 35.50% of all cases were reported in Kunming. The epidemic areas were distributed in the central and northwestern regions at 1500-2500 m elevation; few cases were reported in the mountainous areas (>2500 m elevation) and low-elevation areas (<1500 m elevation) in the southwestern region. The incidence of this disease was found through the whole year, and the epidemic peak was in spring and summer. Young and middle-aged male farmers were the main affected population. Conclusion HFRS cases are widely distributed in Yunnan province, and the central and northwestern basin areas at 1600-2000 m elevation are the main epidemic areas. The surveillance and control of HFRS should be strengthened in the main epidemic areas.
