Objective To take effective strategies and measures for the prevention and control of hemorrhagic fever with renal syndrome （HFRS） endemic areas by investigating its dynamic geographical boundaries in Shandong Province, China. Methods The incidence of HFRS from 1982 to 2008 in Shandong Prvince, China, was detected with inverse distance weighting （IDW） interpolation based on geographical information system （GIS）. Dynamic geographical boundaries of HFRS endemic areas in Shandong Province, China, were analyzed by geographical boundary analysis. Results The HTN-type endemic areas of HFRS were located in Linyi City in phase 1 （1982-1986）, the SEO-type endemic areas of HFRS were located in Jining City in phase 2 （1987-2003）, and the endemic areas of HFRS in Jining City gradually disappeared and the endemic areas of HFRS with mixed-types of reservoir rodents were located in Linyi City in phase 3 （2004-2008）. Meanwhile, new endemic areas emerged in the northwestern Shandong province, China. Conclusion The SEO-type endemic areas of HFRS are located in western Shandong Province, China, and the HTN-type endemic areas of HFRS are located eastern Shandong Province, Chin, indicating that the endemic areas of HFRS should be vaccinated and rodents should be controlled.
