Abstract: Objective To investigate the epidemic situation of hemorrhagic fever with renal syndrome (HFRS) in the encampment of a troop in Shaanxi province, China, and to provide a basis for troops to control the epidemic situation of HFRS effectively. Methods The epidemic situation of HFRS was analyzed by descriptive epidemiology. The mouse density was monitored by trap-at-night method and powder-trace method. The HFRS antibody was detected by indirect immunofluorescence assay. Results Four cases of HFRS were reported in the troop from November 24th to December 11th, 2009. As for host animals, Apodemus agrarius was the dominant species locally, accounting for 94.38% of the mice trapped in the wild. There were 3.12% of the trapped mice which carried the virus causing HFRS. The mouse density was 3.00% before killing and decreased to zero after killing. A total of 159 sera were tested in the encampment, and 136 of them were positive with IgM. Conclusion The encampment is the epidemic region of field mouse-type HFRS. Surveillance should be strengthened, and comprehensive measures should be taken for prevention and control of HFRS.
