Abstract

Objective To study the epidemiological charactristics of Hemorrhagic fever with renal syndrome(HFRS) in Zhejiang province for preventive measures against the disease. Methods Animal hosts were investigated in surveillance area during 1984-2001.The serum of the patients were collected to test. Analysis both the rodents density and rodents virus carried rate. Results 12 027cases were reported in five surveillance areas of Zhejiang Province with an annual incidence of 35.52/100,000. 86 patients died with a fatality rate of 0.72%. HFRS was primarily a diease of the youth male peasants. Most infections happened in November to next January and April to June. The average density of rodents is 10%. The serum positive rate of patients is 67.81%. Apodemus mode( 60.91%) is the main type. Conclusion Zhejiang Province belonges to mixed epidemic area of HFRS and the Apodemus mode is primary.
