Abstract:
Objective To investigate the epidemiological characteristics and factors of hemorrhagic fever with renal syndrome (HFRS) during 1958 to 2007 in Fuyang.Methods Descriptive study method was used to analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome.The incidence peak of hemorrhagic fever with renal syndrome was computed by using rotundity distribution.The correlation was analyzed between incidence and virus index by Pearson correlation.Results 40 002 HFRS cases was reported during 1958 to 2007 in Fuyang and 2381 cases were dead.The average incidence and fatality rate of HFRS were 11.99 per 100 thousand and 5.95 percent respectively.Eight counties all had cases.Yingshang county had the highest cases and Jieshou city had the highest fatality rate.Since 1958,there're 4 incidence peak in Fuyang.The period of high incidence was during November to January of next year and the peak of incidence rate was on December 13.Indoor density and field density of mouse were 9.84 percent and 7.91 percent respectively.Virus rate of indoor and field of mouse were 9.21 percent and 6.99 percent respectively.During 1984 to 2007,the correlation coefficient between virus index and incidence was 0.58.In room brown mouse was the most before 2000,but then house mouse become the most.In open country heavy line Japanese fieldmouse is the most mouse all the time.Conclusions In Fuyang,the focus of HFRS is exist widely.Density and virus rate of mouse will directly affect the incidence.So surveillance among mouse should be strengthened.
