title: [A case-control study on the risk factors of epidemic hemorrhagic fever].
abstract: OBJECTIVE
  To study the risk factors of epidemic hemorrhagic fever (EHF).
  
  
  METHODS
  A 1:1 matched case-control study was conducted to analyse EHF risk factors.
  
  
  RESULTS
  One hundred and eighty-five matched pairs were investigated. Five factors were associated with risks of the disease, including rodent activity in house, farm working, travel, annual average income of an individual and ground material of the house, when chi(2) test and logistic regression model were processed respectively. The coefficients of rodent activity in house, farm working, travel, annual average income of an individual and ground material of the house in multivariable Logistic regression model were 1.377, 1.687, 1.630, -1.216 and -0.888, respectively, when P value < 0.05 was observed.
  
  
  CONCLUSIONS
  Factors as high average income of individuals, brick or cement used as material of the ground in the house, seemed to be protective factors of EHF, which were important to the control and prevention of EHF.
