  1. Rodent snaps in each year were 5427, 2758, 5228, 11383, 4191 for 2010, 2011, 2012, 2013 and 2014, respectively. The capture rate each year was calculated by the number of rodents captured/snap number × 100.
  2. *Indicated that a significant correlation between HFRS incidence rate and the total capture rate of field rodents (r = 0.938, P = 0.018) and the capture rate of Mus musculus (r = 0.037, p = 0.011).
