BMC Infectious Diseases

Table 1 The summary of rodent density, species composition and virus-carrying rate within six surveillance points since 2007 to 2016^a

Area	No. rattraps	No. rats	Density	Virus-Carrying Rate	Rattus norvegicus	Mus musculus	Tscherskia triton	Apodemus agrarius	Other species
Field	89,367	471	0.53%	1.74%	298 (63%)	29 (6%)	127 (27%)	3 (1%)	14 (3%)
Residential	92,599	2250	2.43%	0.05%	1902 (85%)	342 (15%)	0	0	6

^aThe number of rattraps, rats and the individual species were the summation of all surveillance points. Density and virus-carrying rate were the average of all serveillance points. The percentages in brakets represent the proportions of the induvidual species to the all rodents captured in field or residential area
