Phylogenetic relationships for 29 rodent and shrew hantavirus strains derived from Shenzhen city, China. The tree, which was based on a 359-bp sequence of the L fragment of the hantavirus, was built using a neighbor-joining algorithm implemented in Mega version 7. Bootstrap values (> 70%) are shown at specific nodes. Scale bars reflect the number of nucleotide substitutions per site. Seoul virus and Shrew virus are indicated on the right. The strain designations are indicated at each branch. The newly determined Shenzhen rodent and shrew strains are indicated via circles and triangles, respectively.
