Abstract

•
We identified one RHD case caused by a new RHDV variant (GI.2) in China through HA, TEM, and genome sequencing.
•
This is the first study to demonstrate that GI.2 can replicate efficiently in the reproductive system.
•
Our evidence suggests that GI.2 might be introduced into China by contaminated rabbit semen.
