Rabbit hemorrhagic disease virus (RHDV)
RHDV (also referred to classical RHD) only affects adult European rabbits (Oryctolagus cuniculus). This virus was first reported in China in 1984,[1] from which it spread to much of Asia, Europe, Australia, and elsewhere.[2] An antigenic variant of RHDV, termed RHDVa, was first described in 1997 and has spread around the world causing epidemics in China, Korea, the United States, Mexico, Japan, Reunion Island, and Europe. There have been a few isolated outbreaks of RHDVa in the United States and Mexico, but they remained localized and were eradicated.[3]
In 2010, a new lagovirus with a distinct antigenic profile was identified in France. This virus also caused rabbit hemorrhagic disease but behaved differently from RHDVa in that it affected vaccinated and young European rabbits as well as hares (Lepus spp.).[4] All these features strongly suggested that the virus was not derived from RHDVa but from some other unknown source.[4] The new virus was named rabbit hemorrhagic disease virus 2 (abbreviated as RHDV-2 or RHDVb). RHDV-2 is distinct enough from RHDVa that the two require different vaccines, which are only partially cross protective. RHDV-2 has since spread to the majority of Europe as well as to Australia, Canada, and the United States.
The two strains of rabbit hemorrhagic disease virus currently of medical significance are RHDVa and RHDV-2.
