Viral haemorrhagic disease

Rabbit viral haemorrhagic disease (VHD) is a highly contagious disease that affects only rabbits of the Oryctolagus cuniculus species. VHD is also known as rabbit haemorrhagic disease (RHD), rabbit calicivirus disease (RCD), rabbit calici-virus disease (RCVD), and viral hemorrhagic disease of rabbits (VHDR).

It is caused by the rabbit haemorrhagic disease virus (RHDV), also known as rabbit calicivirus (RCV).

Europe
There are a number of different strains of RHD. Currently RHDV2 (VHD-2), a strain found in France in 2010, is spreading throughout Europe. The UK now has access to the new vaccine (Cunivak RHD) that is effective against the new strain. If you or your vet needs information or has questions please read the new facebook post by The Rabbit Welfare Association and Fund.

Joe Carey (UK), author of the VHD-2 facts sheet, contacted Dr. Ghislaine Le Gall-Reculé PhD (in charge of research and scientific/technical studies on rabbit and hare caliciviroses & main author of the French research paper) asking about VHD-2. Responce here.

If you are in the Netherlands you can read: "Bunny owners warned of new hemorrhagic disease killing Dutch rabbits" by the NL Times. More Dutch information here. If you find a dead wild rabbit contact the Dutch Wildlife Health Centre (DWHC) to report it.

Australia & New Zealand
Australia also has a number of variants of RHD. There are plans to release RHVD1 (K5 variant made in South Korea) in Spring 2016 or Autumn 2017. You can follow the latest information on the Facebook group: Against K 5 Virus and For a Vaccine to Save Rabbits from RHDV2.
