Rabbit haemorrhagic disease (RHD), also known as rabbit calicivirus disease (RCD) or viral haemorrhagic disease (VHD), is a highly infectious and often fatal disease that affects wild and domestic rabbits of the species Oryctolagus cuniculus. The infectious agent responsible for the disease is rabbit haemorrhagic disease virus (RHDV), or rabbit calicivirus (RCV), genus Lagovirus of the family Caliciviridae. The virus infects only rabbits, and has been used in some countries to control rabbit populations.
