Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Rabbit calicivirus has been used in Australia as a biological control agent since 1995. In Australia, RHDV2 was first detected in European rabbits in the Australian Capital Territory in May 2015 (immediate notification sent to the OIE on 7 July 2015) and has since spread to New South Wales, Victoria, Northern Territory, Tasmania and South Australia. Routine testing of three dead wild European hares, two in South Australia and one in Victoria, found rabbit haemorrhagic disease virus 2 (RHDV2). RHDV2 has not previously been detected in European hares (Lepus europaeus).
