The virus probably originated from a less virulent form present in rabbit populations for many years. Rabbit haemorrhagic disease (RHD), also known as rabbit calicivirus disease, is a highly contagious and acute fatal disease of wild and domestic European rabbits (Oryctolagus cuniculus). The virus was accidentally released into the wild rabbit population in Australia, where subsequently it was deliberately spread as a biological control. After it was first reported in China in 1984 (Liu et al. ELISA methods for the diagnosis of RHDV infection are of rabbits infected with a non-pathogenic rabbit haemorrhagic disease-like virus. Rabbit Hemorrhagic Disease (RHD) calicivirus is spread by oral, nasal and parenteral transmission. Update 2018: What rabbit owners need to know about the K5 calicivirus strain release. Registration is now open for Leschenault Biosecurity Group’s summer 2024-2025 Rabbit Control Calicivirus RHDV1-K5 Release Program. First described in China in 1984, the virus rapidly spread worldwide and is nowadays considered as endemic in several countries. Minister for Primary Industries and Water, Jane Howlett, said she has spoken with many farmers who have been battling with rabbits in [] Background.

Feline calicivirus (the only member of the group with a seemingly ubiquitous and K5 is a Korean rabbit calicivirus deliberately selected to kill more rabbits in cooler and wetter areas such as the Adelaide Hills and South East Australia. The new virus contains significant differences from the previously characterized RHDV isolates in terms of pathogenicity, viral titer, tropism, and primary sequence of There are two viruses that are released to control wild rabbits, Calicivirus (also known as Rabbit Haemorrhagic Disease Virus or RHDV) and Myxomytosis. Diagnosis: history, signs. RHDV2 Rabbit Calicivirus A new strain of the rabbit calicivirus has been confirmed in a single wild rabbit found on a Marlborough farm. VHD originated in 1984 in the People’s The virus was accidentally released into the wild rabbit population in Australia, where subsequently it was deliberately spread as a biological control. 1) is a calicivirus in the genus Lagovirus that has been widely utilized in Australia as a biological control agent for the management of overabundant wild European rabbit (Oryctolagus cuniculus) populations since 26 May 2005. The detection of RHDV2 in flies at both control Four out of the five major calicivirus groups were known to cause disease in humans at the time the RCD/RHD virus was legalised as a biocontrol of European rabbits in Australia. , 2012; estimated that 12 million Australian dollars have been spent over 8 years of research and development before RHDV was accidentally released in unknown farmers in New Zealand With scientists predicting yet another drought-stricken summer, the release of the rabbit calicivirus disease (RCD) couldn’t have been too soon. Rabbit hemorrhagic disease (RHD), also known as rabbit calicivirus disease (RCD) and viral hemorrhagic disease (VHD) affects European rabbits (Abrantes et al.

It is specific to the European rabbit, and once a rabbit shows symptoms, death is rapid. New strains of the virus being released and whilst the vaccination cannot provide 100% protection, it certainly reduces the risk of Several conventional and recently available tools are available for an integrated control of European rabbits in Australia. Calicivirus and myxomatosis in rabbits are two serious diseases which can cause death. , hunting and poisoning. Use rabbit-proof fencing, and/or control measures such as baiting, warren destruction or removing vegetation that might harbour wild rabbit populations (see Control Techniques for more Rabbit hemorrhagic disease virus 2 (RHDV2; Caliciviridae, Lagovirus europaeus), the cause of a highly transmissible and fatal lagomorph disease, has spread rapidly through the western United States and Mexico, resulting in substantial mortality in domestic and wild rabbits. New Zealand has three strains of Rabbit Haemorrhagic Disease Virus (RHDV), which is also known as rabbit calicivirus. MAF Policy, MAF, Wellington, New Zealand, p 29. However, a vaccine is available for domestic Since their introduction in 1859, European rabbits (Oryctolagus cuniculus) have had a devastating impact on agricultural production and biodiversity in Australia, with competition and land degradation by rabbits being one of the key threats to agricultural and biodiversity values in Australia. ). What is RHDV1 K5? RHDV1 K5 is a variant of rabbit haemorrhagic disease virus (RHDV1), which causes a fatal haemorrhagic disease in the European rabbit (Oryctolagus cuniculus). 02. The best protection is to vaccinate rabbits with the “Filavac” vaccine. , 2005a, Oka et al. “Melynda, while rabbit populations did eventually rebound after the introduction of myxoma, its initial release was extremely successful in Australia, eliminating over of the rabbits. The decision involved two clearly different considerations: one focused on the risks of RCD to ecosystems and other species; while the other examined its potential as a biological control agent and the organisational arrangements for its management. Symptoms of RHDV1 (and variants) include: Depression; Lethargy; Neurological problems; Anorexia . It spread rapidly across mainland Australia, most likely assisted by flies, drastically reducing rabbit populations – although being less effective Calicivirus is spread from flies, mosquitos and other rabbits. The Department of Primary Industries recommend that rabbit owners take the following extra precautions: Outbreaks of RHDV2 are ongoing in the United States, and the virus has been found in wild, feral, and domestic rabbit and hare species. Both virus types have been deliberately released into Australia as a control method for the wild rabbit population. Rabbit Calicivirus Disease: Magic Bullet or Pandora's Box? A Case Study on Biological Controls by Gary M. It acts more slowly than calicivirus. 5 kb. The virus was originally isolated For many caliciviruses, feasible cell culture systems are missing. In 1995, as a result of a laboratory accident in southern Australia, the virus escaped from quarantine and killed 10 million rabbits in 8 weeks. RHDV2 Outbreak in the Southwestern U. The LBG will once again facilitate a Calicivirus RHDV1-K5 (K5) Release Program with participating landholders across our operational area commencing in mid-January 2025 with targeted releases anticipated through The outbreak of Rabbit Calicivirus Disease (RCD or RHD) in late 1995 at Kinchega National Park (NP) in and western NSW, Australia, coincided with intensified warren ripping and other rabbit The release of myxoma virus (MYXV) and Rabbit Haemorrhagic Disease Virus (RHDV) in Australia with the aim of controlling overabundant rabbits has provided a unique opportunity to study the initial spread and establishment of emerging pathogens, as well as their co-evolution with their mammalian hosts. The strain of Rabbit Haemorrhagic Virus Disease – called RHDV2 – is widespread in Europe and Australia, but this is the first time it has been found in New Zealand. We heard rumours that RHDV2 rabbit calicivirus was ‘accidentally’ released from a government lab. This virus is being released as a biocontrol measure to manage wild European rabbits. Some might be due to genetic factors, or other environmental factors, and some are contracted from other rabbits – in either case, it’s important to spot the signs on time to make sure your pet has the best chances of recovering from whatever ails them. There are a number of different strains in Australia. The release of a new strain of RHDV (RHDV1-K5) into the wild rabbit population in NZ was approved by the Ministry for Primary There are several strains of rabbit calicivirus (also known as Rabbit Haemorrhagic Disease Virus (RHDV)) in New Zealand: RHDV1 is widespread.

In Australia and New Zealand where rabbits are Other Names: Viral Hemorrhagic Disease of Rabbits, Rabbit Calicivirus Disease. As a 1998 press release claims: The release of Rabbit Calicivirus (RCD) in 1996 was the most effective attempt at rabbit control since the introduction of myxomatosis in the 1950s. The virus was accidentally released into the wild rabbit population in Australia, where subsequently it was deliberately spread as a biological control. A Chinese RHDVa strain was found in NSW RHDV 1 – Original virus released in 1995 (also known at the Czech strain). • It was illegally introduced into RHDV damages internal organs such as the liver and intestines and may cause bleeding. Smith et al. The second type is the calicivirus (or Rabbit Haemorrhagic Disease Virus (RHDV)) group, which cause the clinical condition commonly known as ‘Rabbit Haemorrhagic Disease’. RHDV2) (Patel et al. Introduction. Rabbit hemorrhagic disease (RHD) is caused by a calicivirus and is associated with illness and death in up to 90%–100% of susceptible rabbit populations (1–3). recently released a new agent, rabbit haemorrhagic disease, known as rabbit calicivirus disease (RCD) in Australia and New Zealand, to control rabbits. Rabbit haemorrhagic disease: does a pre-existing RHDV-like virus reduce the effectiveness of RHD as a biological control in Australia? Cause: Calicivirus, RHD strain 2. Outbreaks of rabbit calicivirus disease have since occurred in Australia (1995), New Zealand (1997), and Cuba (1997). RHDV1 K5 (Korean strain) is a naturally occurring variant of RHDV1, registered as a biological control agent in Australia and released in March 2017. 3. , 2019) undertook RHDV serology within the target rabbit populations prior to K5 release. BIO IMMUNOLOGY. Only one strain (the Czech CAPM-v351) of rabbit haemorrhagic disease virus (RHDV) has been released in Australia and New Zealand to control pest populations of the European rabbit O. Rabbit Calicivirus (RCD) accidentally escaped from a quarantine research area in 1995. The disease was first detected in California in May 2020, prompting an It is not recommended to release RHDV1 into a population of rabbits with high immunity. The acronym RHDV (rabbit RHD Fact Sheet Quick Facts: Known as RHD (Rabbit Hemorrhagic Disease), RCD (Rabbit Calicivirus Disease) or VHD (Viral Hemorrhagic Disease) It is a highly infectious viral disease that can infect domestic rabbits. Report of the Rabbit Calicivirus Human Health Study Group; 1996. Rabbit owners need to either ensure their pet rabbits' vaccination records are up to date or get In vitro cultivation of caliciviruses indicates that these pathogens have been emerging periodically from ocean sources for 65 years . There have been no detected infections in domestic rabbits with the controlled calicivirus RHDV1 K5 release that was undertaken The “K5” VIRUS ONLY AFFECTS RABBITS. More than 600 release sites were selected nationally. o There was a loss of public confidence in those responsible for managing the control programe. , 1984), RHD spread rapidly around the world. 1. In Australia there are two diseases that rabbits can contract. With over $115 million of lost production yearly to the wool industry, and a $600 million total cost in export income to the agricultural industry, not to mention the immeasurable environmental where Y ij were the dependent categorical variables, occurrence of myxomatosis or RHD on each visit-farm, YE i was the year effect (30: from September 1988 until September 2018), MO j was the month effect (12), and e ijk was the residual effect. Rabbit Haemorrhagic Disease (Calicivirus) to be released . RHDV1 K5 was introduced here in March 2018 (to control wild Rabbit Calicivirus Disease (RCD) progresses very quickly and usually by the time you Releasing calicivirus (RHDV K5) to boost rabbit control. If a pet rabbit is showing sig This was not long after Australia had a Calicivirus outbreak, killing more than 10 million rabbits within 8 weeks. Rabbit haemorrhagic disease (RHD) is a highly infectious and fatal disease of the European rabbit (Oryctolagus cuniculus). The virus is present in urine and feces from infected rabbits, thus contaminated bedding can be a source of infection. RCD/RHD has existed in its current state only since it first appeared in China in 1984 and little is known about the origin of the disease. Over time, rabbits have developed some genetic resistance to the Czech strain (as they did for myxomatosis) and its effectiveness as a biological control agent has been reduced. In August 2022, RHDV2 was detected for the first time in Pennsylvania in a domestic rabbit facility in Fayette County. The virus that causes RHD (called rabbit haemorrhagic disease virus or RHDV) is spread through rabbit-to-rabbit contact 1. SO what exactly is this disease, Background. RHDV1 K5 was introduced here in March 2018 (to control wild rabbits). In Australia, RCD continues to affect rabbit Rabbit hemorrhagic disease virus is a calicivirus of the genus Lagovirus and is the causative agent of rabbit hemorrhagic disease (RHD) (Abrantes et al. RHD was first described in China in 1984 and spread In 1995, a strain of calicivirus, later called RHD or Rabbit Haemorrhagic Disease, was inadvertently released from its quarantine trials zone on South Australia's Wardang Island. They found that in domestic rabbits from the United States, 2 different forms of rabbit calicivirus with differences in pathogenicity are circulating. Calicivirus RHDV1 K5 (“K5” Strain of the Rabbit Haemorrhagic Disease If you suspect a rabbit may have died of calicivirus, you can request a free test kit by sending an email to rabbitcalicivirus@csiro. Our attention was drawn particularly to the data and comments regarding rabbit hemorrhagic disease (RHD), a recently emerged and devastating disease of just one rabbit species, Oryctolagus cuniculus. The virus rapidly spread through wild and domestic rabbits in Europe, causing Introduction. While the breach The disease is caused by the rabbit haemorrhagic disease virus 1(RHDV1) (Czech 351 strain) and its release in Australia has controlled rabbit populations since 1996. 4–8. A strain of Rabbit Haemorrhagic Disease Virus (RHDV1) was formally released in Australia in 1996. Rabbits are estimated to cost the country $50 million in lost agriculture and $25 million in rabbit control, e. (Emerg Infect Dis 1998; 1:13-20) on calicivirus emergence from ocean reservoirs. Previously, five rabbit calicivirus variants were known to circulate in Australian rabbits: the two biocontrol agents RHDV1 and K5, two pandemic viruses RHDV2 and an RHDV1a variant, and the benign RCV-A1 (rabbit Serological cross reactivity between the virulent rabbit haemorrhagic disease virus (RHDV) and the closely related but non-pathogenic rabbit calicivirus (RCV) makes it difficult to study the epidemiology of each virus and the interaction between them when both viruses co-circulate in wild rabbit populations. In 1950 the disease was released to reduce the A similar observation was reported for a related non-human pathogenic calicivirus strain, the rabbit hemorrhagic disease virus (RHDV, genus Lagovirus). au with your postal address. Pet rabbits can be vaccinated for some strains of calicivirus. 2017 May 17;83 (11 Antibodies that cross to interact via their impacts on rabbit abundance levels, and 2) introduction of RCD can suppress myx-omatosis prevalence. The virus that causes RHD (called rabbit haemorrhagic disease virus or RHDV) is spread through rabbit-to-rabbit contact Crosby TK, McLennan J (1996) Potential vectors of rabbit Calicivirus disease (RCD) in New Zealand: a review. For more than four decades, global populations of both wild and domesticated European rabbits were ravaged by the highly fatal and contagious rabbit haemorrhagic disease (RHD) (Liu et al. o The release occurrred at a time and under conditions that did not have the greatest possible impact on the rabbit population.

Other species, even pets that Environmental Persistence of Rabbit Hemorrhagic Disease Calicivirus. It is safe to pets and wildlife. Prognosis: variable; lower mortality than RHD1. The best time of year to release the virus is in autumn, but mid-to-late spring and summer are also good times. Incubation: The incubation period is approximately The paper discusses the Australian Rabbit Calicivirus Disease (RCD) Program, an attempt at the biological control of wild rabbits, as an example of how technoscience in 'Mode-2 society' works. 2012), causing substantial economic losses in the rabbit meat and fur industry and significant impacts to wild populations and their Ongoing rabbit disease monitoring by CSIRO’s team continues to provide critical data which is fed into a publicly available and continually updated rabbit calicivirus map of Australia, and provides information about which viruses are circulating, where they are circulating and when they are circulating. VHD2 is a less acute onset than VHD1 virus infection with the European rabbit (Oryctyolagus cuniculus), as the only known host. Avoid contact with In a global world there is always the chance of unwanted pests or diseases entering the country. Rabbits with RHD present with clinical signs after a Rabbit Calicivirus Disease (RCD) History Rabbit Calicivirus Disease (RCD) is a viral disease which affects only European rabbits.

RHDV was first reported in China in 1984 and subsequently spread to South Korea by 1985, various European countries A single domestic rabbit which died in Blenheim has tested positive for the new RHDV2 strain, while one outbreak of the original RHDV1 Czech strain was detected in samples from seven domestic rabbits in Canterbury. Regional Leader Biosecurity Graham Sullivan said the result was in line with expectations, reinforcing the important point made throughout the campaign that this release was just one of the tools in the rabbit control toolbox Rabbit calicivirus disease (RCD) is a very serious infectious disease that can kill pet rabbits in Australia. Introduction: Rabbit haemorrhagic disease (RHD), previously known as calicivirus or rabbit calicivirus disease (RCD), has been highly effective in reducing rabbit populations across most of Australia. Sydney: Meat Research Corporation; 1996. It is expected to persist in these areas for the foreseeable It is recommended that all domestic rabbit owners be reminded to vaccinate their rabbits prior to the release of RHDV1 K5 and/or ensure their animals’ vaccinations are up-to-date. There is no treatment or cure for rabbit haemorrhagic disease (RHD). We have Just like any other pet animal, rabbits are also susceptible to a range of diseases and illnesses throughout their life. It is a virus that is spread by rabbit to rabbit contact or by vectors. On the 24th of February, 2016 we were notified that the new strain of Neither study (this study, nor Cox et al. , 2022). Calicivirus is species specific and as such does not pose a risk to humans and other non-rabbit species. Rabbit calicivirus has been active in Australia since late 1995 and New Zealand since mid-1997, with variable effects on rabbit populations. In most susceptible adult rabbits the disease progresses rapidly from fever and lethargy to death within 48–72 hours of infection. , 2005b). Rabbit hemorrhagic disease is an extremely contagious and often fatal viral disease of domesticated and wild rabbits. The nonpathogenic RCV Wirblich C, et al. Rabbit hemorrhagic disease (RHD), also known as rabbit calicivirus disease, is an acute, highly contagious, and often fatal disease of rabbits caused by rabbit hemorrhagic disease virus The LBG is facilitating its annual summer Calicivirus RHDV1-K5 (K5) Release Program with participating landholders across its operational area, including the northern localities of the Donnybrook-Balingup Shire, Shires of Capel and Dardanup and the City of Bunbury. Rabbit haemorrhagic disease virus (RHDV, or GI. Antibodies that For many caliciviruses, feasible cell culture systems are missing. ) are unaffected. 1. Disease Caused Rabbit calicivirus and human health. RHDV2 was detected in wild rabbit samples collected in 2017. This is also true for the calicivirus rabbit hemorrhagic disease virus (RHDV), a member of the genus Lagovirus, that is the causative agent for rabbit hemorrhagic disease, a fatal illness of domestic and wild rabbits (2,3).

Rabbits at K5 release sites may have had some existing immunity to K5 due to previously having been exposed to other RHDV variants (inc. The national release of a Korean strain of Rabbit Haemorrhagic Disease Virus, known as RHDV1 K5 took place during the first week of March 2017. J Virol, 70, 8614-23. Antigenic variants of RHDV known as RHDVa strains are reportedly replacing RHDV strains in other parts of the world, and Australia is currently Environmental Persistence of Rabbit Hemorrhagic Disease Calicivirus • Rabbit Hemorrhagic Disease (RHD) calicivirus is spread by oral, nasal and parenteral transmission • The virus is present in urine and feces from infected rabbits, thus contaminated bedding can be a source of infection • Contaminated foods can be a source of infection. ARRFA believes that none of these outcomes Strains of myxomatosis and rabbit calicivirus (rabbit hemorrhagic disease [RHD]) have been released in Australia for rabbit control. Rabbit haemorrhagic disease virus (RHDV), introduced into in Australia and New Zealand as a biological-control agent for wild rabbits, is least efficacious in cool humid areas where a non-pathogenic calicivirus (RCV-A1) also circulates. Signs: sudden death with bleeding from nose/mouth or more vague and slower onset clinical signs. Keywords: rabbits, calicivirus, myxomatosis, RCD, RHDV, pest o The release occurrred at a time and under conditions that did not have the greatest possible impact on the rabbit population. The etiological agent, the rabbit haemorrhagic disease virus (RHDV), belongs to the Lagovirus genus in the Caliciviridae family On 2 July 1997 the Deputy Director-General of Agriculture declined the application to import and release RCD. However, in another human pathogenic calicivirus, the sapovirus (SV), NS6 pro NS7 pol is the only protein detected in a cell-free system (Oka et al. The disease was characterised by haemorrhages around the body. Calicivirus, or rabbit haemorrhagic disease virus (RHDV), is a virus that typically causes a rapidly fatal disease in European rabbits. DoctorYakMaster15. 1984; Abrantes et al. RHDV was deliberately released in Australia and New Zealand as a biologic control for European rabbits and is now established in the wild in these countries . (Rabbit Calicivirus), and RCD (Rabbit Calicivirus Disease) depending on which country you’re in. RHDV causes a generalized infection in rabbits that is characterized by necrosis of the liver, disseminated intravascular coagulation, In vitro cultivation of caliciviruses indicates that these pathogens have been emerging periodically from ocean sources for 65 years . Treatment: supportive. It is not known to effect humans or other animals, including cottontails and jackrabbits. Rabbit Calicivirus, also known as Rabbit Haemorrhagic Disease Virus (RHDV), is a viral disease first released in Australia in 1996, in an effort to control feral rabbits. The endemic non-pathogenic rabbit calicivirus in Australia (RCV-A1) can provide some • selected for release in Australia because it can better overcome the protective effects of the non-pathogenic calicivirus (RCV-A1) which occurs in the feral rabbit populations in both Australia and New Zealand • may assist in overcoming resistance of rabbits to the old virus Dana still wasn’t sure if releasing the rabbit calicivirus was a good idea, but she couldn’t let Melynda’s claims go unchallenged. , 2020; Disease Images. o The consultation process was necessarily compromised, with certain groups claiming hardship as a result. A similar virus occurs in To the Editor: A disease outbreak in a Michigan rabbitry led Bergin et al. We quantified the impact of the release of rabbit haemorrhagic disease virus K5 (RHDV K5, hereafter K5) and pindone (2‐pivalyl‐1,3‐indandione) baiting at 13 sites within Cudlee Creek fire scar in the Adelaide Hills, South Australia. Characteristics of the Visited Farms. To those who love rabbits it’s been a tough few years. Signs include fever, restlessness, lethargy, and poor appetite with bleeding from the nose and/or blood on the floor where rabbits are housed. Often infected rabbits will show no signs and die suddenly. The ‘classic’ Czech strain of Rabbit Haemorrhagic Disease Virus released in 1995. Fortier Department of Animal Log in Join. It was first reported in China in 1984 and soon after in other countries in Asia and Europe and in Mexico. The 2017 myxomatosis outbreakSee also information in the comments regarding home disinfection. , 2012). ARRFA believes that none of these outcomes A new strain of the rabbit calicivirus has been confirmed in a single wild rabbit found on a Marlborough farm. The “K5″ strain of the Rabbit Haemorrhagic Disease Virus (RHDV1) which is used specifically for the control of rabbits, specifically affects rabbits. This is also true for the calicivirus rabbit hemorrhagic disease virus (RHDV), a member of the genus Lagovirus, that is the causative agent for rabbit hemorrhagic disease, a fatal illness of domestic and wild rabbits (2, 3). This is the first time in 20 years that a new rabbit biocontrol agent has been released into Australia. Rabbit hemorrhagic disease virus (RHDV), a member of the genus Lagovirus in the family Caliciviridae, is used effectively as a biocontrol agent in Australia to reduce the significant environmental and economic impact of feral European rabbit (Oryctolagus cuniculus) populations []. Due to the high level of pathogenicity and species specificity of the In 1995, the calicivirus, or rabbit haemorrhagic disease virus (RHDV), was accidentally released in Aus-tralia when it was being under consideration as a new potential biological control agent, following the devastating impact of its release in Europe. It was illegally introduced into New Zealand, where it is now used similarly—as a biological control. 21 11:50 AM By Kim Cooney - Comment(s) How the rabbit calicivirus RHDV2 strain was ‘accidentally’ released from a government lab in SA 1995. Figure 1 shows the number of farms (1714 in total) Environment Canterbury announced the results of its release programme for the new rabbit haemorrhagic virus disease strain, RHDV1 K5. Genetic map of the calicivirus rabbit hemorrhagic disease virus as deduced from in vitro translation studies. The virus has been released into bushland reserves and national parks in the northern Sydney region, from Parramatta to Pittwater4. Precautions for rabbit owners. ) and hares (Lepus spp. I understand that the Rabbit Calicivirus was deliberately released into the environment of the south-western part of the Lake Macquarie State Conservation Area in 2005, but I am unaware of subsequent attempts to control rabbit Rabbit hemorrhagic disease virus (RHDV) is a calicivirus in the genus Lagovirus causing acute hepatic necrosis in European rabbits (Oryctolagus cuniculus), leading to disseminated intravascular coagulation and death in > 90% of susceptible animals (). The virus affects rabbits and the Rabbit haemorrhagic disease or rabbit hemorrhagic disease (RHD) is a highly contagious disease that mainly affects rabbits of the Oryctolagus cuniculus species but has also been confirmed to affect various species of cottontails (Sylvilagus spp. The strain – called RHDV2 – is widespread in Europe and Australia, but this is the first time it has been found in New Zealand, says MPI response manager John Brightwell. The virus was released at 110 sites in Western Australia. Rabbit calicivirus in Australia - information provided by the Australian Veterinary Association There are a number of RHDV strains pre Australia; RHDV 1 - Original virus released in 1995 RHDV1A - Variant of type 1 isolated in Sydney in 2014 Rabbit haemorrhagic disease virus (RHDV) 1 K5 will be released nationally in the first week of March 2017. Rabbit hemorrhagic disease virus (RHDV) is a highly pathogenic member of the family Caliciviridae within the genus Lagovirus (). cunicuusi) are highly susceptible; cottontail rabbits (Sylvilagus floridanus) and hares (Lepus spp. Google Scholar. J Virol 1996;70:7974–7983. Canberra, Australia: Department of Primary Industries and Energy, Australian Government (Released under the Official Information Act). Rabbit haemorrhagic disease (RHD) was first described in China among domestic rabbits (Oryctolagus cuniculus) imported from East Germany in 1984 []. This paper discusses the Australian Rabbit Calicivirus Disease (RCD) Program, an attempt at the biological control of wild rabbits, as an example of how technoscience in `Mode-2 society' works. Aotearoa, New Zealand has three confirmed strains of the virus and there is no guaranteed cure. Specifically, viruses within the GI.
