Guest guest Posted January 22, 2002 Report Share Posted January 22, 2002 Urgent news about spread of Rabbit Hemorrhagic Disease in the USA **************************************************************************** * Rabbit Information Service has received information from the USA Coalition against RHD (RHD is Rabbit Hemorrhagic Disease) about the latest New York outbreak of rabbit hemorrhagic disease (USA). According to a spokesperson from the " USA Coalition against RHD " , the New York outbreak of RHD at a wildlife center may have come from frozen rabbit meat. There are concerns RHD infected frozen rabbit meat could be sitting in USA supermarkets. No further response has been received from APHIS concerning the possible source of the New York RHD outbreak being frozen rabbit meat. Imported frozen rabbit meat was the source of a widespread outbreak of RHD in Mexico in the 1980's which was eradicated due to a huge effort by Mexican authorities and the USDA. Many thousands of rabbits died in the Mexican outbreak. Read about the 1989 RHD outbreak in Mexico at http://www.iinet.net.au/~rabbit/jarr.htm Rabbit Hemorrhagic Disease is a fatal disease of rabbits that has no cure. According to USA authorities " Adult rabbits seem to be most commonly affected with VHD, but it can also be seen in young rabbits older than 8 weeks. There appears to be a wide range of morbidity (those rabbits being affected). It can be as low as 30% or as high as 80%. Of rabbits affected the mortality reaches 95-100%. In other words, if the rabbit gets VHD, it will almost always die. The incubation period is very short, apparently 24-72 hours. The route of entry of the virus into the host has not been completely determined, but it apparently can invade the respiratory tract , the digestive tract or come in through scratches or abrasions in the skin. Experimentally, the virus has produced the disease when introduced orally, intramuscularly or by intraperitonial injection. It has been suggested that the virus can be transmitted by aerosols, direct contact, equipment, in the meat or by-products and possibly by insects or rodents. There seem to be three forms of the disease: the peracute form is when all that is seen is a dead rabbit in the cage; the acute form of the disease is when the rabbit shows depression, goes off feed, and has difficulty in breathing. This rabbit dies in one to two days and exhibits incoordination, shaking and evidence of pain prior to death. It may also show a mucus blood stained nasal discharge. When the rabbits are first observed, the rectal temperature may increase 2-3 degrees F (normal rectal temperature 103 degrees F). The third form of the disease seems to be much milder. The rabbits appear sick but then recover and are immune to reinfection. " The USA does not allow the use of the RHD vaccine and RHD survives on clothing for over 60 days and can survive freezing and temperature extremes. British authorities say RHD is suspected of being transmitted by dust particles, on lorry tyres, by birds or by people who have been in contact with RHD. Australian authorities say " biting and sucking insects " can spread RHD disease (fleas, flies and mosquitoes). RHD may survive on inanimate objects. RHD has killed millions of rabbits throughout Europe, Asia, Australia and New Zealand. Please be vigilant and protect your pet rabbits. Precautionary measures include showering and changing clothes if you have been in contact with the RHD. Apparently, the current RHD vaccine used to protect pet rabbits in Australia, NZ and Europe is based on " seed stock " of virus grown in sheds of live rabbits. This is an inhumane method of producing a vaccine base (many pet rabbits are deliberately infected and killed to reproduce the virus for the vaccine).
