ProMED翻訳情報(326回) ~カナダで発生したアライグマの狂犬病事例~

On [2 Jun 2014], a raccoon from St Stephen, New Brunswick, tested positive for the raccoon variant of rabies. The raccoon rabies variant  was last detected in New Brunswick in May 2002, in this same general geographic area. Prior to this June 2014 occurrence in a raccoon, the last case of rabies in this province was detected in Fredericton in November 2013 in a big brown bat (in this case, the virus was a bat variant of rabies virus and not the raccoon variant).

2014年6月2日、ニューブランズウィックのセントステファンのアライグマが狂犬病のアライグマ変異株に陽性と診断された。アライグマ狂犬病変異株は2002年5月にニューブランズウィックの地理的にほぼ同一の地域で最後に検出された。2014年6月のアライグマでの発生以前の、この州における最後の狂犬病の症例は2013年11月、フレデリクトンにおいてBig Brown Bat(和名オオクビワコウモリ)で検出された。(この症例では、ウイルスはコウモリ変異株であり、アライグマ変異株ではない)


In this recent raccoon case, a family in St Stephen had returned home on the evening of Thu May 29 2014, to find their 2 dogs excitedly circling around something in the yard. The object of attention was a raccoon, which evidently was moving abnormally slowly and was circling. The raccoon was killed and buried. Afterward, the dogs shared popsicles with the family’s 2 young children. It was not known if the dogs had had contact with the raccoon, but if they had been bitten, it is likely that they would have licked any wounds they incurred and so could have been exposed to the raccoon’s saliva. The raccoon was dug up and its brain was extracted by the New Brunswick Provincial Veterinary Laboratory and sent to the Canadian Food Inspection Agency Rabies Laboratory in Ottawa for testing. Test results were completed on [2 Jun 2014] and variant typing was completed on [3 Jun 2014].



Post-exposure treatment has been started on the 2 children. Both dogs had been vaccinated previously against rabies, although one dog was overdue for revaccination. Both dogs were given booster vaccinations for rabies and have been put under quarantine. The family also has an indoor-outdoor cat which had never been vaccinated against rabies. The cat was vaccinated and also is being quarantined. 4 of the immediate neighbours also have dogs, and there is a school nearby.



In 2001, the New Brunswick government launched a successful trap-vaccinate-release program to control the raccoon variant of rabies, targeting wild raccoons, skunks, foxes, and feral cats(defined as cats with no collars or identification). No decision has yet been made on a general response to this newly-detected rabid raccoon, apart from the immediate public and human health actions described above. The New Brunswick government has not yet established a provincial protocol for responses to suspected cases of animal rabies to replace protocol previously followed by the CFIA, which terminated its local responses to potential rabies cases as of 1 Apr 2014.    [byline: Jim Goltz]



[Rabid raccoons may lose their fear of humans and other animals and they may become slower and stuporose. They present profuse salivation, indiscriminate biting, and odd vocalizations. It can be confused withdistemper. It is very important to keep all dogs and cats in the area up to date with both rabies and distemper vaccination. ]
