The American Veterinary Medical Association has issued information about new strains of canine respiratory coronavirus and canine parvovirus. Both are highly contagiou, and there are no vaccines available for either one. The risk of dogs contracting either of these new strains increases when large numbers of dogs are housed together in close confinement, such as in kennels or at dog shows, so breeders and exhibitors need to be aware of the dangers.
According to the AVMA, the canine respiratory coronavirus (CRCoV) can cause an acute respiratory infection, and is part of the complex of viruses and bacteria associated with canine infectious respiratory disease (CIRD) or "kennel cough." Highly contagious, CRCoV is spread by direct contact with infected dogs and by coughing and sneezing. It can also contaminate kennel surfaces, food and water bowls, collars and leashes, and the hands and clothing of people who handle infected dogs. More information about CRCoV is available on the AVMA web site at http://www.avma.org/animal_health/canine_coronavirus_faq.asp
Canine Parvovirus Type 2c (CPV-2c) has recently emerged in the United States. Like other, related parvoviruses, it causes loss of appetite, vomiting and diarrhea, and dehydration, and can lead to death. Because the antigens of CPV-2c are slightly different than those of other parvoviruses, existing vaccines may not be as effective in preventing CPV-2c, and some parvo tests will not detect the presence of the new strain.
Dogs with vomiting or diarrhea or dogs who have been exposed to ill dogs should not be taken to kennels, show grounds, dog parks, or other areas where they will come into contact with other dogs. People who are in contact with sick or exposed dogs should avoid handling other dogs, or at least should wash their hands and change their clothes before doing so. All parvoviruses are very hardy, are resistant to many disenfectants, and can survive in the environment for long periods, so preventative measures are especially important.
