By Scott Weese on Posted in Dogs,VaccinationCanine influenza is (once again) causing big problems in some parts of the western US. Following reports of influenza outbreaks in animal shelters in Oakland, California, it’s apparent that it has spread within California shelters and to an Oregon shelter. It is also affecting pet dogs in various cities in California. It’s not surprising that these… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationDuring today’s Public Health Agency of Canada webinar, part of a new webinar series on zoonoses and adaptation in a changing world, Chelsea Raybern from the Kansas State Deptartment of Health and Environment provided a report about rabies in a dog that was imported into Kansas from Egypt in 2019. The dog had been in… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationEffective tomorrow, the US Centers for Disease Control and Prevention (CDC) has suspended importation of dogs to the US that: are from Egypt, or originated in Egypt and have been in another country for less than 6 months. This is being done because of multiple cases of rabies in imported dogs specifically from Egypt over… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationRabies is “almost always” transmitted by bites and “almost invariably” fatal once disease develops in a person or animal. We use a lot of these kinds of disclaimers with infectious diseases, which can be frustrating, but it’s necessary because exceptional (strange) things occasionally occur. A report in an upcoming edition of Emerging Infectious Diseases (Zhao… Continue Reading
By Scott Weese on Posted in Deworming,Dogs,ParasitesNothing has changed about Echinococcus multilocularis (the fox tapeworm) in the past couple of months, but my phone is ringing off the hook following another round of media reports about this parasite. Here’s a recap of the issues: Echinococcus multilocularis is a small tapeworm normally found in the intestinal tract of wild canids (e.g. coyotes, foxes)… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationRabies vaccination of dogs is legally required in many areas. In most of those, it must be given by a veterinarian, unlike some other vaccines that can be purchased from a veterinarian or supplier and administered by owners. Why does a veterinarian have to administer rabies vaccines? There are a few reasons. One is that… Continue Reading
By Scott Weese on Posted in Dogs,Other diseases,VaccinationI’ve had a few discussions with people over the past week about geographic variation in disease risk. It’s a great subject because it’s an important and often overlooked issue. Whether it’s animals being imported, animals moving with their owners, animals accompanying owners on vacation or animals being moved between regions within the county, movement between… Continue Reading
By Scott Weese on Posted in Deworming,Dogs,ParasitesEchinococcus multilocularis (EM) is an important zoonotic tapeworm. The situation with this parasite in Canada (and probably the US) is unclear and evolving. It’s increasingly clear that EM is present in a high percentage of wild canids (e.g. coyotes, foxes) in some regions. What this means for human health isn’t clear yet. This tiny tapeworm lives… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationWe often talk about rabies in the context of high GDP countries, focusing on wildlife rabies and exposure during travel. However, in many parts of the world, exposure to canine rabies is an ever-present risk, and there can be substantial barriers to getting proper post-exposure prophylaxis (PEP) when needed. That’s part of the reason tens… Continue Reading
By Scott Weese on Posted in Dogs,Other diseases,VaccinationHere’s a report from Cornell University’s Animal Health Diagnostic Center, describing importation of a canine distemper strain that hasn’t been found before in North America: 02/05/2019: (N. America) In early October of 2018, a 12-week old “Sheltie” arrived from Korea. Approximately 12 days later, the dog began with a cough and lethargy with blood work indicating… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationIt’s easy to get complacent about rabies, even when you live in an endemic region. While we have ample bat rabies, Arctic fox rabies and raccoon rabies in Ontario, spillover into domestic animals is relatively rare. Success can breed complacency, though. When control measures work, it’s easy to forget why they are so important. That’s… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Rabies,VaccinationHere are some more leftover questions from the talk I did a talk recently for Third Age Learning in Guelph: As West Nile virus seems to be spreading, is there a vaccine becoming available for the general population? Probably not, but that’s just a guess. While it should be possible to make an effective human… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Rabies,VaccinationBefore the emails start rolling in… yes, it’s from a satire site. See Dr. Sarah Boston (veterinary cancer surgeon extraordinaire)’s take on how veterinarians are misleading people into protecting people. EXPOSED – Vaccination of Pets Found to be Part of Larger Plot to Prevent Rabies in Humans… Continue Reading
By Scott Weese on Posted in Deworming,Dogs,ParasitesEchinococcus multilocularis, a small tapeworm with a big name, is causing big concerns in Ontario, an area that was until recently considered free of this parasite. This tapeworm is normally found in the intestinal tract of wild canids (e.g. coyotes, foxes) and can also infect dogs. That itself isn’t a problem, since the intestinal form… Continue Reading
By Scott Weese on Posted in Cats,Deworming,VaccinationThe indoor vs outdoor cat debate never seems to end. Some decry outdoor cats as the world’s most destructive “invasive species.” Some say that outdoor cats do what outdoor cats (and any other carnivores) do… they hunt to eat. Cats kill large numbers of birds every year. So do lots of other things. In an… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Other animals,Rabies,VaccinationAs is typical for this time of year, the annual US rabies report has been published in the Journal of the American Veterinary Medical Association (Ma et al, 2018). Here are some highlights: 4454 rabid animals were identified across the country. This is certainly a marked underestimate of the actual number since most rabid animals… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationNo, we haven’t changed to a cooking blog, I’m talking about bites of the canine variety. I can’t think of any specific data that would show it, but I wonder whether bites are more common around the holidays, with disrupted schedules and more visitors (and a potential midnight intruder in a red suit). The rabies-related… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other animals,Rabies,VaccinationHuman deaths from rabies are common in some developing countries (where tens of thousands die from canine rabies every year) but rare in developed countries. It’s an almost invariably fatal disease, but at the same time it’s almost completely preventable because of the quality of vaccines and post-exposure prophylaxis available. Getting those treatments to the… Continue Reading
By Scott Weese on Posted in Horses,Other diseases,VaccinationBeing an equine vet in some parts of Australia (namely Queensland) is scary… to the point that people are leaving equine practice or refusing to treat certain cases. That’s because of Hendra virus, a bat-associated virus that infects horses and which can spill over into people. It hasn’t infected many people, but it is most… Continue Reading
By Scott Weese on Posted in Dogs,VaccinationCanine influenza continues to cause problems in Ontario. The central Ontario (Bracebridge, Gravenhurst, Orillia) clusters continue to be monitored, with new positives that were expected based on known contact with infected dogs. Whether these clusters have been contained (or are containable) remains to be seen. Testing and contact tracing continues. As mentioned previously, there was… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationThe World Health Organization has issued new rabies vaccination and post-exposure prophylaxis recommendations. Here are some of the highlights: Post-exposure prophylaxis People who have not been previously vaccinated against rabies should receive immunoglobulin (antibody) promptly, followed by a series of rabies vaccines. Immunoglobulin can be given after vaccination has started, if logistics require that; however, it… Continue Reading
By Scott Weese on Posted in Dogs,VaccinationThe recent H3N2 canine influenza cluster in Ontario is hopefully still contained. Some infected dogs continue to shed the virus, but a good thing about flu is that there’s no long-term carrier state. Dogs will typically shed the virus for a couple of weeks, but then it should be gone. Accordingly, if the affected dogs… Continue Reading
By Scott Weese on Posted in Dogs,VaccinationA Fremont, California dog park was temporarily closed in response to concerns about canine leptospirosis after 4 reports of dogs contracting the disease, potentially associated with exposure at the park. It’s always hard to determine the source of exposure with lepto, but a park is certainly possible. We don’t understand a lot about how and where… Continue Reading
By Scott Weese on Posted in Dogs,VaccinationNot surprisingly, “should my dog be vaccinated against flu?” has been a very common question over the past few days. Here’s my take on vaccination of Canadian dogs, with the assumption that the recent H3N2 flu cluster in southwestern Ontario has been contained (something that is likely but is still to be determined). Who should… Continue Reading
