By Scott Weese on Posted in Other animals,RabiesHere’s the latest map of the terrestrial rabies cases in southwestern Ontario. Raccoon-variant cases still centre on the Hamilton area. It was never assumed that this particular outbreak would be eliminated quickly, given the case numbers seen in the first several months and the additional challenges of trying to control the spread of the virus in… Continue Reading
By Scott Weese on Posted in Horses,Rabies,VaccinationIf a horse comes into the hospital at this time of year and has some difficulty standing, incoordination and mild fever, the first thing on my list of likely causes is probably equine herpesvirus type I (EHV-1) infection. Next would be West Nile virus encephalitis. However, we consider all sudden onset neurological disease cases in… Continue Reading
By Scott Weese on Posted in Parasites,Rabies1) Pick up baby raccoons and take them away Rarely does this end well. It’s illegal in many areas (including Ontario). Raccoons don’t do well long-term in households for various reasons (their curious and destructive nature being a big one). And, they are potential sources of a number of zoonotic diseases (rabies being a big one but not… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationTwo rabid dogs have been identified in Whapmagoostui, a Cree community in a remote region of northern Quebec. Rabies is very rare in dogs in Canada, and in recent years, much of the concern has revolved around rabies in dogs from northern communities. Rabies is endemic in Arctic foxes, and dogs can be infected from… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationEvery few weeks I get a call or an email about travel-associated rabies exposure concerns. It’s usually from someone traveling to southeast Asia or India who has been bitten by a stray dog. Most of the time, it’s an unvaccinated person and the dog isn’t available for monitoring or testing. Since rabies is endemic in… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other animals,Rabies,VaccinationThis month, Public Health Ontario released a new Rabies Guidance Document for Healthcare Providers. It’s nothing particularly new but a good review of the recommended response to rabies exposure from various animal species, something that’s unfortunately often messed up or made more complicated than necessary. It includes some nice flowcharts, such as the one below. The full… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationIn many countries, rabies is a disease we’re concerned about but one that is rarely seen in domestic animals and is exceptionally rare in people. It’s easy to forget that people in other areas are confronted with a risk of rabies on a regular basis. Canine rabies is a major problem in Africa, leading to… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationThere tends to be confusion about what happens when an animal bites or is bitten, and rabies is being considered. Most of the confusion revolves around how long an animal is quarantined or observed. Yet, it’s actually pretty straightforward if you think about why quarantine/observation is being performed and some basics about the virus and… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Other animals,Rabies,VaccinationThe 2016 Compendium of Animal Rabies Prevention and Control has been released by the US’s National Association of State Public Health Veterinarians (NASPHV). This version has updates in a few different areas, such as some changes to recommendations for dogs, cats and ferrets that have potentially been exposed to rabies. It can be downloaded directly here or be found… Continue Reading
By Scott Weese on Posted in Other animals,Rabies,VaccinationEvery few days, it seems, I get an email or call that goes something like “I was just bitten by [insert various mammals here]. Do I need to worry about rabies or do anything?” The answer’s pretty similar every time. While the relative risk posed by different animal species in different geographic regions varies, you… Continue Reading
By Scott Weese on Posted in RabiesWhen a bat is found in a household, the response can be quite variable. Many public health units may consider it a potential rabies exposure if the bat was in the house overnight, on the assumption that a bite could have occurred without being noticed (I have personal experience with that). Based on the large… Continue Reading
By Maureen Anderson on Posted in RabiesIt has been just over 1 year since the discovery of the first rabid raccoon in Ontario in over a decade, and the first rabid wildlife in the Hamilton area in over two decades. Since then well over 4500 abnormal or “found dead” wildlife have been tested, and 253 animals carrying raccoon-variant rabies have been… Continue Reading
By Maureen Anderson on Posted in Rabies,VaccinationRaccoon-variant rabies cases around the Hamilton area continue to trickle in slowly but steadily each week. The total number of cases is now up to 187 since December 2015, with 132 cases in raccoons and 53 in skunks. The remaining two cases were in less common – but not altogether unexpected – species: a fox… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Parasites,RabiesA few years ago, we launched WormsAndGermsMap to help track certain emerging and endemic diseases. Data are entered by participating veterinary clinics, surveillance programs and the WormsAndGerms team. While we certainly can’t capture every case, we do collect some interesting information about the presence of certain diseases. Using the “Report Filter” bar on the left, you can… Continue Reading
By Scott Weese on Posted in RabiesWhen raccoon rabies re-emerged in Ontario last fall, one of the big questions was “where did it come from?” It had been eradicated from the province and control measures were in place at the borders to reduce the risk of re-introduction. It was assumed that a rabid raccoon hitched a ride across the border from… Continue Reading
By Scott Weese on Posted in Dogs,Rabies,VaccinationI’ve written a lot about the issues of dog importation and the diseases that can sometimes “come along for the ride”. However, high risk movement doesn’t need to be international. Any movement from a high risk area can be a concern. A recent article in Canadian Communicable Disease Report (Curry et al. 2016) addresses the issue of… Continue Reading
By Scott Weese on Posted in RabiesRaccoon rabies continues to be a concern in the Hamilton, Ontario area. After being eradicated in Ontario for years over a decade, raccoon rabies snuck back into the province late last year. Intensive surveillance and baiting efforts by the Ministry of Natural Resources and Forestry (MNRF) continue. Almost half a million oral rabies vaccine baits… Continue Reading
By Scott Weese on Posted in Dogs,RabiesA Florida couple is suing their neighbour in an attempt to get the neighbour’s dog euthanized for rabies testing. The dog attacked the couple’s beagle, and the wife was bitten while intervening (as was her sister). Because there was a bite, it’s important to consider the potential for rabies exposure and take appropriate actions. But… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other animals,Rabies,VaccinationSuccess can breed apathy. Apathy can lead to bad decisions. That’s a common problem with vaccinations. People lose sight of why we vaccinate. Growing up during a time when many major pathogens have been controlled by vaccines, it’s easy to forget about how bad those diseases are. Whether it’s resurgence in measles in people because… Continue Reading
By Scott Weese on Posted in RabiesThe latest edition of CDC’s Morbidity and Mortality Weekly Reports describes a case of rabies in a Missouri man. Rabies is rare in people in the US, but it remains an ever-present risk because the virus circulates in various wildlife species. (This case seems to have been from 2014, but they missed some proofreading since… Continue Reading
By Maureen Anderson on Posted in Cats,Dogs,Horses,RabiesIt seems to be a bit of a slow month for zoonoses. Finally getting some cold weather here in Ontario certainly helps keep many bugs at bay (and people indoors). Nonetheless, rabies continues to keep us hopping. The Ministry of Natural Resources and Forestry (MNRF) is continuing with its surveillance efforts around the cluster of… Continue Reading
By Scott Weese on Posted in Horses,Rabies,VaccinationA horse in South Carolina was recently diagnosed with rabies. While rabies is common in some animal species in some regions, it’s a pretty rare disease in horses, so it’s a noteworthy event. This case has a couple of important takeaway messages. Rabies can be sneaky. Rabies (especially in horses and cattle) isn’t always obvious… Continue Reading
By Scott Weese on Posted in Other animals,Rabies,VaccinationIn a rather unusual development, a calf in Ellice Ward, Ontario has been diagnosed with rabies. It’s the first case of rabies in any animal species in Perth County since 2012, and looking at the Canadian Food Inspection Agency surveillance records, it’s the first rabid bovine in Ontario since 2011. Rabies has been in the… Continue Reading
By Maureen Anderson on Posted in Cats,Dogs,Rabies,VaccinationThe incursion of raccoon rabies in the Hamilton ON area reached a total of 10 confirmed cases as of last week. A map of the current MNRF control zone is available on the OMAFRA website. This is the area where the Ministry of Natural Resources and Forestry (MNRF) has spread oral rabies vaccine (ORV) baits… Continue Reading
