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 Cats,Dogs,Horses,RabiesHere are updated versions of the US rabies maps from yesterday’s post, with the addition of some more data. Pennsylvania’s looking more biohazardous now but that’s because we got a lot more data for that state. If we get more data from other areas, the maps will be updated accordingly.… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Horses,Rabies,VaccinationWe track a few different diseases, both for research and for general education, including rabies. The maps below provide an overview of rabies in dogs, cats and horses in the US in 2017. It’s not a complete representation of cases, since we don’t have access to everyone’s surveillance data. It’s compiled through monitoring various reports… Continue Reading
By Scott Weese on Posted in Dogs,RabiesA dog attacks someone and is shot by police. Unfortunate, but sadly it happens. The sheriff’s investigator notifies the county health department, which says the dog needs to be tested for rabies. Good. That sometimes gets missed. The investigator then tells the owner that he has to remove the dog’s head or he’ll face a charge… Continue Reading
By Scott Weese on Posted in Dogs,RabiesIf a dog bites a person or another animal, there are two ways to make sure that the bite couldn’t have resulted in transmission of rabies virus: Euthanize the dog and test the brain for rabies. Ensure the dog is still neurologically normal 10 days later (if this is the case, then the dog could not have… Continue Reading
By Scott Weese on Posted in Dogs,RabiesWhile waiting in line to check-in for a flight in Orlando, a JetBlue passenger was bitten by a dog. This raises lots of issues and questions, and for the bitten individual, she’s dealing with a pretty nasty bite and also the potential need for rabies post-exposure prophylaxis. She was bitten while checking in, so it… Continue Reading
By Scott Weese on Posted in RabiesAs expected, rabies continues to be an issue in Ontario following the emergence of raccoon rabies in the Hamilton area in late 2015, and a separate emergence of fox rabies northwest of there around the same time. Hopefully raccoon rabies will be eradicated, as it was the first time it entered the province (1999-2005), but… Continue Reading
By Scott Weese on Posted in RabiesA couple times in the past few weeks, I’ve had questions along the lines of “Bat rabies isn’t really a big deal, is it?” and “How common in rabies in bats? It’s not really that common, right?” We don’t know how common rabies is in the bat population, since most testing of bats is sporadic… Continue Reading
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
