It can be downloaded directly here or be found… Continue Reading

Updated Equine West Nile Virus and EEE Maps

Posted in Horses
The title says it all. Here are the most recent maps from WormsAndGermsMap showing equine cases of West Nile virus and Eastern Equine Encephalitis (EEE) virus infection. As with any surveillance, the maps only capture a percentage of the true number of cases, but looking at the geographic distribution and trends in date-of-onset can still be informative. West… Continue Reading

Equine Arbovirus Update

Posted in Horses, Other diseases
Arboviruses (ARthropod-BOrne viruses) are viruses that are spread by insects, often mosquitoes. As I’ve written about recently, mosquito biology and differences in reservoir species mean that mosquito-borne viruses can have quite different patterns of distribution and spread. As is common, the occurrence of West Nile virus infection in horses tends to ramp up in late… Continue Reading

Fatal Horse-Associated Streptococcus zooepidemicus Infection

Posted in Horses
A recent report in MMWR describes a pair of Streptococcus equi subsp. zooepidemicus infections in people.  The cases are noteworthy because this bacterium doesn’t often cause human infections, and because one of the infected people died. More commonly referred to simply as Strep zoo, this bacterium is very commonly found in perfectly healthy horses, although… Continue Reading

Eastern Equine Encephalitis Season in Full Swing

Posted in Horses, Other diseases, Vaccination
‘Tis the season for mosquitoes, so ‘tis the season for some nasty vector-borne diseases. Few are worse that Eastern Equine Encephalitis (EEE), a viral infection that causes typically fatal disease in horses, and less commonly other species, including people. Cases tend to start mid-summer and peak late summer to fall, depending on the mosquito dynamics… Continue Reading

Clean Hands Save Lives: Horsey-Style

Posted in Horses
Infection control isn’t rocket science. Wash your hands, don’t eat that, keep your finger out of your nose… things you learned in kindergarten go a long way to preventing infections. The basic nature of the core infection control concepts is also a barrier – hand washing isn’t fancy, new or associated with some fancy machine. (There… Continue Reading

Worms and Germs Map Update

Posted in Cats, Dogs, Horses, Parasites, Rabies
A 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

Mapping Zoonotic Disease Emergence Risk

Posted in Birds, Cats, Dogs, Horses, Other animals, Other diseases, Pocket pets, Reptiles
Predicting the future is a dodgy proposition at the best of times. It’s particularly hard with infectious diseases, which tend not to behave as expected. Yet, it’s important to plan surveillance, education and response. One approach is to assess where certain types of problems are more likely to develop. That can help direct resources (time,… Continue Reading

Equine Biosecurity Standards

Posted in Horses
The Canadian Food Inspection Agency (which, despite the name, deals with broader animal issues as well, not just those related to food), in conjunction with a variety of partners, has developed a National Farm and Facility Level Biosecurity Standard for the Equine Sector. It’s a comprehensive overview of best practices for infectious disease control in the… Continue Reading

10 More Rabid Raccoons in Hamilton

Posted in Cats, Dogs, Horses, Rabies
It 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

Rabies in a horse

Posted in Horses, Rabies, Vaccination
A 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

Get Smart About Antibiotics Week

Posted in Cats, Dogs, Horses, Miscellaneous, Other animals
Since their discovery in the mid-1900s (which really wasn’t that long ago in the grand scheme of things), antibiotics have revolutionized human medicine, veterinary medicine and even food production.  They save lives and prevent illness, helping to make both people and animals healthier, happier and more efficient at what they do.  But if we want… Continue Reading

Equine anaplasmosis: Ontario

Posted in Horses
Another Ontario issue to report: this one is in a horse. Recently, a case of anaplasmosis was identified in a horse in Eastern Ontario. People in some places may say “so what?” The reason it’s noteworthy is that anaplasmosis has historically been a very rare disease in Ontario. It’s a infection caused by the bacterium Anaplasma… Continue Reading

Tick ID card

Posted in Cats, Dogs, Horses
Knowing your ticks is important. Certain ticks are able to transmit certain diseases, so knowing what to look for, on yourself and your animals, is useful. To help with that, Wellington Dufferin Guelph Public Health has released a quick-reference Tick ID Card.  When folded in half, it’s about the size of a business card, so… Continue Reading

Ontario eastern equine encephalitis update

Posted in Horses
During today’s Canadian Equine Infectious Disease Surveillance call, Dr. Alison Moore from the Ontario Ministry of Agriculture Food and Rural Affairs gave an update on equine infectious neurological disease cases in the province. Prominent amongst those disease is eastern equine encephalitis (EEE). This very mosquito-borne viral infection is fortunately pretty rare in horses and is… Continue Reading

Equine infectious disease podcasts

Posted in Horses
This summer, we started a monthly Canadian Equine Infectious Disease Surveillance teleconference series to provide quick periodic updates on various infectious disease issues and outbreaks to/from provincial, territorial and federal regulatory animal health officials, academia, practicing veterinarians and industry partners. Recordings of some of the calls are now available on the Equine Canada website.  … Continue Reading

New Ontario rabies website

Posted in Cats, Dogs, Horses, Other animals, Rabies, Vaccination
The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has launched its new (and long-awaited) rabies website.  The site includes a section for the public which is an ideal resource for clients, and a section for veterinarians with detailed information about reporting, risk assessment, sample submission and testing, and post-exposure management (for companion animals and… Continue Reading

Equine infectious anemia in Canada

Posted in Horses
A recent cluster of equine infectious anemia (EIA) cases in Saskatchewan highlights the personal side of EIA control. EIA is a serious insect-borne viral disease of horses that can cause illness ranging from mild to fatal. Some horses recover uneventfully but are then potential sources of the virus for others, and disease can build up slowly and silently… Continue Reading

New USEF equine vaccination requirements

Posted in Horses, Vaccination
Mandatory vaccination for horses entering shows, other events and sales has been a surprisingly contentious issue for years. Some groups have required equine influenza vaccination for a long time, and it’s an accepted measure. Attempts to mandate vaccination for some other groups or events have often been met with resistance, even when those attempts were… Continue Reading

West Nile virus in Ontario

Posted in Horses, Vaccination
The season has arrived. Right on schedule, the first case of West Nile virus (WNV)  infection in an Ontario horse has been identified, prompting an advisory from the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA). The affected horse was from Sudbury, Ontario, and was euthanized because of progressive and severe neurological disease. It… Continue Reading

Equine strangles persistence

Posted in Horses
This week, a horse show in Halifax (UK) was cancelled because of some local cases of strangles (Streptococcus equi subsp equi infection). We can debate whether that was prudent or overkill (or whether measures could have been put in place to reduce the risk and make it manageable), but it highlights the concerns that accompany… Continue Reading
