Update: Canine influenza, Ontario (October 30)

Posted in Dogs
Things have been quiet over the past few days. That’s good news (but always makes me a bit antsy, because I want to be sure it’s because there are no new cases vs we’re just not finding them). Documented infections have been confined to one region, with the exception of a dog that travelled out… Continue Reading

Update: Canine influenza, Ontario (October 25)

Posted in Dogs
As expected, a few more cases have been identified in the most recent cluster of canine influenza virus (CIV) identified in Ontario. So far, there are about 20 confirmed or suspected cases. To date, we’re still only finding cases that have a link to another infected dog or facility. That’s good news. If we start… Continue Reading

Update: Canine influenza, US and Canada (2018 October)

Posted in Dogs
While we’re still working on sorting out and containing our latest Canadian outbreak of H3N2 canine influenza, we can look to the south to see the problems this virus is still causing. Flu is still active in a variety of locations in the US. The numbers reported are presumably a marked under-estimate, since it’s based… Continue Reading

Update: Canine influenza, Ontario (October 20)

Posted in Dogs
More cases of H3N2 canine influenza have been identified in the province since the virus was re-introduction to central Ontario in the last week. That’s not surprising, since the start of any outbreak investigation is dedicated to figuring out the extent of the problem. Cases identified in the first few days or week reflect things… Continue Reading

Ontario hits 10 000 dRIT rabies tests since 2015

Posted in Other animals, Rabies
Today’s post comes from Rachel Gagnon, Rabies Science Transfer Specialist with the Ontario Ministry of Natural Resources and Forestry (MNRF), highlighting some of the amazing work being done in Ontario in the ongoing battle against wildlife rabies. Ontario’s rabies control program is a world leader when it comes to controlling and eliminating rabies. The MNRF… Continue Reading

Update: Canine influenza, US and Canada (May 18)

The latest IDEXX Laboratories maps and case list are below. Canine flu continues to cause problems in some parts of the US, and is spreading in some states. California and Nevada have had active flu for a few months, but it may be abating. New clusters are popping up in other areas, most notably in… Continue Reading

Update: Canine influenza, Ontario (April 23)

Posted in Dogs
I’ve been holding off saying “it’s gone” but based on all the information we have at the moment, there’s no evidence of ongoing canine flu activity in Canada, at least for now. No new cases have been identified in a few weeks and we are now beyond the 28-day recommended quarantine period for all of… Continue Reading

Update: Canine influenza, Ontario (April 9)

Posted in Dogs
No news is good news… at least hopefully. The past week was quite encouraging. No new cases of canine influenza were identified in Ontario. A couple of “inconclusive” results were obtained from dogs in the Northumberland cluster that were previously positive. I approach these as essentially “weak positives,” because it means the test detected viral… Continue Reading

Update: Canine influenza, USA (April 4)

Posted in Dogs
I’m slowly catching up so here are last week’s data from IDEXX Laboratories on the canine flu situation in the US. The two main areas of concern remain California and Nevada. The number of new cases dropped quite a bit from the previous week. That’s encouraging, but it can be hard to interpret passive surveillance… Continue Reading

Update: Canine influenza, Ontario (April 2)

Posted in Dogs
I’ve been slow to provide an update, partly because I’ve been sick (not with canine flu) and partly because there’s fortunately less to report. Muskoka We are still testing but it’s pretty low yield. One challenge is the baseline upper respiratory disease activity in the area. There are various viruses and bacteria that cause flu-like… Continue Reading

Update: Canine influenza, Ontario (March 23)

Posted in Dogs
Windsor-Essex: Things have been quiet there for a while and this seems to be a nice success story. The two flu clusters that were active in January were contained and nothing new has been seen. Muskoka: Good progress has been made. Few new cases have been identified over the past two weeks. One problematic aspect… Continue Reading

Turtles and Salmonella

Posted in Other animals, Reptiles, Salmonella
Taking a break from canine flu and going back to an old favorite… Salmonella and reptiles. CDC has released their final update on a multistate outbreak of Salmonella Agbeni infections associated with contact with pet turtles. Turtles are very well known as high risk animals for transmitting Salmonella. Even healthy turtles often carry Salmonella and… Continue Reading

Update: Canine influenza, US and Canada (March 13)

Posted in Dogs
United States (data courtesy of IDEXX Laboratories) Canine flu continues to cause problems in the US, particularly the west coast. Northern California (471 cases) and Nevada (207 cases) are the hotbeds. As ever, since these data are from diagnostic laboratory submissions, they probably represent the minority of cases (since most dogs with respiratory tract disease… Continue Reading

Update: Canine influenza, Ontario (March 10)

Posted in Dogs
Active canine influenza cases are still known to be present in two regions in Ontario. Muskoka A small number of dogs from the initial cluster of cases in the Orillia/Bracebridge/Gravenhurst region are still shedding the virus, as expected given this virus can be shed by some dogs for a few weeks. The dogs that made… Continue Reading

Update: Canine influenza, Ontario (March 8)

Posted in Dogs, Vaccination
Canine 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

New multistate salmonella outbreak

Posted in Other animals, Salmonella
I’m giving my brain a short break from canine flu, so here’s an interesting report about a multistate US outbreak of salmonellosis linked to… no, not turtles… no, not baby poultry… but guinea pigs. While guinea pigs have been associated with a few different zoonotic diseases, they’re a pretty benign pet species overall. Yet, our… Continue Reading

Update: Canine influenza, Ontario (March 5)

The third cluster of canine flu in Ontario is a problem. While the first two, in the Windsor-Essex area, were relatively small and have been contained, the recent, ongoing central Ontario cluster is larger and more widespread. There are over 20 confirmed cases to date. However, it is very likely that the actual number is… Continue Reading

Canine influenza in Canada: New cluster

Posted in Dogs
While we had hoped that control of the two recent clusters of H3N2 canine influenza in Windsor-Essex, Ontario, meant that the province was again free of that virus, another cluster of infections has been identified, this time in Orillia, Ontario. Investigation is ongoing so the number of infected dogs is currently unclear, but as always,… Continue Reading

Canine flu outbreak update: US

Posted in Dogs
While we have hopefully been able to contain our two recent H3N2 canine influenza clusters in Canada (more on that later), this virus continues to spread in some parts of the US, particularly Northern California and Nevada. Since the last update from IDEXX Laboratories on February 2nd, they have identified another 164 cases in the… Continue Reading

US canine flu update

Posted in Dogs
Canine flu has been a hot topic around here, but it’s a bigger deal in the US where the range of the disease is much larger. IDEXX Laboratories has released an update on their canine flu testing results. California has been getting a lot of attention over the past couple of weeks, but extensive flu… Continue Reading

Update: Petland puppy Campylobacter outbreak (Jan 29)

Posted in Dogs, Other diseases
I was talking to someone today about their new puppy, their puppy’s diarrhea and (take a guess) the fact that they developed diarrhea shortly thereafter. Odds are pretty good that puppy and owner both have campylobacteriosis. While this infection isn’t related to the ongoing US multistate Campylobacter outbreak linked to puppies from Petland stores, it’s… Continue Reading

Infections from backyard poultry

Posted in Birds, Salmonella
Hardly a week goes by that I don’t get a question (or a dozen) about backyard poultry. As more cities consider or enact laws allowing urban poultry, the debates about and around this issue increase. It’s also becoming a big business, with ample options for people to buy chicken coops (or high end chicken condos),… Continue Reading

Update: Petland puppy Campylobacter outbreak (Oct 5)

Posted in Dogs
Here’s some follow up information from the recent (and probably ongoing) outbreak of Campylobacter infections linked to puppies purchased at Petland stores in the US: 55 infected people have been identified now. That’s probably just a fraction of the people who were truly infected, because of the number of steps that need to happen to… Continue Reading
