I’m lazy so I’ll use the blog to answer a question that I’m getting a few times a day.  Today’s question: how to disinfect a veterinary clinic if there is a concern about canine influenza?

The good news is that influenza viruses are pretty wimpy. They’re enveloped viruses, meaning they are covered by a

  • 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

Active canine influenza cases are still known to be present in two regions in Ontario.

  • 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

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

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

The table below has the latest H3N2 canine influenza numbers from IDEXX Laboratories. Some of the highlights include:

  • Numbers continue to increase. Northern California and Nevada are the hotbeds, with northern CA cases increasing to 343 and Nevada 151. As always, these are just the tested cases, and they presumably represent a small minority of

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.

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
