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
Update: Canine influenza, US and Canada (2018 October)
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…
Update: Canine influenza, Ontario (October 20)
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…
Ontario hits 10 000 dRIT rabies tests since 2015
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…
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…
Update: Canine influenza, Ontario (April 23)
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…
Update: Canine influenza, Ontario (April 9)
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…
Update: Canine influenza, USA (April 4)
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…
Update: Canine influenza, Ontario (April 2)
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.
- 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
Update: Canine influenza, Ontario (March 23)
- 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.
- Good progress has been made. Few new cases have been identified over the past two weeks.
- One problematic aspect
