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 Brooklyn, NY. Whether that’s a small contained cluster or the sign of a new large outbreak (especially considering the number of dogs in that area) remains to be seen.

The Canadian situation has shown what can happen with good surveillance and infection control (or, I guess, despite that, with some good luck). Regardless of the result, our flu outbreaks have been confined and as far as we can tell, canine influenza has been eradicated in the country, since we have seen no new cases for a period well beyond the incubation and shedding period for this virus.
