With any new, changing or inadequately investigated infectious disease, we need to understand scope of the problem, and that includes the range of species that can be infected. The ongoing human monkeypox outbreak has raised concern about spillback of monkeypox virus into animals from humans since we don’t know much about susceptible animal species.
A
Things have been pretty quite regarding monkeypox in domestic animals lately. Whether that’s because human-to-animal infection is truly rare, and human case numbers are dropping, or whether it’s because there’s not enough surveillance in domestic animals that have been exposed to the virus isn’t clear. I suspect it’s a combination of the two. Our surveillance
As H5N1 avian flu ramps up again across Canada with the fall wild bird migration, we’re likely going to see more situations where more unique populations of captive birds are affected, beyond the usual large or small poultry flocks. The CFIA’s standard response to highly pathogenic avian flu (like the current H5N1 strain) is “
Since rabbit hemorrhagic disease virus type II (RHDV2) made its first incursion into Canada, and again more recently with the first detection of this virus in Ontario, there’s been a lot of interest in vaccination of rabbits (rabbits and hares are the only species known to be affected). Effective vaccines are available for this
If you follow zoonotic diseases, you might look at the title of this post and think “What is he rehashing now? We already know Salmonella is common in reptiles, and contact with reptiles is a major risk factor for salmonellosis in people.”
In large part, you’d be right. Not a lot has changed
We already have an update on the Michigan dog disease outbreak that I wrote about yesterday which has attracted a lot of attention.
An update (August 24) from the Michigan State Veterinarian indicates this appears to be an outbreak of parvovirus. I’m not overly surprised. As I wrote yesterday:
An outbreak of our typical canine

’ve been holding off writing about this, hoping for more details, but my inbox has been flooded with questions about it so I figured I’d get the ball rolling. There’s been a bit of a media frenzy about an apparent outbreak of severe disease in dogs in northern Michigan.
What do we know?
As an Associate Editor for Emerging Infectious Diseases and as a frequent peer reviewer for other journals, I see lots of paper that report finding a “new” virus. These can be a challenge to interpret, because advances in technology now let us find things we’ve never been able to find before. The problem is, we
Now that human-dog transmission of monkeypox has been identified, there’s a lot more interest in what to do about animals that have been exposed to infected people. As more people get monkeypox, more animals will be exposed. We want to reduce the risk of animals getting infected (and possibly then infecting more people), while
I’ll start this off with “don’t freak out, overhype this, or be paranoid about your dog.” (I’ll probably end with that too).
A recent report in Lancet (Seang et al. 2022) describes a pretty solid case of suspected monkeypox virus (MPXV) transmission from people to a dog. The dog, an otherwise healthy Italian
