Finding H5N1 avian influenza in mice in the US has caused a lot of angst amongst some – some angst is warranted, but some of it is overblown. That’s not because H5N1 isn’t an issue, or that more species being involved isn’t relevant, but because there are bigger issues to address. Adding yet another species
Raccoons, Raccoon Roundworms and Swimming Pools
Here’s a question I get surprisingly often.
I found a dead raccoon (or raccoon poop) in my pool and I’m freaking out about raccoon roundworms. What should I do?
The raccoon roundworm, Baylisascaris procyonis, is certainly a parasite of concern, but it’s also one that often leads to over-reaction and panic. While it can
Update: H5N1 Avian Flu in Cats in Poland (June 29), and Musing About Sources
Information continues to trickle in about the situation with H5N1 avian influenza in cats in Poland. It’s mainly been updating the number of confirmed infected cats, with 16 cats in 3 cities being the latest number I’ve seen. It’s also now reported that some of the cats are primarily indoor (house) cats.
Numbers are part
Update: H5N1 Avian Flu Spillover in Cats, Poland (June 27)
Yesterday, I discussed a situation where avian flu was suspected in the deaths of a reasonably large number of cats in Poland. “We need more information” was a big part of that, and as of today a few new pieces of the puzzle have come to light.
H5N5 Avian Influenza in Mammals, Canada
Yes, I’m prone to making typos. No, this title isn’t one of them.
While we’re in the midst of an unprecedented international outbreak of H5N1 avian flu (with ongoing spillover into mammals), there’s a new kid on the block: H5N5 influenza. I think recent reports of H5N5 were glossed over by some who didn’t realize
H5N1 Avian Flu and Animal Shelters
As the unprecedented global H5N1 avian flu outbreak continues (with no real end in sight), and as we get the spring mix of migrating birds, mingling bird populations, more active wildlife and a pending crop of baby wild critters, concerns about spillover infections from birds to mammals are on the rise.
The current H5N1 influenza
Rabbit Hemorrhagic Disease in Ontario, Canada
Addendum: OMAFRA has now issued their notification, along with advisories for vets and rabbit owners.
Rabbit hemorrhagic disease has been identified in a group of pet rabbits in Lambton County, Ontario. This is a bit of a “surprising, but not surprising” scenario, as this highly contagious virus of rabbits is already present
H5N1 Avian Influenza in Foxes: Ontario
H5N1 influenza was recently found in two wild fox kits in St. Marys, Ontario. It’s a pretty noteworthy event given the scope of the current H5N1 highly pathogenic avian influenza (HPAI) outbreak across Canada, and the fact this is the first identification of H5N1 influenza in wild mammals in Ontario. The fox
Should We Vaccinate Animals Against SARS-CoV-2?
Concerns about the animal aspects of the COVID-19 pandemic continue to come in waves. Most of the time they are ignored or dismissed, but there are also periodic flurries of attention and (often over-) reaction. Lately, questions about vaccination of animals against SARS-CoV-2 follow have been on the rise.
Should domestic and wild animals be
Are “Deer Strains” of SARS-CoV-2 Emerging?
One thing we’ve been watching for with SARS-CoV-2 in animals is whether we will see establishment of “animal” variants. Humans have done an effective job of infecting a wide variety of animal species with this primarily-human virus. Fortunately, thus far these infections usually die out rapidly in that animal or group of animals (mink being
