No new NM dairy cow avian flu cases confirmed in weeks

It’s still unknown how many cows and poultry have been affected.

BY: DANIELLE PROKOP - MAY 15, 2024 12:59 PM

...
New Mexico is still counting eight herds with confirmed positives of Highly Pathogenic Avian Influenza, all in Curry County, and no presumptive positive cases, state agriculture officials said Monday.

“We do not have exact numbers of cows affected in each herd, but the average has been about 10%,” state veterinarian Samantha Uhrig said in a written response to questions.

The state is unaware of any cow deaths that are directly attributed to avian flu, she added.

Uhrig said the state will not name infected dairies and will only identify them at the county level.

New Mexico health officials have no plans to implement further wastewater testing for H5N1, said State Public Health Veterinarian Erin Phipps with the Department of Health.

New Mexico has not been asked to be involved in any wastewater-testing plans for avian flu at this point, Phipps said, “although I am aware of many conversations happening amongst many different entities about wastewater.”

USDA Adds House Mouse To Mammals Affected by H5N1




#18,101

Last week the USDA added domestic cats to their list of mammalian infections, and in today's update, they've added 11 infections of a new species Mus musculus (the common house mouse), all from a single county (Roosevelt) in New Mexico.



While it is not surprising that mice are susceptible to H5N1, given past laboratory experiments (see NIH Assessing avian influenza in dairy milk), this is the first time they've been placed on the USDA's list.

There are no details provided on where these mice were collected, or if they we're symptomatic, or even dead. While it seems likely these were barn mice at a dairy farm, it would be nice to have those details.

In any event, the number of mammalian spillovers reported to the USDA continue to grow, and now sits a 259, spread across 22 species.



Given the sparse surveillance, and the difficulty in locating and testing sick or dead animals in the wild, this is likely a huge under-counting of affected mammals.

This may explain the cats that are not affiliated with Dairy farms, getting infected with H5N1.

USDA Adds An Additional 19 Mice To HPAI Detections in Mammals List (n=66)






#18,133


Two weeks ago the USDA added a new species - the common house mouse (Mus musculus) - to their list of mammals with HPAI H5N1. On June 4th they posted the first 11 detections, all in Roosevelt County, New Mexico. Last Tuesday they added 36 more.

While no details were provided as to how or where these mice were sampled, last week a WOAH WAHIS dashboard carried a report stating that `Wild house mice (Mus musculus) and wild red fox (Vulpes vulpes) collected from an HPAI affected poultry premises.'

For the 3rd Tuesday running the USDA has updated their list by adding 19 more mice, all presumably from the same location (see list below).




Among the unknowns, we don't know if all of these mice were found dead, or if some (or all) were live-trapped. We don't know how widespread they might be on the farm, or whether some were captured outside of the poultry houses.

We don't even know if this is the same B3.13 clade that has affected cattle, or if they display any genetic changes of note.

The lack of detail from the USDA is particularly frustrating, as this is an unusually large (and growing) number of detections in a mammalian species that - until two weeks ago - had never been listed.

More detailed answers are eagerly awaited.
