H5N1 new cases

They are claiming that sequence results indicate that the Arizona dairy D1.1 infection is not related to the D1.1 dairy infection in Nevada. This would mean that avian influenza has transferred to cattle 3 independent events.  Texas (B3.13), Nevada (D1.1), and now Arizona (D1.1)
Two more cats in Oregon were infected by contaminated raw pet food made in Washington state.  They identified H5N1 in the cats that needed to be put down, and the pet food that both cats had eaten (the same brand). They now have a consumer alert on Wild Coast Raw, pet food.  A bunch of commercial and backyard poultry flocks have been hit by H5N1 in 4 states, but like the cats they aren't stating what genotype they were infected with.  Two large layer farms went down in Indiana.  Over 57 million birds affected since just Nov. 2024, 162 million since 2022.
It should be noted that they only detected the Nevada and Arizona infections due to the recent USDA testing program.  The claim is that the herds were not showing symptoms until after they turned out positive.  They would have never been tested under the old volunteer testing program.

California is claiming that 281 of the 745 infected herds have cleared the virus already.  This likely means that the virus likely has infected most of the herds in other states and they are likely fully recovered by the time that the USDA is finally testing them.  9 states were identified to have produced virus positive milk samples by the FDA, but they would not test their dairy herds back in May 2024.  3 of those states eventually claimed at least one infected herd, but the others remained in denial.  The virus likely burned through all the herds in those states by now, and the herds would have recovered months ago.  The D1.1 dairy infections is the second wave for these states.  Nevada had an older case of dairy virus infection, but they only claimed one infected herd, now they have half a dozen herds infected with D1.1, and none detected with B3.13.  The D1.1 virus likely spread through the Nevada herds the same way that the B3.13 virus spread (cattle and people shared between farms).  Now we even have evidence (3 infected veterinarians) that vets could have taken the virus from farm to farm, and not even known that they were infected.
