California, Washington and Oregon are still calling the dairy virus "avian influenza" but the infection hasn't been spread from birds to cattle since it was first detected. The poultry flocks that have been infected by the virus had all been infected by nearby dairies in all cases where that determination could be made. The poultry flocks are quickly depopulated, so the back infection to dairies hasn't been noted. Dairies are not depopulated, and continue to infect other farms.
Influenza A in swine and Humans is avian influenza, but we call it swine flu or just the flu in humans.
The use of "avian influenza" for the dairy virus is allowing Washington and Oregon to ignore the fact that they likely have infected dairies in their states, and they refuse to identify those infected herds. Poultry flocks have always been infected by nearby dairies, so when a poultry flock goes down with the dairy virus there are infected dairies in the area. It was found in Michigan and Texas (both states started getting infected poultry flocks after the diary virus was detected) that around 7% of the workers on infected dairies also worked on poultry farms. More worked at other dairies because most dairies do not maintain full time staff. Contact tracing was never implemented to identify all the infected herds. California implemented contact tracing and have identified around half the total known infected herds in just the last month.
https://www.cidrap.umn.edu/avian-influenza-bird-flu/more-human-avian-flu-cases-washington-state-californiaThis article claims that the number of confirmed infected herds in California is now up to 186 (388 total herds). Sample submission numbers indicate that over 200 samples have already been sent in for verification by the end of last week. Once a herd has tested positive a sample is sent in for verification. California understands that their commercial poultry flocks have been infected by the dairies.
Continuing to call H5N1 genotype B3.13 avian influenza is just allowing states like Washington and Oregon to deny having infected dairy herds, so they do not have to do anything to identify the infected herds, and reduce human infections. It is just contributing to the CDC current plan to allow the virus to evolve into the next pandemic before trying to contain it. The stupid existing plan is to wait until the virus starts to be observed spreading in the human population before stepping in and trying to contain the infection. California has high population density and two busy international airports.
We no longer call swine flu nor human influenza virus "avian influeza" so why keep calling the dairy influenza "avian influenza"? It now has 10 to 15% mortality among infected cattle in California.
They are only testing workers with symptoms, but they know that a lot of asymptomatic dairy cattle were shedding virus. They just have never implemented testing asymptomatic dairy workers. Nasal swabs could be negative, but the milk samples could have high levels of virus. They know for human infections that nasal swabs were negative but eye swabs were positive.
CIDRAP has been one of the most up to date news source on the dairy infection, but Minnesota never implemented contact tracing when their dairy herds were found to be infected, and they have not reported new dairy infections for quite some time (the first infections were confirmed in early June in Minnesota) even though multiple commercial poultry flocks continued to go down with the dairy virus. They may be keeping track of what others are doing, but they are not doing much to clear the infection from their state. Minnesota seems to be pretending that they do not have the issue.
