update dairy influenza

This is a post that I tried to send 5/4, but no new posts loaded since 4/30.
I've been on the road for most of April, but in terms of the H5N1 dairy epidemic the USDA and CDC seem to be continuing to downplay the situation and continue to refuse to say if the continuing infections of cattle are the D1 (wild bird) or B3.13 (dairy) genotype.

According to the GISAID phylogeny the infection of the Nevada dairy worker with the D1 genotype (supposedly infected by infected dairy cattle) and the Wyoming patient that had to be hospitalized with the D1 infection got infected by a virus that is the same lineage as the D1 genotype that infected some of the Washington poultry workers back in October 2024.  These were the poultry workers that were detected 10/23 and not with the first group detected 10/09.  The 10/23 group were likely the group that was detected because they went to Oregon and tested positive.  It looks like some infected Washington poultry workers went to Wyoming and Nevada and infected animals there so that the Wyoming patient (02/11/2025) and the Nevada dairy worker (02/04/2025) could be infected.  The D1 infection was established in Nevada before the Wyoming patient was infected with the same lineage, so the D1 virus may have gone from Washington to Nevada, and then to Wyoming and Arizona.  Washington did not restrict poultry worker movements even though they knew that some of them were infected.  Nevada wasn't restricting worker movements even though they knew that dairy workers were getting infected.  No contact tracing was attempted.
Nothing about the relationship between the Washington poultry worker strain and the Wyoming and Nevada infections has been announced because the CDC and USDA refuse to do the epidemiological analysis of the samples that they obtain, and the USDA continues to put out useless data and continue to refuse to state where the samples came from except that they came from the USA.  The human infections can be tracked because the CDC does supply the location information with the sequence, but they have consistently refused to do the epidemiological analysis.  They do not want to do contact tracing nor detect the human to animal and human to human infections that have likely been occurring.
Idaho is having a major second round of infection of their herds.  They were one of the first states to have infected herds, but they stopped testing their herds early on and just let the infection run through the state.  They are not stating if this round is the D1 virus or continues to be the B3.13 genotype.  The initial Idaho infection were infected by a lineage that came from Texas, but the infection detected by contact tracing from California half a year later was infected by the California lineage.  This lineage is significantly different from the Texas lineages, and it is likely that those herds were infected by the California cattle, and not the other way around as California was claiming.  The California strain may be infecting all the recent Idaho herds or it could be the D1 genotype from Arizona and Nevada.
Since I went on the road, herds in Arizona, Idaho, and California have continued to be confirmed to be infected, but they are not saying what genotype is responsible for the infections.
