A dairy herd in Minnesota that was confirmed to be infected in July 2024, but has likely been clear of the virus for several months has been infected again.  They do not know what genotype of H5N1 is infecting the herd.  Another herd in California also was confirmed to be positive.
They still have not disclosed the genotypes of the recent Idaho and California infections.  At this time both the B3.13 and the D1.1 virus has been found in Dairy herds (D1.1 in Arizona and Nevada)
