More Michigan herds found to be infected and Florida wildlife

This article is announcing that Michigan has begun to find more infected herds.  They needed to have implement contact tracing like California and they likely would have found all the infected herds by now (they were the second state to have infected workers).  This just means that the virus continues to circulate in dairy herds in Michigan, and if they want to stop the spread they are going to have to start contact tracing or testing all the herds in the state.
This article is also reporting that the H5N1 virus has been found to be infecting dolphins in Florida.  These samples were collected in January before the outbreak in Texas.  The USDA has classified the dolphin virus as EA H5N1 (east asian H5N1), and did not designate it as the recombinant dairy virus that they classify as EA/AM H5N1.  So the dolphin infection was the same virus that has been killing sea mammals in South America and may not be the same recombinant as the dairy virus infecting sand killing mammals around dairy farms.
