More than a decade ago, researchers at the University of Wisconsin, Madison, studying avian flu, or H5N1, warned that only a few mutations in the virus would enable it to transmit to mammals. Today, H5N1 has infected 51 dairy cattle herds across nine states. Just yesterday, a second human case of H5N1 infection was detected in Michigan.
