By most indications, the avian influenza outbreak that has washed over U.S. farms is at an ebb. Experts don’t seem hopeful, however, that the problem has taken care of itself.

The infection was detected in a single sheep in Yorkshire on Monday and, while bird flu does not spread easily to people, the UKHSA has ranked the H5N1 strain as an "emerging infection" in England.

New research suggests that past exposure to seasonal flu viruses may help protect people from severe illness caused by the H5N1 avian flu virus. Scientists at the Perelman School of Medicine at the University of Pennsylvania found that older adults who were exposed to flu viruses circulating before 1968 were more likely to have antibodies that recognize H5N1.

Gov. Tim Walz and state leaders on Wednesday urged new strategies to protect Minnesotans and agricultural producers from H5N1, an influenza strain that has spread rapidly in the U.S. among wild and domestic birds and dairy farms over the past three years.

Minnesota Gov. Tim Walz says there is a "unified front" in the state's fight against bird flu, which was recently detected in a Stearns County dairy herd.

Minnesota leaders, including Gov. Tim Walz, provided insight into how they plan to handle a bird flu outbreak in Minnesota that is helping drive egg prices up.
