Bird flu, also known as the highly pathogenic H5N1 avian influenza, has been making the rounds in the United States over the last year and appears to be resurging again, according to officials with the Centers for Disease Control and Prevention.

Bird flu is a disease caused by avian influenza A viruses, according to the CDC. The virus mostly spreads between birds and dairy cows, but there have been 67 human cases of bird flu nationwide and one death tied to the infection since 2024, CDC records show.

As concerns about bird flu rise in the U.S., a new study is warning about the virus' ability to mutate in humans. Dr. Amish Adalja, an infectious disease physician, joins "The Daily Report" to discuss the study and how concerned people should be about the disease.
