The CDC reported that the bird flu virus likely mutated in a Louisiana patient. The mutations may allow the virus to better bind to receptors in the airways of humans, raising concerns but not alarm. The virus has caused sporadic mild illnesses in the U.S., mostly in farm workers. The Louisiana patient, hospitalized in critical condition, had respiratory symptoms after contact with sick birds. There has been no known transmission of the virus to others. Scientists are monitoring the mutations closely for potential future pandemics, emphasizing the need for continued vigilance. The risk to the general public remains low for now.
