The Centers for Disease Control and Prevention has issued a warning regarding H5N1 bird flu, suggesting it may be more transmissible between humans than previously believed. Samples collected from a patient in Louisiana showed concerning mutations, although no evidence of transmission to others has been found. Experts advise caution and vigilance, but stress there is no need for panic. Further testing and vaccine development are underway to address the situation, with the CDC emphasizing that the overall risk to the public remains low.
