Scientists identify mutation that could facilitate H5N1 'bird flu' virus infection and potential transmission in humans
Avian influenza viruses typically require several mutations to adapt and spread among humans, but what happens when just one change can increase the risk of becoming a pandemic virus? A recent study reveals that a single mutation in the H5N1 'bird flu' virus that has recently infected dairy cows in the U.S. could enhance the virus' ability to attach to human cells, potentially increasing the risk of passing from person to person. The findings highlight the need to monitor H5N1's evolution.
