Summary:
- Researchers have identified a single mutation in the H5N1 influenza virus that could make it easier for the virus to infect humans.
- The mutation alters the hemagglutinin (HA) surface protein, which the virus uses to attach to and infect human cells.
- This finding suggests that the H5N1 virus, also known as avian flu, may be evolving to become more transmissible to humans, highlighting the importance of continued surveillance and research to monitor potential pandemic threats.
