Scientists find a mutation in bird flu virus H5N1 that could enable human-to-human transmission.

A recent study published in Science suggests that a single mutation in the H5N1 bird flu virus could enable it to bind more effectively to human cells, potentially leading to human-to-human transmission. This mutation, identified in the hemagglutinin protein, has not yet been observed in real-world cases but has been tested in lab settings. The H5N1 virus has already caused human infections in the U.S., and experts are concerned about its potential to evolve into a pandemic strain.
