Scientists have identified mutations that could allow H5N1 bird flu to bind to human respiratory receptors, increasing the risk of a pandemic.

Experts warn that these adaptations provide the virus more chances to jump to humans, necessitating urgent global surveillance. Preemptive vaccine development is now considered vital to prevent a potential global health crisis.
