H5N1 only needs a single mutation to readily latch on to human cells found in the upper airway.
The study authors focused on altering a protein that contains the binding site that allows the virus to latch onto host cell receptors and kick-start infection.
Previous studies have shown that several influenza mutations are important in human receptor binding.
A teenager in Canada was hospitalized in critical condition from bird flu with unknown exposure.
Genetic sequencing showed a strain of H5N1 that was similar to one circulating in Canadian poultry.
Scientists don’t know if either mutation was responsible for the teenager’s severe condition.
