The viral genome sequences suggest that the teenager in Vancouver has an H5N1 avian influenza virus with mutations that might improve its ability to infect human airways.
Immunologist Scott Hensley reassures that there's no immediate cause for panic despite the concerning developments regarding the avian influenza virus's mutations and potential human impact.
Public health officer Bonnie Henry emphasizes the mystery of the infection's source, noting the adolescent had no apparent links to poultry farms and no signs of virus in pets.
The recent findings indicate that the H5N1 strain in the teenager has three key mutations; two may enhance its ability to infect human cells and replicate effectively.
