Yoshi Kawaoka: These strains belong to different clades, or subgroups, within the H5N1 family, which means that their genetic makeup is slightly different. Some emerged in the previous outbreaks ...

SACRAMENTO, the United States -- Scientists are sounding the alarm about a concerning genetic mutation of the H5N1 bird flu ...

Essentially, this means that while 36% of the H5N1 genetic code has diverged, or mutated, two thirds has not – which implies this unchanged genetic coding is serving an important function.

meaning it carries genetic material from multiple H5N1 lineages. One of these lineages has been traced to wild birds in Bangladesh, while another is linked to a strain circulating in South Korea.

This strain of bird flu, also known as H5N1, is not entirely new. It's been detected in a variety of bird populations since January 2022, and in March of last year, it was found in dairy cows for ...
