This ‘minor’ bird flu strain has potential to spark human pandemic

Potential Human Pandemic from H9N2 Bird Flu Strain

A recent study suggests that the H9N2 bird flu strain, often considered minor, has adapted to human cells, posing a potential risk for a human pandemic.

Although experiments indicate this adaptation, there have been no reported cases of person-to-person transmission thus far.

The researchers emphasize that more surveillance of the H9N2 virus is necessary.

The focus has primarily been on the avian influenza virus H5N1, but scientists are now expressing concern over the spread of other bird viruses, including H9N2.
