A recent study suggests that the H9N2 bird flu strain, often considered minor, has adapted to human cells, raising concerns about its potential to spark a human pandemic.
Although cases of person-to-person transmission have not been reported yet, scientists are worried about the spread of this and other bird viruses, particularly given the attention focused on the H5N1 avian influenza virus in recent years.
The researchers say more surveillance of the virus is needed.
The study's findings emphasize the importance of monitoring the H9N2 virus to prevent a potential pandemic.
