Potential Human Pandemic from Bird Flu Strain
A bird flu virus, H9N2, has the potential to spark a human pandemic, despite typically causing minor disease in birds.
Experiments suggest that H9N2 has adapted to human cells, however, person-to-person transmission cases have not been reported yet.

Scientists are concerned about the spread of other bird viruses, such as H9N2, in addition to the well-known H5N1 avian influenza virus.
