Some variant strains can further infect mammals, including humans (3,18,28). Therefore, research on H9 AIV is of economic importance and public health significance.
Webwith AIV is often very low compared with specimens from seasonal influenza cases [36]. Therefore, a highly sensitive detection system is needed to diagnose cases of human infection with AIV. An evaluation of the H9 rRT-PCR assay using artificially reconstituted clinical samples showed that the assay could detect a small viral load (Cp > 30) of H9N2
