The H9N2 subtype avian influenza virus (H9N2 AIV), which has been in circulation for two decades, has become the predominant subtype in China, attracting considerable attention due to human infections and the contribution of internal genes to H5N1 and H7N9 influenza viruses. Mul...
The H9N2 outbreaks in Ghana highlight the importance of performing a differential diagnosis and an in-depth characterization of emerging viruses. In addition, the detection of a potentially zoonotic subtype, such as the H9N2, in a region where highly pathogenic avian influenza H5Nx is currently ...
Following the outbreak of H5N1 "bird flu" in Hong Kong in 1997, the isolation of H9N2 subtype viruses from patients in southern China and Hong Kong SAR once again raised the spectre of a possible influenza pandemic. H9N2 viruses have recently been responsible for disease in poultry in various...
Since the 1990s, influenza A viruses of the H9N2 subtype have been causing infections in the poultry population around the globe. This influenza subtype is widely circulating in poultry and human cases of AI H9N2 have been sporadically reported in countries where this virus is endemic in domestic...
(PCR) techniques and real-timePCR, which are rapid assays, have been developed for the detection and subtype identification of virus in clinical samples. Commercial antigen-detectionimmunoassayshave also been used for fast diagnosis. These tests detect any influenza A virus and are generally...
