Persistent predominance of the Victoria lineage of influenza B virus during COVID-19 epidemic in Nanchang, China.

The sentinel hospital-based influenza-like illness (ILI) surveillance network was established in China since the 2009 H1N1 pandemic. This network plays important roles in monitoring influenza virus variation and identifying novel respiratory pathogens. In this study, we characterized the pathogen spectrum pattern (PSP) of ILI based on three sentinel hospitals and analyzed the significant change of PSP during the COVID-19 epidemic.
