Research progress on the mechanism of secondary bacterial infection of influenza virus

A secondary bacterial infection of the influenza virus in the lungs is a key cause of exacerbation and death. The pathogenesis is characterized by complex interactions between co-infecting pathogens and the host, leading to the destruction of the physical barrier of the airways and the dysregulation of the immune response. This article will review the progress of the mechanism of secondary bacterial infection of influenza virus and provide strategies for preventing the co-infection of influenza virus and bacteria.
