Because the virus causes severe tissue necrosis and inflammation, secondary bacterial infections happen often during influenza outbreaks.
What are Secondary infections?
There are several ways that a primary infection can increase susceptibility to disease, leading to a secondary infection.
A secondary infection is one that develops during or following the treatment for a primary illness. It has been determined that a secondary bacterial infection affects up to 75% of people who acquire pneumonia after contracting the flu.
