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.
The prevalence of influenza and related secondary bacterial illnesses can be decreased by using infection prevention techniques. The best method to prevent this is to be vaccinated against the flu every year and practice proper hygiene, like frequent, thorough handwashing.
