It discusses that influenza is a virus that causes an estimated 36,000 deaths per year in the US. While the symptoms of influenza are similar to other illnesses, diagnosis can only be confirmed via testing. It also discusses influenza epidemics throughout history like the deadly 1918 Spanish Flu pandemic.
