Influenza (flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness. Serious outcomes of flu infection can result in hospitalization or death. Some people, such as older people, young children, and people with certain health conditions, are at high risk of serious flu complications (CDC, 2018).
According to a Walgreens study from September 2011, influenza was responsible for 100 million lost workdays during the 2010-2011 flu season. That’s $7 billion in lost wages; two-thirds of the missed workdays were employer-paid sick time. The flu sliced more than $10 billion off company productivity.
The most effective way to prevent acquiring the flu is by getting the flu vaccination.
