The flu isn’t just the flu—it can bring serious risks

A bout of flu may make you feel awful, but more important, it can also put you at risk for dangerous flu-related complications. The flu can lead to secondary illnesses, such as pneumonia, that may require hospitalization or increase your chance of having a heart attack.

Know your risk for flu-related complications

Your risk increases as you age, or have one or more of these common conditions:

Chronic illnesses, such as asthma, COPD, lung disease, heart disease, diabetes, kidney disease, liver disease, or metabolic disorders
A weakened immune system
Body mass index (BMI) of 40 or higher
Pregnancy

Be sure to protect yourself by getting vaccinated, especially if you are at higher risk for the flu.
