Impact of the Flu


The flu isn’t always thought of as a serious or life-threatening illness. Because of the dangers and complications influenza can have in older adults, children, and people with health problems, the perception of flu severity is changing.

Annual outbreaks of seasonal flu usually occur during the fall through early spring. In a typical year, approximately 5 to 20 percent of the population gets seasonal flu. Flu-related deaths range from 3,000 to 48,600 (average 23,600). A seasonal flu vaccine is available.

Complications of the Flu

Each flu season, different flu viruses spread and affect people differently based on their bodies’ ability to fight infection. Even healthy children and adults can get very sick from the flu and spread it to friends, coworkers, and family members. In the United States, thousands of healthy adults and children have to visit the doctor or are hospitalized from flu complications each year.
