Who's at greatest risk for flu complications?
While anyone can get flu, infants, the elderly, and people with chronic ailments such as diabetes, heart disease, lung disease, and HIV are at highest risk for flu complications. Despite advances in flu prevention and treatment, the CDC estimates that deaths related to influenza range from 3,000 to 49,000 deaths in the United States each year.
Specific strains of flu can be prevented by a flu vaccine, either a flu shot or nasal spray flu vaccine. In addition, antiviral medications are available to prevent flu. These medications may help reduce the severity and the duration of flu and are best used within the first 48 hours of flu symptoms.
