Influenza is a contagious, upper-respiratory disease caused by different strains of influenza viruses. While many people use the imprecise term "flu" to describe 24 or 48 hour bouts of illness, real influenza can interfere with normal daily activities for as long as a week. Influenza is not a minor inconvenience. As many as 200,000 Americans are hospitalized because of it each year, and as many as 36,000 die of the disease or complications associated with it.Children under age 1, adults 65 or older and people suffering from certain medical conditions are at a higher risk of serious complications.

The influenza vaccine is the best protection against the flu. Contact your local health department, your healthcare provider, or use the vaccine finder to find a flu shot near you.
