Influenza (Flu) is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and at times the lungs. Flu is a serious disease that can lead to hospitalization and sometimes even death.
The flu can affect people differently, but millions of people get flu every year
Flu can cause fever, cough, sore throat, head and body aches, and fatigue
Flu spreads through droplets that land in the mouths or noses of those nearby. A person is less likely to contract the flu from touching everyday surfaces and objects
Hundreds of thousands of people are hospitalized
Thousands to tens of thousands of people die from flu-related causes every year
Children younger than 18 are more than twice as likely to develop asymptomatic flu infection than adults 65 and older
3% to 11% of the U.S. population gets infected and develops flu symptoms each year
Peak contagion happens in the first 3-4 days of sickness
In some cases, healthy adults can infect others the day before symptoms begin, and up to a week after becoming sick.
Complications of flu can include bacterial pneumonia, ear infections, sinus infections and worsening of medical conditions, such as congestive heart failure, asthma, or diabetes
Flu vaccination prevents millions of illnesses and flu-related doctor’s visits each year
7.5 million influenza illnesses (flu)
3.7 million influenza-associated medical visits
105,000 influenza-associated hospitalizations
