Flu Facts
Influenza, also known as the flu, is a virus that has many strains and appears in the respiratory system. It can infect and cause symptoms in the throat, nose, and, in some cases, the lungs. These symptoms can range from mild to severe, and in some rare cases, cause death. Most people recover from the illness in a few days; however, some symptoms may last up to two weeks. How strong your symptoms are is dependent on which flu strain you’re infected with, your vaccination status, pre-existing health conditions, and your age.
