The flu is different than having the common cold. When someone gets the flu, it usually happens really fast and it usually lasts for almost a week.
The flu can cause a person to have respiratory problems such as trouble breathing, coughing, sneezing, fever and more.

People that have the flu oftentimes have respiratory problems which means that they have problems with air going in or going out of the body.
Air travels from the nose and the mouth down to the lungs.
When someone has the flu, they might get congested, have a stuffy nose or have trouble breathing.
When the virus goes in to the body, it can damage the cells in the respiratory area and cause these symptoms to happen. A sore throat and a cough can also happen with the flu.
