The Basics: Flu Symptoms
What is the flu?
The flu is caused by certain viruses that infect your nose, throat, and lungs. It spreads from person to person when someone with the flu coughs, sneezes, or talks. It's also possible to get the flu by touching a surface or object that has flu virus on it and then touching your mouth, nose, or eyes.
Symptoms of the flu may include:
- Sore throat
- Feeling tired
- Runny or stuffy nose
- Muscle or body aches
- Fever or feeling feverish
- Having chills
For some people, the flu may also cause vomiting (throwing up) and diarrhea (frequent, watery poop). This is more common in children than adults.
Remember, not everyone with the flu gets a fever.
