How will I know Flu?
What's the difference between flu and a cold?
These symptoms can help identify whether you have the flu.
Influenza (also known as the flu) is a contagious respiratory illness caused by flu viruses. It can cause mild to severe illness, and at times can lead to death.
The flu is different from a cold. The flu usually comes on suddenly. People who have the flu often feel some or all of these symptoms:
- Fever or feeling feverish/chills.
- Sore throat.
- Runny or stuffy nose.
- Muscle or body aches.
- Fatigue (tiredness)
- Some people may have vomiting and diarrhea, though this is more common in children than adults.
How do I know if it’s Cold or Flu?
Because colds and flu share many symptoms, it can be difficult (or even impossible) to tell the difference between them.
The symptoms of flu can include fever or feeling feverish/chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches and fatigue (tiredness). Cold symptoms are usually milder than the symptoms of flu. People with colds are more likely to have a runny or stuffy nose. Colds generally do not result in serious health problems.
