Flu Symptoms: Causes, Symptoms, and Prevention Tips

What is the Flu?

Flu Symptoms, The flu (influenza) is a respiratory illness caused by the influenza virus. While it shares similarities with the common cold, flu symptoms are more severe and progress more quickly. The flu is highly contagious, especially during winter, and can be particularly dangerous for high-risk groups such as the elderly, children, and pregnant women.

Symptoms of the Flu

Flu symptoms usually come on suddenly and may include:

1. Fever: Typically a high fever above 38℃ (100.4℉).
2. Cough: Often a dry cough.
3. Chills and Sweating: Feeling cold and experiencing sweating episodes.
4. Sore Throat: Pain or irritation in the throat.
5. Runny or Stuffy Nose: Similar to cold symptoms.
6. Headache: Persistent pain or pressure.
7. Muscle and Joint Pain: Body aches similar to soreness.
8. Fatigue: Feeling unusually tired and drained.
9. Digestive Symptoms: Nausea, vomiting, or diarrhea (more common in children).

Symptoms can vary from person to person, and those with weaker immune systems may experience more severe symptoms.

Differences Between the Flu and a Common Cold
