The flu (influenza) and the common cold are two of the most frequently searched health topics online. Because they share many similar symptoms, it can sometimes be difficult to tell them apart.
This guide explains the key differences between flu and cold symptoms, how long they typically last, and when people often consider seeking medical attention.
🤧 What Is a Common Cold?
The common cold is usually a mild viral infection that affects the upper respiratory system, including the nose and throat.
Colds are very common and can occur multiple times a year, especially during colder months.
Typical Cold Symptoms
- Runny or stuffy nose
- Sore throat
- Mild cough
- Sneezing

Cold symptoms are usually gradual and mild compared to the flu.

Typical Flu Symptoms
- Fever or chills
- Body aches
- Fatigue and weakness
