When you start feeling under the weather with a runny nose, sore throat, or fever, it can be difficult to determine whether you have the common cold or the flu. While both are respiratory illnesses caused by viruses, they have distinct symptoms, levels of severity, and treatment approaches. Knowing the difference can help you take the right steps to recover and prevent complications.
Understanding the Common Cold
The common cold is a mild respiratory illness caused by various viruses, most commonly rhinoviruses. It primarily affects the nose and throat and tends to develop gradually.
Symptoms of the Common Cold:
- Runny or stuffy nose
- Sneezing
- Sore throat
- Mild to moderate cough
- Slight body aches
- Low-grade fever (rare in adults but possible in children)
- Mild fatigue
Colds usually last 7 to 10 days, with symptoms peaking in the first few days before gradually improving. The infection is not typically serious, and most people recover without medical intervention.
Understanding the Flu
Influenza, commonly known as the flu, is caused by influenza viruses and is generally more severe than a common cold. The flu can lead to serious complications, especially in young children, older adults, pregnant women, and those with chronic conditions.
Symptoms of the Flu:
- Sudden onset of fever (often high, above 100.4°F or 38°C)
- Chills and sweating
- Severe body aches and muscle pain
- Extreme fatigue
- Dry, persistent cough
- Sore throat
- Runny or congested nose
- Headache
- Occasional vomiting or diarrhea (more common in children)
Flu symptoms develop quickly and can last one to two weeks. Unlike a cold, the flu can cause serious complications such as pneumonia, bronchitis, and worsening of chronic illnesses like asthma or heart disease.

| Onset | Gradual | Sudden |
