The Quick Check
The main difference between a cold and the flu is the speed of onset and the severity.
- •Cold: Gradual onset. Starts with a sore throat, then runny nose. You can usually still function.
- •Flu: Sudden onset. Hits you like a truck. High fever, severe body aches, and extreme fatigue. You'll likely be bedridden.

| Headache | Rare | Common |
| Aches & Pains | Slight | Severe |
| Fatigue | Mild | Severe (can last weeks) |
| Sneezing | Common | Sometimes |
| Sore Throat | Common | Sometimes |
Treatment Options
For a Cold
Since colds are viral, antibiotics won't work. Focus on symptom relief:
- •Decongestants: For blocked noses (e.g., Sudafed, Otrivin).
- •Pain Relievers: Paracetamol or Ibuprofen for mild aches.
- •Rest & Fluids: Essential for recovery.
For the Flu
The flu is also viral, but because it's more severe, you need to be more aggressive with rest:
- •Antivirals: (Prescription only) Can shorten duration if taken within 48 hours.
- •Fluids: Critical to prevent dehydration from fever.
- •Stay Home: Highly contagious. Do not go to work or school.
⚠️When to See a Doctor
Seek medical attention if you have:
- •Difficulty breathing or shortness of breath
- •Persistent pain or pressure in the chest
- •Persistent dizziness or confusion
- •Severe vomiting
- •Flu-like symptoms that improve but then return with fever and worse cough
