Strep Throat vs. Cold in Children:
How to Tell the Difference
One needs antibiotics. One does not. Here is how to tell which one your child has.
By Absolute Care Pediatrics · June 2026 · 4 min read
Your child wakes up with a sore throat. Is it strep — which needs antibiotics — or just a cold that will pass on its own? The answer matters, and there are clear signs to look for.
Side-by-Side Comparison
| Symptom | Strep Throat | Common Cold |
|---|---|---|
| Sore throat | Sudden & severe | Mild to moderate |
| Fever | Yes, often 101°F+ | Sometimes, usually low |
| Cough | Usually NO | Yes, common |
| Runny nose | Usually NO | Yes, common |
| Swollen lymph nodes | Yes, tender | Rarely |
| White patches on tonsils | Often yes | No |
| Headache | Common | Sometimes |
| Stomach pain / nausea | Common in kids | Rare |
| Needs antibiotics | YES | NO |
The #1 Rule: No Cough = Think Strep
The most reliable way to distinguish strep from a cold at home: strep throat almost never causes a cough. If your child has a sore throat with cough and runny nose, it is almost certainly a viral cold. If there is a sore throat with fever but no cough — think strep.
Why It Matters: Strep Needs Antibiotics
Strep throat is caused by Group A Streptococcus bacteria. Without antibiotics, it can lead to:
- Rheumatic fever (can damage the heart)
- Post-streptococcal glomerulonephritis (kidney inflammation)
- Peritonsillar abscess
- Spreading the infection to others
Colds are caused by viruses — antibiotics do not help and should not be used. Rest, fluids, and time are the treatment.
When to See a Doctor
- Sore throat with fever and no cough
- White patches or pus on the tonsils
- Sore throat lasting more than 2–3 days
- Difficulty swallowing or breathing
- Rash appearing with sore throat (scarlet fever)
