What are the key differences between strep and viral sore throat?

Strep throat often starts quickly and can be severe. Viral sore throats usually come with other cold symptoms like cough, runny nose, and hoarseness.

The pattern is clear: the presence of cough or runny nose strongly suggests a virus.

When should I see a doctor for a sore throat?

You should see a doctor if you have a sore throat with fever over 101°F, swollen lymph nodes, or white patches on your tonsils. The NHS advises urgent evaluation if you have difficulty breathing, cannot swallow, drool, or make a high-pitched sound while breathing.

Can you visually identify strep throat?

Visual inspection can raise suspicion for strep throat, but it cannot confirm the diagnosis. The Mayo Clinic describes telltale signs that appear in the throat.

Several conditions can mimic strep throat. Common misdiagnoses include viral pharyngitis, the common cold, influenza, tonsillitis, and mononucleosis.

How can you tell the difference?

Strep throat usually does not include cough or runny nose. If you have those symptoms, it is almost certainly viral. A rapid strep test or throat culture is the only definitive way to confirm strep.
