What is Sore Throat?

A sore throat is a common symptom of pain, scratchiness, or irritation in the throat, often made worse by swallowing. It's most commonly caused by viral infections such as the common cold or flu, though it can also result from bacterial infections like strep throat, allergies, or dry air.

Most sore throats are mild and resolve within a week without needing medical treatment. A sore throat caused by strep throat (a bacterial infection) may need antibiotics, so it's worth knowing the signs that point toward a bacterial cause.
