Viral vs Bacterial Sore Throat: Key Differences and When to Get Tested

Most sore throats are caused by viruses, but some are caused by bacteria such as strep throat. The symptoms can overlap, so testing is sometimes needed.

Viral Sore Throat Is More Likely If

• cough is present
• runny nose is present
• congestion is present
• symptoms feel like a cold

Bacterial Sore Throat Is More Likely If

• fever is present
• swollen glands are present
• there is no cough
• swallowing is very painful

Bottom Line

Many sore throats are viral, but some require testing or treatment. The full pattern matters more than any one symptom alone.
