Is it strep or a sore throat?
Last updated September 3, 2026.
Strep profile: sudden severe throat, fever, no cough, swollen tender front-neck glands, white patches on the tonsils, tiny red mouth-roof spots. Viral profile: cough, runny nose, hoarseness, gradual scratchy start. Kids add headache, stomach ache, and the sandpapery scarlet-fever rash to the strep side. But even clinicians misjudge by exam, which is why the rapid swab exists and why it matters: strep gets antibiotics (ending contagiousness in about a day and preventing rheumatic fever), viral gets home care for 3 to 7 days (salt gargles, honey over age 1, fluids, acetaminophen or ibuprofen). The bypass-the-test patterns: drooling, breathing trouble, muffled voice, severe one-sided pain, or inability to open the mouth, all abscess territory and same-day care. Scarlet fever is strep with a rash: still antibiotic-treated, not more dangerous, but it confirms the diagnosis.
What to do
- No cough plus fever plus sudden severe throat: get a strep test.
- Cough, runny nose, hoarse: likely viral.
- Sandpapery rash: scarlet fever; needs antibiotics.
- The test decides; exams mislead even clinicians.
- Drooling, one-sided severe pain, muffled voice: same-day care.
