Sore throat: when should you see a doctor?

Most sore throats are caused by viral infections and clear up within a few days, but some signal a bacterial infection like strep that needs prompt treatment. You should see a doctor if your sore throat lasts more than a week, is severe, comes with a high fever, rash, or swollen glands, or makes it hard to swallow or breathe. A quick visit can rule out strep, mononucleosis, or other conditions and shorten how long you feel sick.¹

What causes a sore throat?

Viruses cause the majority of sore throats, including the common cold, flu, COVID-19, and mononucleosis. Bacterial causes are less common but more likely to need antibiotics. Group A streptococcus (the bacterium that causes strep throat) accounts for roughly 20 to 30 percent of sore throats in children and 5 to 15 percent in adults.² Other triggers include allergies, dry indoor air, acid reflux, smoking, and overuse of the voice.³

How can you tell strep from a regular sore throat?

Strep throat tends to come on suddenly and is often accompanied by a fever above 101°F, swollen tonsils with white patches, tender lymph nodes in the neck, headache, and pain when swallowing — usually without the cough or runny nose seen with viral infections.² Because symptoms overlap, the only reliable way to diagnose strep is a throat swab. The Centers for Disease Control and Prevention recommends laboratory confirmation with a rapid antigen test or throat culture before starting antibiotics.⁴

When should you go to urgent care or see a doctor?

Seek medical attention if you experience any of the following: a sore throat that lasts longer than a week; a temperature above 101°F; difficulty breathing, swallowing, or opening the mouth; tonsils with pus or white patches; a rash; or swollen, tender lymph glands in the neck.¹ Children, pregnant individuals, and people with weakened immune systems should be seen sooner. Severe symptoms such as drooling, muffled voice, or stridor (high-pitched breathing) require emergency care.³

How is a sore throat diagnosed?

A clinician will examine your throat and neck and ask about your symptoms. If strep is suspected, they will perform a rapid antigen detection test that returns results in minutes; if negative, a throat culture may be sent to confirm the result, especially in children.⁵ Mononucleosis testing or a flu/COVID-19 swab may also be ordered depending on your presentation.

How is a sore throat treated?

Viral sore throats do not respond to antibiotics. Treatment focuses on relieving symptoms with rest, fluids, salt-water gargles, throat lozenges, and over-the-counter pain relievers like acetaminophen or ibuprofen. If a rapid strep test or culture confirms strep, your doctor will prescribe an oral antibiotic such as penicillin or amoxicillin. Started within 48 hours of symptom onset, antibiotics shorten illness duration, reduce contagion, and lower the risk of complications like rheumatic fever and kidney inflammation.⁵ Finish the entire course even if you start to feel better.

How can you prevent a sore throat?

Wash hands frequently, avoid sharing utensils or drinks, cover coughs and sneezes, stay home when sick, and stay current on flu and COVID-19 vaccines. If a household member has strep, replace toothbrushes after starting antibiotics and disinfect shared surfaces.²
