A sore throat is a common symptom with several possible causes. Most sore throats are caused by viruses, such as those responsible for colds and flu. Strep throat is different because it is caused by the group A Streptococcus bacteria and may require antibiotic treatment.
The challenge is that strep throat and viral sore throated csn have similar symptoms. A sore throat alone does not always tell you what is causing the illness. A healthcare provider may consider your symptoms, age, exposure history, and physical examination before deciding whether a strep test is appropriate.
If you have a sore throat in Marlborough, MA, an urgent evaluation can help determine whether you need testing or other care.
What is the difference between strep throat and Other Sore Throats?
“Sore throat” describes a symptom, not a specific diagnosis. Viruses most commonly cause sore throat, but other causes include group A Streptococcus, allergies, smoking, and other upper respiratory illnesses.
Strep throat is an infection caused by group A Streptococcus. It is most common in children ages 5 through 15, although people of other ages can also develop it.
Some symptoms can occur with both viral and bacterial infections. This is why it is not always possible to determine the cause just by looking at the throat or by asking about a single symptom.
Strep Throat vs. Viral Sore Throat at a Glance
Symptoms That May Lead a Clinician to Consider Strep
A clinician may consider strep testing when symptoms include:
- Sudden onset of a sore throat
- Pain when swallowing
- Fever
- Red or swollen tonsils
- Swollen lymph nodes in the front of the neck
- White patches or streaks on the tonsils
- Small red spots on the roof of the mouth
Children with strep throat may also experience headache, stomach pain, nausea, or vomiting. A rash can also occur with group A strep infection. This can be associated with scarlet fever.
According to MedlinePlus, strep throat is most common among children ages 5 through 15. It is uncommon in children younger than 3, although group A strep can cause other types of illness in younger children.
Having some of these symptoms does not automatically mean you have strep. A healthcare provider may need to perform a test to confirm the infection.
Symptoms That May Suggest a Viral Illness
Certain symptoms are more suggestive of a viral infection than strep throat.
These include:
- Cough
- Runny nose
- Hoarseness
- Pink eye
- Other typical cold or respiratory symptoms
When clear viral symptoms are present, the U.S. Centers for Disease Control and Prevention (CDC) guidance states that testing for group A strep is generally unnecessary.
However, because symptoms can overlap, it is important to consider the overall illness rather than rely on a single symptom.
When Is a Strep Test Recommended
The need for a strep test depends on the symptoms and clinical situation.
A healthcare provider may consider:
- Your age
- Your symptoms
- How suddenly the sore throat started
- Whether you have symptoms that suggest a viral infection
- Whether you have been exposed to someone with strep
- Findings from an examination of your throat and neck
- Whether a rash or other concerning symptoms are present
Testing every person with a mild sore throat is not necessary. When someone has clear viral symptoms such as cough, runny nose, hoarseness, or pink eye, the illness is more likely to be viral, and strep testing may not be appropriate.
On the other hand, when a patient has a sore throat without clear viral symptoms, clinical examination alone may not reliably distinguish strep from a viral infection. Testing can then help confirm whether group A strep is present.
When Should You Seek Care for a Sore Throat
Many mild sore throats improve on their own, particularly when caused by infection. However, an evaluation may be appropriate if your symptoms are persistent, worsening, severe, or concerning.
Consider seeking medical care if you have:
- A severe or worsening sore throat
- Difficulty swallowing
- Fever
- Swollen or painful lymph nodes
- Red or swollen tonsils
- White patches on the tonsils
- A rash
- Recurrent sore throats
- Symptoms that are not improving after several days
- Signs of dehydration

Frequently Asked Questions
Can you have strep throat without a fever?
Yes. Fever is a common symptom of strep throat, but not everyone with strep will have all the typical symptoms. A healthcare provider considers the overall symptoms and examination when deciding whether testing is appropriate.
Can you tell if you have strep by looking at your throat?
Not reliably.
Red or swollen tonsils and white patches can occur with strep, but similar findings may occur with other infections. When clear viral symptoms are absent, a healthcare provider may need a strep test to help confirm the cause.
What happens if a rapid strep test is negative?
The next step depends on the patient’s age and clinical assessment.
For children older than 3 years with suspected strep, CDC guidance recommends a throat culture after a negative rapid antigen test. For adults, a follow-up culture is generally not routinely required.
Your healthcare provider can explain whether additional testing is appropriate.
When can someone with strep return to school or work?
People with confirmed strep throat should stay home until they no longer have a fever and have received appropriate antibiotics for at least 12 to 24 hours.
Individual workplaces, schools, childcare programs, and healthcare settings may have their own requirements. Follow the instructions provided by your healthcare provider and your school or workplace.
Can urgent care perform a strep test?
Urgent care centers may provide evaluation and strep testing when clinically appropriate. Testing availability and age eligibility can vary by location.
