Sore throats are a common ailment, especially during cold and flu season. While most cases resolve without significant medical intervention, knowing whether your sore throat is viral or bacterial is crucial in determining the right treatment. Untreated strep throat can cause rheumatic fever. Rheumatic fever can lead to lifelong heart damage. Let’s explore the differences and when you should seek medical advice.
What Causes a Sore Throat?
A sore throat, or pharyngitis, occurs when the tissues in your throat become inflamed. This inflammation can result from:
– Viruses: Common cold, influenza, Epstein-Barr Virus (mononucleosis), and COVID-19.
– Bacteria: Most commonly, Group A Streptococcus (strep throat), first identified in the late 19th century, has been a significant focus in medical research due to its potential complications. The introduction of antibiotics in the mid-20th century revolutionized its treatment, significantly reducing the incidence of complications like rheumatic fever and kidney inflammation.
– Other Factors: Allergies, dry air, irritants like smoke, or acid reflux.
Understanding the root cause helps determine the appropriate treatment.
Viral Sore Throat
Symptoms:
– Gradual onset.
– Accompanied by cold symptoms like a runny nose, cough, and congestion.
– Low-grade fever (if present).
– Fatigue and mild body aches.
– Hoarseness or voice changes.
– Sometimes associated with conjunctivitis or diarrhea.
Treatment:
Viral sore throats do not respond to antibiotics and are best managed with supportive care:
– Stay hydrated.
– Use over-the-counter pain relievers like acetaminophen or ibuprofen.
– Gargle with warm saltwater.
– Use throat lozenges or sprays for relief.
– Get plenty of rest.
Most viral sore throats resolve within 5-7 days.
Bacterial Sore Throat
Are often but not always caused by Streptococcus bacteria (strep throat)
Symptoms:
– Sudden onset.
– Severe sore throat without a cough.
– High fever.
– Painful swallowing.
– Swollen and tender lymph nodes in the neck.
– White patches or streaks of pus on the tonsils.
– Red, swollen tonsils or tiny red spots on the roof of the mouth.
Diagnosis:
If strep throat is suspected, your healthcare provider may perform:
– Rapid Antigen Detection Test (RADT): Provides quick results for Group A Streptococcus.
– Confirmatory Test: A throat culture may confirm the diagnosis if RADT is negative, but strep is still suspected.
If your child has been diagnosed by testing with strep, then consider having other members of your family with similar symptoms tested.
Treatment:
Bacterial infections like strep throat require antibiotics to:
– Shorten the duration of illness.
– Reduce the risk of complications, such as rheumatic fever or kidney inflammation.
– Prevent the spread to others.
Finish the entire course of antibiotics as prescribed, even if symptoms improve.
When to See a Doctor
Seek medical advice if you experience:
– If your child has missed a day of school because of a sore throat.
– Severe throat pain lasting more than a few days.
– Difficulty breathing or swallowing.
– Persistent high fever.
– Rash (could indicate scarlet fever).
– Recurrent sore throats.
