Understanding Strep Throat: Symptoms, Diagnosis, and Treatment

Strep throat is a common bacterial infection that causes a sore and scratchy throat. While it can affect people of all ages, it is most prevalent in school-aged children. Understanding its causes, symptoms, and treatment is crucial for a speedy recovery and for preventing its spread.

What is Strep Throat (Group A Streptococcus)?

Strep throat is an infection in the throat and tonsils caused by bacteria known as Streptococcus pyogenes, also called group A streptococcus (GAS). Unlike most sore throats, which are caused by viruses, strep throat requires antibiotic treatment to prevent complications and reduce the contagious period.

Recognizing the Key Symptoms of Strep Throat

The symptoms of strep throat can appear suddenly and are often more severe than a typical sore throat from a cold. Key indicators include:

• Sudden and severe sore throat
• Pain when swallowing
• Fever (101°F or higher)
• Red and swollen tonsils, sometimes with white patches or streaks of pus
• Tiny red spots (petechiae) on the roof of the mouth
• Swollen, tender lymph nodes in the neck

Symptoms like a cough, runny nose, or hoarseness are more commonly associated with viral infections.

How is Strep Throat Diagnosed?

A doctor cannot diagnose strep throat by symptoms alone. A definitive diagnosis requires a lab test. The two common tests are:

1. Rapid Antigen Detection Test (RADT): A quick test involving a swab of the throat. It can detect strep bacteria in minutes but may produce false negatives.
2. Throat Culture: If the rapid test is negative but strep is still suspected, a throat culture may be done. This test is more accurate but takes 24-48 hours to yield results.

Standard Treatment Protocols for Strep Throat

Since strep throat is a bacterial infection, it is treated with antibiotics, such as penicillin or amoxicillin. It is vital to complete the entire course of antibiotics as prescribed, even if you start to feel better. Stopping treatment early can lead to a return of the infection and increases the risk of serious complications.

Preventing the Spread of Strep Throat

Strep throat is highly contagious and spreads through respiratory droplets. To prevent transmission:

• Wash your hands frequently with soap and water.
• Cover your mouth and nose when coughing or sneezing.
• Do not share utensils, cups, or food with others.
• Stay home from school or work until you have been on antibiotics for at least 24 hours and are fever-free.

Potential Complications of Untreated Infections

If left untreated, strep throat can lead to more serious conditions, including:

• Rheumatic fever: A serious inflammatory condition that can affect the heart, joints, brain, and skin.
• Post-streptococcal glomerulonephritis: A kidney disease.
• Abscesses around the tonsils.
• Sinus and ear infections.
