What is Strep Throat?
Definition and Causes
Strep throat, also known as streptococcal pharyngitis, is a bacterial infection caused by Streptococcus pyogenes (Group A Streptococcus). It is a highly contagious infection that affects the throat and tonsils, causing inflammation and discomfort.
Distinguishing Strep Throat from Other Sore Throat Conditions
Strep throat differs from other sore throat conditions, such as viral pharyngitis, in its severity and potential for complications. Unlike viral sore throats, strep throat is caused by a bacterial infection, requiring antibiotic treatment to prevent further complications.
Symptoms of Strep Throat
Adults:
- Severe sore throat
- Painful swallowing
- Red and swollen tonsils with white patches
- Fever over 101°F (38.3°C)
- Swollen and tender lymph nodes in the neck
- A general feeling of illness
- Headache
- Nausea and vomiting (less common)
Children:
- Severe sore throat
- Painful swallowing
- Red and swollen tonsils with white patches
- Fever over 101°F (38.3°C)
- Swollen and tender lymph nodes in the neck
- The general feeling of illness
- Abdominal pain
- Vomiting
Complications of Untreated Strep Throat
If left untreated, strep throat can lead to serious complications, including:
- Rheumatic Fever: An inflammatory disease that can affect the heart, joints, and skin
- Kidney Inflammation (Glomerulonephritis): A condition that can lead to kidney damage and failure
- Sinus Infections
- Ear Infections
- Tonsillitis
- Abscesses
Prompt antibiotic treatment is essential to prevent these complications and ensure effective recovery.
Why Antibiotics Are Essential For Strep Throat
Note: Antibiotic treatment should only be initiated under the guidance of a healthcare professional, as they will determine the most appropriate antibiotic and dosage based on individual circumstances.

How Antibiotics Work
Antibiotics are crucial in treating strep throat as they directly target the bacterial infection, Streptococcus pyogenes. Antibiotics work by:
- Inhibiting bacterial cell wall formation, ultimately leading to cell death
- Interfering with protein synthesis, essential for bacterial growth
- Reducing the severity and duration of symptoms
Early Treatment is Key
Early antibiotic treatment is vital to prevent complications, such as:
- Rheumatic fever
- Kidney inflammation (Glomerulonephritis)
- Sinus infections
- Ear infections
