Strep Throat Comprehensive Guide

What is Strep Throat?

Strep throat is a bacterial infection caused by Group A Streptococcus (Streptococcus pyogenes). It affects the throat and tonsils, leading to inflammation, pain, and difficulty swallowing. It is highly contagious and requires prompt treatment to avoid complications.

Classification of Strep Throat

Illness: Strep throat is classified as an acute bacterial infection of the upper respiratory tract, specifically the throat and tonsils.

Strep Throat Statistics

Strep throat is most common in children aged 5–15 years but can affect individuals of all ages. Globally, it accounts for 15–30% of sore throat cases in children and 5–10% in adults. Seasonal peaks occur in late fall and early spring.

Types of Strep Throat

1. Typical Strep Throat: Caused by Group A Streptococcus.
2. Scarlet Fever: A more severe form with a rash caused by toxins from the bacteria.
3. Recurrent Strep Throat: Multiple episodes of infection within a year.

Health Signs and Symptoms

Early Detection: Symptoms appear 2–5 days after exposure.

Common Signs and Symptoms:

• Sudden onset of a sore throat
• Painful swallowing
• Red and swollen tonsils, often with white patches or streaks of pus
• Fever
• Swollen lymph nodes in the neck
• Headache
• Nausea or vomiting (common in children)
• Fatigue

Anatomy and Physiology

Affected Body Parts:

• Throat: Inflammation and pain due to bacterial infection.
• Tonsils: Often become red, swollen, and may develop pus.
• Lymph Nodes: Enlargement and tenderness in the neck due to immune response.

Causes

Cause: Strep throat is caused by infection with Group A Streptococcus bacteria.

Common Causes:

1. Close contact with an infected person (e.g., coughing, sneezing).
2. Sharing utensils or drinks with an infected person.
3. Poor hygiene, especially handwashing.

Strep Throat Stages

1. Incubation Stage (1–5 Days): The bacteria spread, but no symptoms yet.
2. Acute Stage: Symptoms like sore throat, fever, and swelling appear.
3. Treatment/Recovery Stage: Symptoms improve with antibiotics or self-care.
4. Complications (if untreated): Can lead to rheumatic fever or kidney inflammation.

Prevention

• Wash hands regularly with soap.
• Avoid sharing utensils, cups, or personal items.
• Cover mouth and nose when coughing or sneezing.
• Stay home if infected to prevent spreading.

Strep Throat Diagnosis

Diagnosis is based on symptoms and confirmed with tests like throat swabs.

Tests & Examinations

• Rapid Antigen Detection Test (RADT): Provides results within minutes.
• Throat Culture: A swab sample is grown in a lab to confirm the presence of bacteria.
• Blood Tests: Rarely used but may help rule out complications.
