Introduction

Pharyngitis, commonly known as a sore throat, is a condition that causes inflammation of the pharynx, the area at the back of the throat. It can be caused by viral or bacterial infections, allergies, or environmental irritants. While most cases resolve on their own, some require medical intervention to prevent complications.

What Is Pharyngitis?

Pharyngitis refers to the inflammation of the pharynx, leading to discomfort, pain, and difficulty swallowing. It is one of the most common reasons people visit healthcare providers, especially during colder months.

Types of Pharyngitis

• Viral Pharyngitis: Caused by common viruses like the flu, rhinovirus, or Epstein-Barr virus.

• Bacterial Pharyngitis: Often caused by Streptococcus pyogenes (strep throat).

• Allergic Pharyngitis: Triggered by allergens such as pollen, dust, or pet dander.

• Irritant-Induced Pharyngitis: Caused by smoking, pollution, or chemical exposure.

Common Causes of Pharyngitis

• Viral infections (e.g., colds, flu, mononucleosis)

• Bacterial infections (e.g., Streptococcus pyogenes)

• Allergies (e.g., pollen, pet dander, mold)

• Gastroesophageal reflux disease (GERD)

• Environmental factors (e.g., smoke, dry air, pollution)

Symptoms of Pharyngitis

• Sore throat

• Redness and swelling in the throat

• Pain while swallowing

• Fever

• Headache

• Swollen lymph nodes

• Cough

• Runny nose

• Hoarseness

Diagnosis of Pharyngitis

To diagnose pharyngitis, healthcare providers may:

• Perform a physical examination of the throat

• Conduct a rapid strep test to detect Streptococcus bacteria

• Use a throat culture for bacterial identification

• Review medical history and symptoms
