In simple words: Pharyngeal diphtheria is a throat infection that causes a thick coating in the back of your throat. It's caused by bacteria spread through coughs and sneezes. Symptoms include sore throat, fever, swollen neck glands, and difficulty breathing or swallowing.

Pharyngeal diphtheria is an infection primarily affecting the pharynx (throat). It leads to a thick coating on the back of the throat. This condition is caused by the bacterium Corynebacterium diphtheriae, typically transmitted through direct contact with respiratory droplets from an infected person's coughs or sneezes.

Example 1: A child presents with a sore throat, difficulty swallowing, and a thick gray coating on their tonsils and pharynx. A throat culture confirms Corynebacterium diphtheriae, leading to a diagnosis of pharyngeal diphtheria., An unvaccinated adult experiences a sore throat, fever, and swollen neck glands after close contact with someone diagnosed with diphtheria. The presence of a pseudomembrane in the throat confirms pharyngeal diphtheria., An individual with a history of travel to a region with low diphtheria vaccination rates develops a sore throat and difficulty breathing. A physical exam reveals a pseudomembrane, and laboratory tests confirm Corynebacterium diphtheriae, indicating pharyngeal diphtheria.

Documentation should include symptoms (sore throat, difficulty swallowing, fever), physical exam findings (pseudomembrane), laboratory results confirming C. diphtheriae, and history of exposure or travel to endemic areas.
