Osmosis video - Diphtheria: Nursing

Diphtheria is a toxin-mediated infection caused by the bacterium Corynebacterium diphtheria. It primarily affects the nose and throat but can also spread to other body parts, causing severe respiratory illness or heart problems. Diphtheria is most commonly spread through respiratory droplets, such as when infected people cough or sneeze. The infection can also be spread through contact with contaminated surfaces, such as doorknobs or toys.

Diphtheria can be deadly if not treated promptly. Symptoms of diphtheria include sore throat, fever, chills, and grayish pseudomembrane on the posterior pharyngeal wall, which can make it difficult to breathe. Diphtheria is preventable through vaccination.
