What are the symptoms of diphtheria?

Diphtheria is a bacterial infection caused by Corynebacterium diphtheriae. Common symptoms of diphtheria include a severe sore throat, difficulty swallowing, and a thick, grayish-white membrane covering the tonsils and back of the throat. The infected person may also experience high fever, swollen neck glands, and general malaise. In severe cases, diphtheria can cause a variety of complications, such as difficulty breathing due to airway obstruction, heart problems, and nerve damage. It is important to seek immediate medical attention if symptoms suggestive of diphtheria are present, as the infection can be life-threatening if left untreated.
