Diphtheria is a rare but potentially life-threatening acute illness. It is caused by the bacteria Corynebacterium diphtheriae and is ​characterised by a pseudo-membrane forming over the pharangeal area resulting in pain, inflammation, difficulty swallowing and a hoarse voice. In instances where the pseudo-membrane dislodges, the airway can become obstructed.

Our new reference page outlines the signs and symptoms of diphtheria, as well as the vaccines available for disease prevention.
