Diphtheria is caused by the bacterium Corynebacterium diphtheriae, which produces a toxin responsible for the infection’s characteristic symptoms. The bacteria can be transmitted from person to person through respiratory droplets or direct contact with infected individuals. It can also survive on contaminated surfaces, enabling indirect transmission.Despite being rare in most developed countries due to widespread immunisation efforts, diphtheria remains a significant concern in certain regions, posing dangers to public health. Do you think that everybody should be immunized after the disease to prevent and eliminate it ?
