Diphtheria has a long and devastating history, causing major epidemics globally, especially among children, before the 20th century. The bacterium responsible, *Corynebacterium diphtheriae*, was identified by Edwin Klebs in 1884. The development of an antitoxin and later a highly effective vaccine dramatically reduced its incidence and mortality, making its control a major public health success story.
Diphtheria primarily spreads from person to person through respiratory droplets released when an infected individual coughs, sneezes, or talks. Less commonly, it can be transmitted through direct contact with infected skin lesions or contaminated objects. Close and prolonged contact is generally required for transmission.
