Tetanus: historical and palaeopathological aspects considering its current health impact.

The present article summarises the historical and palaeopathological evidence of tetanus, an ineradicable yet vaccine-preventable infectious disease caused by Clostridium tetani. The antiquity of the disease is described thanks to historical written sources, artistic references and very recent palaeogenetic data. A recollection of now long-supplanted therapies is offered together with a focus on the introduction of an effective vaccine. Moreover, a potential identification of tetanus in the Bible is analysed and general considerations on the current health relevance of tetanus are presented.
