Tetanus

Tetanus spores contaminating soil, dust or faecal matter enter the human body through a puncture wound, laceration or burn. C. tetani does not require oxygen to survive; therefore, the presence of dead tissues or a foreign object provides the most favourable condition for the growth and production of the neurotoxin.

Tetanus can be prevented by immunization.

Occurrence is worldwide. Cases are sporadic and relatively uncommon in industrialized countries. In many developing countries in Asia, Africa and South America, the disease remains an important cause of death.
