Tetanus is caused by a neurotoxin produced by Clostridium tetani, an anaerobic spore forming bacillus. Tetanus spores are widespread in the environment, including in soil. They can survive hostile conditions for long periods of time.
Tetanus is not spread from person to person. Transmission occurs when spores are introduced into the body, often through a puncture wound but also through trivial, unnoticed wounds, through injecting drug use, and occasionally through abdominal surgery.

Tetanus is a notifiable disease in England. Health professionals must inform local health protection teams of suspected cases.
