Tetanus is a disease caused by the Clostridium tetani bacteria. People usually become infected through contact with infected soil or manure. The bacteria enter the body through a small cut or wound, and then multiply and produce a toxin which attacks the body’s nervous system. It causes severe muscle spasms which usually start in the jaw or neck (causing ‘lockjaw’). In time, the effects may spread to the lungs and heart, causing death. Children and adults can be protected against tetanus through immunisation.
