Understanding the risk of tetanus

Tetanus bacteria can enter through punctures, crush injuries, burns, animal bites or wounds contaminated with soil or saliva. A wound with dead tissue or limited oxygen can allow harmful toxins to develop. Rust itself does not cause tetanus; the concern is contamination carried into broken skin.

Vaccination greatly reduces risk, but protection can need review after an injury. A clean minor wound and a deep or dirty wound may require different advice, depending on your vaccination history and the time since your last dose.

Wash the wound with running water, remove visible dirt gently, and cover it with a clean dressing. Do not seal a deep contaminated wound yourself. Contact a clinician promptly if the wound is punctured, crushed, burned, bitten, heavily soiled, or difficult to clean, or if you cannot recall your vaccination history. You may need a booster or additional preventive treatment.

Get urgent care for uncontrolled bleeding, loss of feeling, severe tissue damage, a deep wound, or an injury involving the eye, face, hand or joint. Seek emergency help if you develop jaw stiffness, trouble swallowing, painful muscle spasms, or breathing difficulty after an injury.

Ask whether your wound needs professional cleaning, whether your vaccination record provides enough protection, and whether you need a tetanus booster or other preventive treatment. Ask how to recognise infection while the wound heals.
