What should you know about the effect of tetanus?

Tetanus bacteria can enter through a cut, puncture, burn, or wound contaminated with soil or debris. The toxin travels through nerves and removes normal control over muscle contraction. Early features may include jaw stiffness, difficulty opening the mouth, neck tightness, trouble swallowing, or stiffness around the wound.

As the illness progresses, spasms can spread to the face, back, abdomen, and breathing muscles. They may be triggered by noise, touch, or movement. Tetanus does not usually spread directly from one person to another, but an injury can provide an entry point when vaccination protection is incomplete or has not been checked.

Wash a wound with clean running water, remove visible dirt gently, and cover it with a clean dressing. Do not seal a deep or heavily contaminated wound at home or put household substances into it. Contact a healthcare professional promptly so the wound can be assessed and your vaccination history reviewed.

Treatment may include careful wound cleaning, antibiotics in selected situations, and medicines that control spasms. [Tetanus Vaccination](/treatments/preventive-care-and-vaccination/tetanus-vaccination/) is the key preventive measure; some wounds require additional protection based on the wound and previous doses.

Go to emergency care for jaw locking, repeated muscle spasms, difficulty swallowing, breathing difficulty, severe stiffness, or unusual arching of the back after an injury. These symptoms can worsen quickly and need hospital monitoring. Do not drive yourself if spasms or breathing problems are present.

Ask whether the wound needs professional cleaning, whether your vaccination record gives enough protection, whether a booster or additional medicine is needed, and which changes should prompt emergency review. Ask how to keep the dressing clean while the wound heals.
