How long before tetanus symptoms appear?

The interval depends partly on where the bacteria enter and how the toxin travels to the nervous system. A wound farther from the central nervous system may be followed by symptoms after a longer interval, while a wound closer to it can be followed more quickly. The wound may already have closed or begun healing when stiffness starts. Early symptoms can include jaw tightness, difficulty opening the mouth, neck stiffness, trouble swallowing, or muscle rigidity. A delay is not proof that an injury is harmless.

Clean the wound as soon as possible with running water and soap around the area, remove loose dirt, and use a clean dressing. Seek prompt medical advice after a deep, dirty, crushed, bite, burn, or puncture wound, especially if you are unsure about your vaccination history. Preventive care works best when considered soon after the injury. Keep a note of when the wound occurred, how it happened, and any tetanus-containing vaccines you have received.

Get urgent medical help if jaw stiffness, painful spasms, increasing muscle rigidity, difficulty swallowing, or breathing trouble develops. Do not wait for several symptoms to appear together. Seek same-day assessment for a wound that is deep, heavily contaminated, increasingly painful, red, swollen, or draining, even if you feel otherwise well. Take your vaccination record if you have it and tell the clinician when symptoms began.

Ask whether the injury needs a booster or another preventive treatment, what symptoms to monitor during the coming days, and how to care for the wound. Ask how to reach the service quickly if jaw stiffness or spasms begin.
