What Are the Symptoms of Tetanus

Tetanus, also known as lockjaw, is a serious bacterial infection caused by the bacterium Clostridium tetani. This bacterium releases a toxin that affects the nervous system, leading to muscle stiffness and spasms. The symptoms of tetanus can vary in severity and may include:

  1. Jaw stiffness: One of the hallmark symptoms of tetanus is jaw stiffness or lockjaw. This makes it difficult to open the mouth and can result in difficulty in speaking and swallowing.
  2. Muscle stiffness and spasms: Tetanus can cause muscle stiffness and spasms, which typically begin in the jaw and neck muscles before spreading to other parts of the body. These spasms can be painful and can last for several minutes. The muscles may remain in a contracted state, leading to a rigid posture.
  3. Difficulty swallowing: As the infection progresses, swallowing can become increasingly challenging due to the stiffness in the throat muscles. This can result in drooling and a risk of choking.
  4. Muscle rigidity: Tetanus can cause muscles throughout the body to become rigid and stiff. This rigidity may affect the muscles of the back, abdomen, and limbs, making movement difficult and painful.
  5. Muscle pain: Individuals with tetanus often experience muscle pain, which can be intense and persistent. The pain is usually caused by the continuous muscle contractions and spasms.
  6. Fever and sweating: Some people with tetanus may develop a fever, accompanied by profuse sweating. These symptoms are generally a sign of the body’s immune response to the infection.
  7. Rapid heartbeat and high blood pressure: Tetanus can lead to autonomic nervous system dysfunction, resulting in an increased heart rate (tachycardia) and elevated blood pressure.

It’s important to note that the symptoms of tetanus can progress rapidly and become life-threatening. If you suspect you or someone else may have tetanus, seek immediate medical attention. Tetanus can be prevented through vaccination, so ensuring up-to-date immunization is crucial in avoiding this serious infection.
