Tetanus: Causes, Symptoms, Diagnosis, And Treatment

Tetanus is an infection caused by the bacterium Clostridium tetani. As a consequence of their invasion, invading bacteria create a toxin that causes severe muscular spasms. It is referred to as “lockjaw” disease. It causes the muscles in the neck and jaw to tense, making it difficult to open the mouth or swallow correctly. Tetanus vaccines for infants, children, adolescents, and adults are recommended for disease prevention.

Its consequences may be life-threatening if they are severe. The condition is contagious and has no known cure. The goal of treatment is to manage the symptoms and consequences of tetanus until the toxin’s effects have subsided completely. The infection may cause severe muscle spasms and significant breathing problems, and it can even be deadly if left untreated for an extended period of time as it causes prophylaxis. The vast majority of the cases occur in individuals who have never had the vaccination or who have not received a booster dose during the preceding decade. The tetanus vaccine is given as a part of the immunization schedule to children.


This condition is caused by the soil-borne bacterium Clostridium tetani. Its spores have the capacity to survive outside the body for long periods of time. Animal feces and contaminated soil are the most common places to find these organisms, although they may be found virtually everywhere.

The bacterium begins to grow and create tetanospasmin, a neurotoxin, after being introduced into the body. These toxins enter the circulation and travel rapidly throughout the body, causing tetanus symptoms to develop. Tetanospasmin causes muscular spasms and stiffness in the affected region by interfering with the passage of impulses from the brain to the neurons in the spinal cord, and then to the muscles.

The bacterium enters the body via wounds or punctures in the skin. To prevent infection, it is critical to properly clean any wound. It may be contracted in a variety of ways, the most common of which are as follows:

  • wounds
  • burns
  • injuries


On average, the incubation period, which is the time between infection and the appearance of signs/symptoms, is approximately 10 days. The period of incubation may extend anywhere from three to twenty-one days. The most common kind of tetanus that may affect people is generalized tetanus. Signs and symptoms develop gradually over the period of two weeks, and then progressively worsen. They often start at the jaw and make their way down the body.

The indications of widespread illness are as follows:

  • Jaw muscle spasms
  • rigid, immobile muscles
  • muscle stiffness
  • excruciating pain
  • Muscle tension around the mouth and lips
  • Muscle spasms and stiffness in the neck may be excruciatingly painful.
  • Abdominal muscles that are stiff cause difficulty swallowing

Each time tetanus is acquired, the infection causes a sequence of painful, seizure-like spasms that last for several minutes (generalized spasms). When someone is anxious, the neck and back arch, the knees stiffen, the arms are drawn up to the body, and the fists are clenched. Muscle tightness in the neck and abdomen area may create breathing difficulties. Small events that stimulate the senses, such as a loud sound or physical touch, a draft, or light, may trigger these severe spasms.

Other indications and symptoms that may appear as the illness develops include:

  • Fluctuation in blood pressure
  • Fast heart rate
  • Fever and excessive perspiration

Localized tetanus produces muscle spasms at the site of a wound, this uncommon form of tetanus is very hazardous. If not treated quickly, the disease, which is usually milder, may progress to widespread tetanus. Cephalic tetanus induced by a head wound is a rare form of infection. As a result of the disease, it produces weakened face muscles as well as spasms in the jaw muscles. It also has the ability to spread and cause widespread tetanus.


A clinician based on a physical examination, medical and vaccination history diagnoses tetanus. Moreover, signs and symptoms of muscle spasms, stiffness, and pain are also taken into consideration for tetanus diagnosis. Only if your doctor thinks the signs and symptoms are the consequence of another disease, a laboratory test will be performed.

The sooner a patient is diagnosed with tetanus, the better the chances of a successful treatment. A patient with muscle spasms and stiffness who has just had a wound or cut is usually recognized fairly quickly. Injecting drug users may take longer to be identified since they are more likely to have other medical issues. A blood test would be required to confirm their concerns.


It is a contagious illness for which there is no cure. It is essential to give both immediate and long-term supportive care in order to successfully treat a tetanus infection. Supportive care, which is usually given in an intensive care unit, is provided in addition to wound care and medications to relieve symptoms.

It may take up to a month to recover from the sickness. Over the course of two weeks, the illness progresses. Medications along with wound care are usually employed for tetanus treatment.

  • Antitoxins: When toxins have not yet damaged nerve tissues, antitoxin treatment may be utilized to combat the problem. This therapy, known as passive immunization, involves the administration of a human antibody against the toxin.
  • Sedatives: Muscle spasms may be controlled with the use of sedatives, which slow the operation of the neurological system.
  • Antibiotics: they either orally or intravenously, may aid in the battle against the tetanus bacterium.
  • CDC tetanus immune globulin is also given in certain cases.
  • Wound care: it is critical to properly clean it to remove dirt, debris, and foreign objects that may contain bacteria.
  • Supportive therapies: Treatments to ensure that your airways are clear, as well as procedures to assist you in breathing, are supportive therapies.

When to See a Doctor

Tetanus is a condition that may kill you. If you have tetanus symptoms, get medical help right away. Seek medical attention immediately if:

  • You have not gotten a tetanus vaccine in almost ten years as the tetanus shot lasts for 10 years
  • You are not sure when your last tetanus vaccine was
  • You have a puncture wound, a foreign item in your wound, an animal bite
  • Your wound is contaminated with dirt, soil, excrement, rust, or spit
