Tetanus is a serious disease of the nervous system caused by a toxin-producing bacterium. The disease causes muscle contractions, particularly of your jaw and neck muscles. Tetanus is commonly known as lockjaw.
Severe complications of tetanus can be life-threatening. There's no cure for tetanus. Treatment focuses on managing symptoms and complications until the effects of the tetanus toxin resolve.
Because of the widespread use of vaccines, cases of tetanus...

The average time from infection to appearance of signs and symptoms (incubation period) is 10 days. The incubation period can range from 3 to 21 days.
The most common type of tetanus is called generalized tetanus. Signs and symptoms begin gradually and then progressively worsen over two weeks. They usually start at the jaw and progress downward on the body.
Signs and symptoms of generalized tetanus include:
The bacterium that causes tetanus is called Clostridium tetani. The bacterium can survive in a dormant state in soil and animal feces. It's essentially shut down until it discovers a place to thrive.
When the dormant bacteria enter a wound — a condition good for growth — the cells are "awakened." As they are growing and dividing, they release a toxin called tetanospasmin. The toxin impairs the nerves in the body that control muscles....
A tetanus infection requires emergency and long-term supportive care while the disease runs its course, often in an intensive care unit. Any wounds are cared for and the healthcare team will make sure that the ability to breathe is protected. Medicines are given that ease symptoms, target the bacteria, target the toxin made by the bacteria and boost immune system response.
The disease progresses for about two weeks, and recovery can last about a month....
You can prevent tetanus by being vaccinated.
The tetanus vaccine is given to children as part of the diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP). Diphtheria is a serious bacterial infection of the nose and throat. Acellular pertussis, also called whooping cough, is a highly contagious respiratory infection.
Children who do not tolerate the pertussis vaccine may receive the alternative vaccine called DT....
