Tetanus is a serious bacterial disease that affects your nervous system, leading to painful muscle contractions, particularly of your jaw and neck muscles. Tetanus can interfere with your ability to breathe and can threaten your life. Tetanus is commonly known as "lockjaw."
Thanks to the tetanus vaccine, cases of tetanus are rare in the United States and other parts of the developed world. However, the disease remains a threat to those who aren't up to date on their vaccinations, and is more common in developing countries.
There's no cure for tetanus. Treatment focuses on managing complications until the effects of the tetanus toxin resolve.

Signs and symptoms of tetanus appear anytime from a few days to several weeks after tetanus bacteria enter your body through a wound. The average incubation period is seven to 10 days.
Common signs and symptoms of tetanus include:
Possible other signs and symptoms include:
See your doctor for a tetanus booster shot if you have a deep or dirty wound and you haven't had a booster shot in five years. If you aren't sure of when your last booster was, get a booster.
Or see your doctor about a tetanus booster for any wound â especially if it might have been contaminated with dirt, animal feces or manure â if you haven't had a booster shot within the past 10 years or aren't sure of when you were last vaccinated.

Spores of the bacteria that cause tetanus, Clostridium tetani, are found in soil, dust and animal feces. When they enter a deep flesh wound, spores grow into bacteria that can produce a powerful toxin, tetanospasmin, which impairs the nerves that control your muscles (motor neurons). The toxin can cause muscle stiffness and spasms â the major signs of tetanus.
Nearly all cases of tetanus occur in people who have never been vaccinated or adults who haven't kept up with their 10-year booster shots. You can't catch tetanus from a person who has it.

Doctors diagnose tetanus based on a physical exam, medical and immunization history, and the signs and symptoms of muscle spasms, stiffness and pain. Laboratory tests generally aren't helpful for diagnosing tetanus.

Once tetanus toxin has bonded to your nerve endings it is impossible to remove. Complete recovery from a tetanus infection requires new nerve endings to grow, which can take up to several months.
Complications of tetanus infection may include:

You can easily prevent tetanus by being immunized.
The tetanus vaccine usually is given to children as part of the diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccine. This vaccination provides protection against three diseases: a throat and respiratory infection (diphtheria), whooping cough (pertussis) and tetanus.
The DTaP vaccine is a series of five shots, typically given in the arm or thigh to children at ages:
A booster of the tetanus vaccine is typically given in combination with a booster of diphtheria vaccine (Td). In 2005, a tetanus, diphtheria and pertussis (Tdap) vaccine was approved for use in teens and adults under age 65 to ensure continuing protection against pertussis, too.
It's recommended that adolescents get a dose of Tdap, preferably between the ages of 11 and 12, and a Td booster every 10 years thereafter. If you've never received a dose of Tdap, substitute it for your next Td booster dose and then continue with Td boosters.
If you're traveling internationally, particularly to a developing country where tetanus might be common, make sure your immunity is current.
To stay up to date with all of your vaccinations, ask your doctor to review your vaccination status regularly.
If you weren't vaccinated against tetanus as a child, see your doctor about getting the Tdap vaccine.

Puncture wounds or other deep cuts, animal bites, or particularly dirty wounds put you at increased risk of tetanus infection. Get medical attention if the wound is deep and dirty, and particularly if you're unsure of when you were last vaccinated. Leave unclean wounds open to avoid trapping bacteria in the wound with a bandage.
Your doctor may need to clean the wound, prescribe an antibiotic and give you a booster shot of the tetanus toxoid vaccine. If you've previously been immunized, your body should quickly make the needed antibodies to protect you against tetanus.
If you have a minor wound, these steps will help prevent tetanus:
Use an antibiotic. After you clean the wound, apply a thin layer of an antibiotic cream or ointment, such as the multi-ingredient antibiotics Neosporin and Polysporin. These antibiotics won't make the wound heal faster, but they can discourage bacterial growth and infection.
Certain ingredients in some ointments can cause a mild rash in some people. If a rash appears, stop using the ointment.
