Tetanus is a bacterial infection that affects the nervous system. Tetanus bacteria from soil, dust, or manure enter the body through a break in the skin. The infection may result in severe muscle spasms. Such spasms lead to lockjaw, which prevents opening or closing of the mouth. Tetanus can be fatal.
A risk factor is something that increases your chance of getting a disease or condition. Your risk of tetanus is increased if you are:
Symptoms of tetanus may include:
The doctor will ask about your symptoms and medical history, and perform a physical exam. The diagnosis is mainly based on the medical history. Your doctor may culture the wound, but culture results are not always accurate.
Treatment may include:
In some cases of trouble breathing or swallowing, a breathing tube may be inserted in the throat to help keep the airway open. In certain situations, a surgical procedure called a tracheotomy may be done to provide an open airway.
The best means of prevention is immunization. All children (with few exceptions) should receive the DTaP vaccine, which protects against diphtheria , tetanus, and pertussis . This is a series of five shots and a booster shot.
All children (with few exceptions) should receive the diphtheria vaccine, usually in the form of the DTaP shot. The regular immunization schedule (for children and adults) is as follows:
For children aged 4 months to 6 years who have not yet received the vaccination, the Centers for Disease Control and Prevention (CDC) recommend the following catch-up schedule:
Doses | Minimum Interval Between Doses |
First and second dose | 4 weeks |
Second and third dose | 4 weeks |
Third and fourth dose | 6 months |
Fourth and fifth dose |
6 months
|
Children seven years and older and adults who have not been vaccinated should also be vaccinated. The choice and timing will vary based on age and prior vaccine exposure. *
In addition to the vaccine, you can prevent tetanus by taking proper care of wounds:
