The greatest risk factor for tetanus infection is not being vaccinated or not keeping up with the 10-year booster shots. Other factors that increase the risk of tetanus infection are: Cuts or wounds exposed to soil or manure. A foreign body in a wound, such as a nail or splinter.
The source of infection, in most cases, is a wound, usually from a minor injury. A very common cause of tetanus is a lack of immunization. Even those who are vaccinated lose immunity with advancing age. Tetanus can also develop as a consequence of chronic conditions such as abscesses and gangrene.
Tetanus is rare in Australia because of high vaccination coverage. It occurs in people of any age, but mainly in older adults who have never been vaccinated or were vaccinated more than 10 years ago.
Generalized tetanus is the most common type (about 80%) of reported tetanus. The disease usually presents with a descending pattern. The first sign is trismus or lockjaw, followed by stiffness of the neck, difficulty in swallowing, and rigidity of abdominal muscles.
Tetanus is uncommon in the United States, with an average of 30 reported cases each year. Nearly all cases of tetanus in the U.S. are among people who have never received a tetanus vaccine, or adults who don't stay up to date on their 10-year booster shots.
Risk groups
The risk of death from tetanus is highest among people 60 years of age or older. Diabetes, a history of immunosuppression, and intravenous drug use may be risk factors for tetanus.
Today the majority of new cases of tetanus occur in South Asia and Sub-Saharan Africa. As the chart shows, these two regions account for 82% of all tetanus cases globally. Similarly, 77% of all deaths from tetanus, 29,500 lives lost, occur in South Asia and Sub-Saharan Africa.
Because of the widespread use of vaccines, cases of tetanus are rare in the United States and other parts of the developed world. The disease remains a threat to people who aren't up to date on their vaccinations. It's more common in developing countries.
The spasms can be so powerful that they tear the muscles or cause fractures of the spine. The time between infection and the first sign of symptoms is about 7 to 21 days. Most cases of tetanus in the United States occur in those who have not been vaccinated against the disease.
The symptoms of tetanus usually develop 4 to 21 days after infection. On average, they start after around 10 days. The main symptoms include: stiffness in your jaw muscles (lockjaw), which can make opening your mouth difficult.
Careful cleaning of wounds, both deep and superficial, can substantially decrease the risk of tetanus.
Tetanus is sometimes found in dust and animal faeces. Infection may occur after minor injury (sometimes unnoticed punctures to the skin that are contaminated with soil, dust or manure) or after major injuries such as open fractures, dirty or deep penetrating wounds, and burns.
Because of vaccination, few people now get tetanus in Australia. Tetanus bacteria live mainly in soil, dust and manure, but can be found anywhere. You can become infected if the bacterium enters your bloodstream through an open wound.
Rust does not cause tetanus. Many people grow up believing they will get tetanus from stepping on a rusty nail. And while a puncture wound from a nail is something to take seriously, you don't get tetanus from rust. Rather, bacteria that live in soil and feces cause tetanus.
You catch it through a cut or wound that becomes infected with tetanus bacteria. The bacteria can get in through even a tiny pinprick or scratch, but deep puncture wounds or cuts – such as those made by nails, knives, or barbed-wire – are especially at risk of infection with tetanus.
Some affected people may experience only pain and tingling at the wound site and some spasms in muscles near the injury site to start with. As things progress, there can be stiffness of the jaw (called lockjaw) and neck muscles, irritability, and difficulty swallowing.
Symptoms of tetanus may not begin to appear until a week after the injury, so as a rule of thumb, try to get the tetanus booster shot within 48 hours of the injury. If tetanus is left untreated, your body could face long-term complications such as airway obstruction, heart failure, muscle damage, and/or brain damage.
What does tetanus look like on the skin? Tetanus infections do not cause a rash and the wound will not show signs of tetanus. The first symptoms can take days, weeks, or even months to appear and usually start at the jaw. From the outside, tetanus may look like muscle tightness in the jaw, neck, and face.
Doctors may use a type of medicine called human tetanus immune globulin (TIG) for someone who has an unclean wound and is not up to date with their tetanus vaccination. These medicines provide immediate protection from the type of bacteria that causes tetanus, but it is not long lasting.
With appropriate immunization and antibody titer, the chances of developing symptoms of tetanus should be very slim, if any. Our case has shown that tetanus can develop in an individual with good titer and can present with a milder form.
Abstract. A follow-up study of 50 patients treated in the tetanus unit of the General Infirmary at Leeds from 1961 to 1977 showed that 29 patients had regained normal health, nine were still improving, but 12 considered that their health had been permanently impaired.
If you have a tetanus-prone wound, additional treatment may be given, even if you've been fully vaccinated. Tetanus-prone wounds are described as: wounds or burns that need surgery, but where surgery cannot be performed within 24 hours.
What are the symptoms of tetanus? A common first sign of tetanus is muscular stiffness in the jaw (lockjaw). Other symptoms include stiffness of the neck, trouble swallowing, painful muscle stiffness all over the body, spasms, sweating, and fever.
Tetanus, also known as lockjaw, is a serious but preventable disease that affects the body's muscles and nerves. It's often referred to as “lockjaw” because it can cause painful spasms and stiffness in your jaw muscles.
Current statistics indicate that mortality in mild and moderate tetanus is approximately 6%; for severe tetanus, it may be as high as 60%. Mortality in the United States resulting from generalized tetanus is 30% overall, 52% in patients older than 60 years, and 13% in patients younger than 60 years.
