This is called localized tetanus. Symptoms may go away without treatment, or they may spread.
Tetanus is not spread from person to person. How long does it take to show signs of tetanus after being exposed? The incubation period varies from 3–21 days, with an average of eight days. The further the injury site is from the central nervous system, the longer the incubation period.
Your doctor will perform a physical exam to check for symptoms of tetanus, such as muscle stiffness and painful spasms. Unlike many other diseases, tetanus is not generally diagnosed through laboratory tests. However, your doctor may still perform lab tests to help rule out diseases with similar symptoms.
People with clean minor wounds need a tetanus booster if their last booster shot was more than 10 years ago. They also include more serious wounds from deep punctures, crushing, and burns. If is more than 5 years since last tetanus shot, get one in the next 72 hours (3 days).
Tetanus became nationally reportable in 1947. Reported tetanus cases have declined more than 95%, and deaths from tetanus have declined more than 99% in the United States since 1947.
Though there's no cure for tetanus, treatment is critical to preventing complications. The death rate is higher for infants who are left untreated, and children who get tetanus may need weeks of hospital care. However, with proper treatment, less than 15 percent of people with tetanus die.
Disease and Vaccine Facts
FACT: You cannot get tetanus from the vaccines. FACT: Tetanus is caused by a toxin produced by bacteria found worldwide in soil, dust, and manure. FACT: Tetanus is not transmitted from one person to another; vaccination provides protection of the vaccinated individual only.Tetanus symptoms include:
- Jaw cramping.
- Sudden, involuntary muscle tightening (muscle spasms) – often in the stomach.
- Painful muscle stiffness all over the body.
- Trouble swallowing.
- Jerking or staring (seizures)
- Headache.
- Fever and sweating.
- Changes in blood pressure and fast heart rate.
You can get it through a cut or other wound. Tetanus bacteria are commonly present in soil, dust, and manure. The tetanus bacteria can infect a person even through a tiny scratch. But you are more likely to get tetanus through deep punctures from wounds created by nails or knives.
The first two shots are given at least four weeks apart, and the third shot is given six to 12 months after the second shot. After the initial tetanus series, booster shots are recommended every 10 years.
Risk Groups
Most reported cases occur in adults. From 2009–2017, more than 60% of the 264 reported cases were among people 20 through 64 years of age. In addition, a quarter of those reported cases were among people 65 years old or older. The risk of death from tetanus is highest among people 65 years old or older.When and for how long is a person able to spread respiratory diphtheria? Untreated patients who are infected with the diphtheria germ may be contagious for up to four weeks. If the patient is treated appropriately, the contagious period can be limited to less than four days.
The global burden of tetanus
In 1990, 314,000 people died due to tetanus while in 2017 there were just slightly over 38,000 deaths — that an 88% reduction.Normally, booster shots are for tetanus and diphtheria alone. Public health authorities also recommend a booster shot if you get a particularly nasty open wound and it's been five years or more since your last tetanus shot.
Common signs and symptoms of tetanus include: Spasms and stiffness in your jaw muscles (trismus) Stiffness of your neck muscles. Difficulty swallowing.
During adulthood, a tetanus-diphtheria booster (Td) is recommended every 10 years for protection against both tetanus and diphtheria. You should seek immediate medical care if you experience any of the following: A wound that is deep, such as a knife wound or animal bite.
You should suspect tetanus if a cut or wound is followed by one or more of these symptoms:
- Stiffness of the neck, jaw, and other muscles, often accompanied by a sneering, grinning expression.
- Difficulty swallowing.
- Fever.
- Sweating.
- Uncontrollable spasms of the jaw, called lockjaw, and neck 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.
Ok, so the legend is true—stepping on a rusty nail DOES have the potential to cause tetanus. Tetanus is caused by bacteria called Clostridium tetani, which is commonly found in soil, dust, and animal feces. The bacterium isn't dangerous in the soil or manure because it can only reproduce in an oxygen-deprived setting.
Vaccination and good wound care are important to help prevent tetanus infection. Doctors can also use a medicine to help prevent tetanus in cases where someone is seriously hurt and doesn't have protection from tetanus vaccines.
There's no cure for tetanus. Treatment consists of wound care, medications to ease symptoms and supportive care.
Symptoms. Common initial symptoms of tetanus are a headache and muscular stiffness in the jaw (lockjaw) followed by stiffness of the neck, difficulty swallowing, hardening of abdominal muscles, spasms, sweating, and fever.
If you're concerned about the wound but have had a vaccine within the past 5 years, you can still go to the hospital to be safe.
If you don't receive proper treatment, the toxin's effect on respiratory muscles can interfere with breathing. If this happens, you may die of suffocation.
Tetanus is not as common as it once was. Still, tetanus patients have only about a 50-50 chance of recovering. Most tetanus deaths occur among infants and the elderly. Everyone who has not had a tetanus shot is at risk to this disease.
