Tetanus after a cut is very uncommon in vaccinated populations like Australia and the US, but remains a risk after deep, dirty, or puncture wounds, especially for those with waning immunity or no vaccination, as the bacteria (Clostridium tetani) lives in soil and can enter any break in the skin, even minor ones. High vaccination rates make it rare, but it's crucial to keep up with boosters (every 10 years) and seek medical care for tetanus-prone wounds like those from rusty nails, thorns, or animal bites.
Wounds can be categorized based on their tetanus exposure risk. Clean and minor wounds don't pose a major risk. Dirty or major wounds pose an increased risk. For example, wounds containing devitalized tissue can allow Clostridium tetani to proliferate.
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. The case-fatality rate in Australia is about 2%.
Symptoms
If you get a cut or other open wound, there are two major ways to protect yourself against tetanus: cleaning the wound and getting vaccinated. First, clean the wound. The bacteria that cause tetanus can get into even tiny breaks in the skin, so it's important to clean even small wounds, such as cuts and scrapes.
"Affected animals may walk stiffly, with the tail held up or extended out behind them." In some cases, tetanus may lead to muscle spasms within the throat or diaphragm (the muscle that controls breathing), making it difficult for cats to breathe. Many patients with generalized tetanus also develop a fever.
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.
If you're eligible, you can get the tetanus vaccine for free under the National Immunisation Program. Talk to our friendly pharmacists to find out more or make your booking below. Making a Tetanus vaccination booking is as easy as 1, 2, 3!
You should get a tetanus shot: Within 48 hours of getting a wound that's deep and/or contaminated with dirt, poop or spit (saliva) — you'll need a booster shot if you haven't had one in the past five years (or can't remember if you have)
Tetanus is rare, but the chances of getting it are higher if: you have not been fully vaccinated (the tetanus vaccine has routinely been given since 1961) you have a large or deep wound. the wound is very dirty or there is something stuck in the wound.
The number of reported tetanus cases decreased after vaccination was introduced in the early 1950s. In 2023, 4 notifications of tetanus were reported, 3 of which occurred in individuals aged 65 and older.
Most healthy children and adults recover from tetanus though the disease causes a serious prolonged illness. Approximately 11 percent of reported cases of tetanus are fatal. In the U.S., where 50 or fewer cases of tetanus occur each year, deaths are more likely to occur in persons 60 years of age and older.
Their analysis shows adults will remain protected against tetanus and diphtheria for at least 30 years without the need for further booster shots, after completing the standard five-dose childhood vaccination series.
However, the bacteria that causes tetanus isn't rare, and its spores are found most commonly in dust, soil, feces and saliva. The tetanus bacteria can infect us with any break of the skin.
How do you prevent tetanus after a cut? Hydrogen peroxide can help sterilize a wound but it's not a substitute for getting a tetanus shot. This is because hydrogen peroxide can't reach all the way into a wound, especially a deep one, which means the tetanus bacteria can still thrive beneath the skin.
For dirty, minor wounds or wounds that penetrate the skin deeply, a booster dose of TT is recommended within 48-72 hours after the injury. For deep or puncture wounds, especially those that are dirty or contaminated, a booster dose of TT is recommended as soon as possible, and ideally within 24 hours after the injury.
All wounds other than clean, minor cuts are considered 'tetanus-prone'. Seek medical advice for dirty wounds or wounds where the skin has been penetrated. First aid treatment should always include cleaning the wound.
Other tetanus symptoms include:
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.
Nearly all cases of tetanus in the United States today are from people who never received a tetanus vaccine or didn't stay up to date on booster doses.
Tetanus bacteria are more likely to infect certain breaks in the skin, including: Wounds contaminated with dirt, feces (poop), or saliva (spit) Puncture wounds (wounds caused by an object, like a nail or needle) Injuries with dead tissue (e.g., burns, crush injuries, frostbite)
There are no laboratory tests that can diagnose or rule out a tetanus diagnosis. Tetanus is a clinical syndrome. Healthcare providers diagnose tetanus based on clinical presentation consistent with tetanus, in the absence of an alternative or more likely cause.
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.
