Tetanus is extremely rare in the United States and other high-income countries, thanks almost entirely to widespread vaccination. Over the most recent ten-year reporting period (2013 through 2022), the U.S. recorded just 267 total cases and 13 deaths, averaging roughly 27 cases and about 2 deaths per year. Globally, however, the picture is different. Tetanus remains a serious problem in lower-income regions where vaccine access is limited.
Tetanus Cases in the United States
Reported tetanus deaths in the U.S. have dropped by more than 99% since the early 1900s. That decline leveled off around 2000, and the country now sees a consistent average of about two deaths per year. With roughly 27 annual cases in a population of over 330 million, your individual risk is vanishingly small if you’re up to date on vaccinations.
Interestingly, a growing proportion of U.S. tetanus cases now originate from minor wounds rather than major trauma. This likely reflects the fact that deep, dirty wounds tend to get proper medical attention (including a booster shot when needed), while small cuts and scrapes are easy to dismiss. A gardening nick, a small puncture from a rusty nail, or even a splinter can introduce the bacteria if the wound isn’t cleaned and the person’s immunity has lapsed.
Who Gets Tetanus Today
The demographics of tetanus shift depending on where you live. In high-income countries, roughly half of all cases occur in adults over 70. This pattern exists because older adults are the most likely group to have missed boosters or to have immunity that has faded over time. Childhood vaccination programs keep younger age groups well protected, so tetanus in children is nearly unheard of in developed nations.
In lower-income countries, the burden falls hardest on newborns. Neonatal tetanus happens when the umbilical cord stump is contaminated during or after birth, often through unsterile cutting instruments or traditional wound dressings. Newborns born to unvaccinated mothers have no inherited antibody protection, making them especially vulnerable.
The Global Picture
While tetanus is a footnote in U.S. health statistics, it still kills thousands of people worldwide each year, concentrated in regions with limited healthcare infrastructure. In 2018, approximately 25,000 newborns died from neonatal tetanus alone. That number, while devastating, represents a 97% reduction from 1988, when an estimated 787,000 newborns died of the disease within their first month of life. Scaled-up immunization of pregnant women and women of childbearing age drove most of that progress.
As of December 2025, 51 countries have been validated as having eliminated maternal and neonatal tetanus as a public health problem. Eight countries have not yet reached that milestone: Afghanistan, Angola, Central African Republic, Nigeria, Pakistan, Papua New Guinea, Somalia, and Yemen. These are countries where conflict, poverty, or weak health systems make routine vaccination difficult to deliver.
Across all regions, the pattern is consistent: countries with higher development and stronger health systems have dramatically lower tetanus burdens. Low-income regions carry the heaviest toll.
How Dangerous Tetanus Is When It Occurs
Rarity shouldn’t be confused with mildness. Tetanus is a genuinely dangerous infection when it develops. The bacteria produce a toxin that causes severe, uncontrollable muscle spasms, often starting in the jaw (which is why it’s called “lockjaw”) and spreading to the rest of the body. Breathing muscles can be affected, creating a life-threatening emergency.
A large study of 641 patients found that mortality dropped from about 44% to 15% when patients were treated in an intensive care unit rather than managed with standard care alone. That 15% fatality rate, even with modern ICU support, makes tetanus one of the more lethal infections a person can contract. In settings without access to intensive care, the death rate climbs much higher.
Why Vaccination Keeps Numbers So Low
The reason tetanus is so uncommon in vaccinated populations is straightforward: the vaccine works well and protection lasts a long time. A serosurvey of vaccinated adults found that ten years after their last dose, 95% still had antibody levels above the minimum protective threshold. About half of those individuals had levels considered protective for the long term. This is why a booster every ten years is the standard recommendation, though even people slightly overdue are likely still carrying some protection.
Tetanus remains in the first tier of vaccines recommended for all children in the U.S., meaning insurance is required to cover it without cost-sharing. The standard childhood series builds strong baseline immunity, and periodic boosters throughout adulthood maintain it. The system works remarkably well at a population level, which is exactly why U.S. case counts stay in the low double digits each year.
The vulnerability gap appears when people fall out of the routine. Adults who skip boosters for decades, immigrants from countries with weaker vaccination programs, and older adults who may have received fewer doses earlier in life all face higher individual risk. If you can’t remember your last tetanus shot, that’s worth mentioning at your next medical visit, particularly if you spend time gardening, doing construction work, or handling animals.
