You probably think of tetanus as something out of a history book or a weirdly specific fear of rusty nails. Honestly, most of us do. We get the shots as kids, maybe grab a booster if we step on something sharp, and otherwise, it’s out of sight, out of mind. But here is the thing: cases of tetanus in the US aren't just a relic of the past. They are happening right now, and the numbers are starting to move in a direction that has public health experts a little on edge.
In 2025, the United States saw a noticeable jump. We went from a decade-long average of about 27 cases a year up to 37. That might sound like a tiny number in a country of 330 million people. But when you realize that tetanus has a fatality rate of about 10% to 11%—even with the best modern ICU care—those 37 cases represent a lot of suffering.
The Reality of Tetanus Today
It’s not just about rusty nails. That is the first big myth to bust. The bacteria, Clostridium tetani, doesn't live on rust; it lives in the soil, dust, and manure. Rust is just a texture that happens to trap dirt. You can get tetanus from a rose thorn, a dog bite, or even a tiny splinter while gardening in your backyard.
Basically, the bacteria produces a toxin that attacks your nervous system. It blocks the signals that tell your muscles to relax. Imagine every muscle in your body seizing up at once, so hard that it can actually snap your own bones. That is what doctors call "opisthotonos," where the back arches so severely only the head and heels touch the ground.
Why Are Cases Rising?
We can't ignore the elephant in the room: vaccination rates are slipping. In places like Florida and Texas, kindergarten DTaP (Diphtheria, Tetanus, and acellular Pertussis) coverage has fallen significantly below the 95% threshold needed for solid community protection. For instance, Broward County in Florida saw rates drop to about 82.2% recently.

When you combine lower immunity with the increasing frequency of natural disasters, you get a "perfect storm" for infection. Think about it. After a hurricane or a massive tornado, thousands of people are out in the mud, clearing debris, handling sharp metal, and getting scratched up. If their boosters aren't up to date, the risk skyrockets.
Real Stories, Real Costs
In 2019, an unvaccinated six-year-old boy in Oregon scratched his forehead while playing. It seemed like nothing. A few days later, his jaw locked shut. He spent 57 days in the hospital, 47 of them in the ICU. The bill? Nearly $1 million.
More recently, in 2025, a nine-year-old in Florida—also unvaccinated—ended up hospitalized for 37 days. These aren't just statistics. These are weeks of intubation, heavy sedation to prevent spasms, and grueling recovery periods. Tetanus is a "medical emergency" in every sense of the word.
Who is Most at Risk?
- The Unvaccinated: This is the obvious one. If you’ve never had the primary series, you have zero protection.
- Seniors: This is the group people often forget. Immunity fades. Many people over 60 haven't had a booster in twenty or thirty years.
- People with Deep Wounds: Puncture wounds are the classic entryway because the bacteria thrives in anaerobic (oxygen-free) environments.
- IV Drug Users: Contaminated needles can introduce the spores directly into the tissue.
How to Tell if It’s Happening
Tetanus doesn't show up the second you get cut. The incubation period is usually around 3 to 21 days. The further the wound is from your central nervous system, the longer it takes to travel.
The first sign is almost always "lockjaw"—that stiffness in the neck and jaw that makes it hard to open your mouth. Then comes the "risus sardonicus," which is a creepy, involuntary permanent grin caused by facial muscle spasms. From there, it moves down the body. Your abdomen gets board-stiff. Swallowing becomes nearly impossible. It is a terrifying progression.
Breaking Down the Prevention Myth
Some people think they can just "wait and see" if a wound looks infected. You can't. Tetanus bacteria don't necessarily cause redness or pus like a staph infection. The wound might look perfectly clean and still be pumping toxin into your nerves.
Also, having tetanus once doesn't make you immune. Unlike the flu or chickenpox, the amount of toxin required to make you sick is actually too small for your immune system to "remember" it. You have to get the vaccine to build that memory.
The Standard Schedule
- Infants/Children: Five doses of DTaP before age 7.
- Adolescents: A Tdap booster around age 11 or 12.
- Adults: A Td or Tdap booster every 10 years.
- Pregnancy: A Tdap dose during the third trimester of every pregnancy to protect the newborn.
Actionable Steps to Stay Safe
Don't panic, but do be proactive. If you can’t remember the last time you had a "tetanus shot," you are probably due.
Check your records. Most pharmacies and primary care doctors can look this up or just give you a "catch-up" dose if you’re unsure. There is no harm in getting an extra booster if you’ve lost track of time.
Clean every wound. Even a minor scrape needs a good scrub with soap and water. If you get a deep puncture—especially from something outdoors—don't just put a Band-Aid on it. Go to urgent care. If it's been more than 5 years since your last shot and the wound is "dirty," they will likely give you a booster right then and there.
Keep a first-aid kit handy. Especially if you live in a disaster-prone area like the Gulf Coast or the Midwest. Having antiseptic and clean bandages on hand can make a difference in the first few minutes after an injury.

Ultimately, tetanus is a disease that we have the tools to beat. We’ve reduced cases by 99% since the 1940s. But that progress only sticks if we stay vigilant about boosters and wound care. It’s a small effort to avoid a million-dollar hospital stay and a life-threatening illness.
