Tetanus is a serious infection caused by the bacterium Clostridium tetani. These spores live in soil, dust, and manure. When they enter your body through a broken patch of skin, they produce a toxin that attacks your nervous system.
This often leads to painful muscle contractions, particularly in the jaw and neck. Most people know this condition as lockjaw. Because there’s no cure for tetanus once the toxin binds to your nerve endings, prevention is the only reliable way to protect yourself.
At Macomb Medical Clinic in Sterling, MI, Dr. Mark S. Rosenberg, DO, and his team prioritize preventative care to keep patients healthy.
Here’s what they want you to know about tetanus.
Unlike many other diseases, tetanus isn’t spread from person to person. You catch it through environmental exposure. Nearly all cases today occur in people who haven’t stayed current with their 10-year booster shots. When the bacteria enter a wound, they multiply and release a powerful neurotoxin. This toxin causes muscles to tighten and becomes life-threatening if it affects your ability to breathe.
Even with modern medical care, about 10% to 20% of tetanus cases are fatal. Treatment usually involves a long stay in an intensive care unit, where doctors use medications to control muscle spasms and support breathing. Recovery can take weeks or even months as your body grows new nerve endings.
Many people think you can only get tetanus from a rusty nail. While puncture wounds are high risk, any break in the skin can allow bacteria to enter. The bacteria thrive in environments with little to no oxygen. Even minor scrapes can be an entry point if they’re contaminated with dirt or saliva. You should be especially careful with:
If you sustain a deep or dirty wound, check your records immediately. If it’s been more than five years since your last shot, you’ll likely need a booster right away. For clean, minor wounds, the standard 10-year window is usually acceptable.
Adults should receive a booster every 10 years to maintain immunity. If you can’t remember the last time you had a tetanus shot, it’s safer to assume you’re due for one. High vaccination rates are the primary reason tetanus cases have dropped by 95% since the 1940s.
Symptoms of tetanus don't appear immediately. The incubation period is usually between 3 and 21 days. If you start to feel stiffness in your jaw, difficulty swallowing, or sudden muscle spasms after an injury, you need medical attention immediately.
But again, prevention is a simple, quick injection that provides peace of mind for an entire decade. If you’re overdue for your status booster, contact our office in Sterling Heights to request an appointment.
