Tetanus is caused by the bacteria Clostridium tetani, which is found in soil and animal manure.
What is Tetanus?
Tetanus is a serious bacterial disease that affects the nervous system, leading to painful muscle contractions. It is commonly known as "Lockjaw" because it often causes the jaw muscles to lock shut.
Key Fact: Unlike most vaccine-preventable diseases, Tetanus is not contagious from person to person. You get it from the environment.

🛑 MYTH BUSTER: The "Rusty Nail."
Myth: "You only get tetanus from rusty nails."
Fact: Rust itself does not cause tetanus. The bacteria live in soil, dust, and manure. A rusty nail is dangerous only because it has likely been outside in the dirt for a long time. You can get tetanus from a clean nail, a gardening tool, or even a rose thorn if it has soil on it.

Symptoms
Symptoms appear anywhere from a few days to weeks after the injury (average 7-8 days). They usually start at the head and move down.
- Lockjaw (Trismus): Spasms and stiffness in jaw muscles.
- Sardonic Smile: Facial spasms that cause a strange, fixed grin.
- Neck Stiffness & Difficulty Swallowing.
- Opisthotonos: Severe, painful body spasms that can arch the back uncontrollably. These can be strong enough to break bones.
⚠️ WHEN TO SEE A DOCTOR
See a doctor immediately if you have a deep or dirty wound and:
See a doctor immediately if you have a deep or dirty wound and:
- You haven't had a tetanus shot in the last 5 years.
- You are unsure of your vaccination status.
How do you get it?
The bacteria enter the body through broken skin. Common entry points include:
- Puncture wounds (nails, splinters, piercings).
- Gunshot wounds or crush injuries.
- Burns or surgical wounds.
- Infected foot ulcers (common in diabetics).
Treatment
There is no cure for tetanus once the toxin binds to nerve endings. Treatment focuses on managing symptoms while the body heals (which takes months).
- Tetanus Antitoxin (TIG): Can neutralize toxin that hasn't yet bonded to nerves.
- Sedatives: To control severe muscle spasms.
- Ventilator Support: Often required because muscle spasms can stop breathing.
Prevention: The Vaccine
Tetanus is 100% preventable with vaccination.
- DTaP: Given to young children in a series of 5 shots.
- Tdap: The booster shot given to pre-teens and adults (also protects against Pertussis/Whooping Cough).
- The "10-Year Rule": Adults should get a Td booster every 10 years.
Immediate Wound Care
If you step on a nail or get a dirty cut, do this immediately:
- Control Bleeding: Apply direct pressure.
- Cleanse: Rinse thoroughly with clean running water to flush out bacteria. Wash the area with soap.
- Antibiotic Cream: Apply a thin layer of Neosporin or Polysporin to discourage bacterial growth.
- Cover: Bandage the wound to keep dirt out.
- Seek Medical Help: If the wound is deep or contains debris that you can't remove.
