# Tetanus

[Resources](https://www.australiawidefirstaid.com/resources) › [Glossary](https://www.australiawidefirstaid.com/resources/glossary)

## What is Tetanus?

Tetanus is a serious bacterial infection caused by Clostridium tetani, which affects the nervous system and causes muscle stiffness and spasms. It can enter the body through cuts or puncture wounds.

Tetanus, also known as lockjaw, is a serious bacterial infection caused by Clostridium tetani bacteria found in soil, dust, and animal feces. It enters the body through open wounds and produces a toxin that affects the nervous system, leading to muscle stiffness and spasms. Tetanus can be prevented through vaccination with tetanus toxoid-containing vaccines.

In first aid, managing tetanus involves cleaning and treating wounds promptly to prevent bacterial entry and toxin production. Tetanus-prone wounds include those contaminated with soil, feces, or saliva. Administering tetanus toxoid booster vaccinations to individuals with uncertain or incomplete immunization history helps prevent tetanus infection. Early recognition of symptoms such as muscle stiffness, jaw cramping, and difficulty swallowing prompts immediate medical evaluation and treatment.

## Signs of Tetanus

- Painful muscle spasms that can last for several minutes, especially in the face or neck.
- Locked jaw (unable to open mouth).
- Difficulty talking and swallowing.
- Difficulty breathing.
- Rapid heartbeat.
- Fever.

## First Aid for Tetanus

1. Clean the Wound: Thoroughly clean any wounds to prevent infection.
2. Seek Medical Help: Immediate medical attention is necessary for any deep or contaminated wounds.
3. Tetanus Vaccination: Ensure that tetanus vaccinations are up to date. If uncertain, seek a booster shot from a healthcare provider.
