Tetanus
Tetanus is a serious bacterial infection caused by the bacterium Clostridium tetani.
The bacteria forms spores (a hardy form of the bacteria) that can survive and are found within most places in the environment, including soil, dust and manure. The spores develop into bacteria when they enter the body. These bacteria produce toxins that affect the nervous system, subsequently causing muscle spasms, breathing problems and some complications can be fatal.
In most cases, symptoms will occur between 3 days and 3 weeks after infection, with the most common onset after 10 days. However, this can range from 1 day to several months.. Tetanus cannot be transmitted from person to person.
Tetanus is uncommon in Australia because of the widespread use of the tetanus vaccine. Anyone who hasn't been immunised against tetanus is at risk.
Commonly asked questions
Tetanus is a serious bacterial infection caused by a bacterium called Clostridium tetani. The bacteria are found most commonly in soil, dust and manure and can enter the body through breaks in the skin (usually through cuts or puncture wounds caused by contaminated objects).
Tetanus is uncommon in Australia because of the widespread use of the tetanus vaccine. Anyone who hasn't been immunised against tetanus is at risk.
The bacteria are found mostly in the environment (soil, dust and manure) and get in to the body through breaks in the skin. The most common way spores get in to the body is through injuries from contaminated objects. Certain types of skin breaks are more likely to get infected with tetanus bacteria, such as:
- wounds contaminated with dirt, faeces or saliva
- wounds caused by an object puncturing the skin e.g. nails, needles
- burns
- crush injuries
- injuries with dead tissue.
Early signs of tetanus include:
- Muscle spasms or tightness that begin in the jaw and neck
- Inability to open the mouth (lockjaw) swallowing problems
- Breathing difficulties
- Painful convulsions (fits)
- Abnormal heart rhythms.
Occasionally a person may present with a fever and sometimes develop abnormal heart rhythms. Further complications include:
- Pneumonia (infection of the lungs)
- Broken bones from the muscle spasms
- Respiratory failure
- Cardiac arrest.
Tetanus is a vaccine preventable disease. Tetanus vaccine is provided free to:
- Infants and children, as part of the National Immunisation Program at 2, 4, 6, 18 months and 4 years of age
- Adolescents as part of the school immunisation program at 12–13 years of age (the age at which you receive the vaccine varies by state and territory)
Tetanus vaccination is not funded, but recommended for:
- Adults who are 50 years old and above and haven’t had a tetanus booster in the last 10 years
- Travellers going to areas where health services are difficult to access or [del] high-risk areas where there is a high chance of acquiring a tetanus-prone wound
- Individuals who received a primary course of 3 doses as adults, at 10 and 20 years after the primary course
Anyone who has a wound that could be infected with tetanus bacteria should seek medical advice regarding whether they need a tetanus booster if they have not had one in the past 5 years.
