how do you get tetanus

Updated January 12, 2021

As you spend time in the great outdoors, you should be aware of the risks of contracting tetanus.

Tetanus is a dangerous nerve condition caused by the bacteria Clostridium tetani.

You can get a tetanus infection when certain substances — such as soil or fecal matter — enter cuts and scrapes on your body. This can cause problems with movement and brain and nervous system functions.

Tetanus Causes

Many people associate tetanus with rusty objects — like stepping on a rusty nail or cutting yourself on a sharp piece of metal.

But the bacterium actually lives in soil, dust, and manure. Any activity that brings you in contact with these substances carries a risk of tetanus infection.

Even very small open wounds — as small as a needle prick — could cause tetanus, though it’s more likely with large cuts.

Other common ways you can get a tetanus infection include:

  • Animal bites or scratches
  • Bug bites
  • Splinters
  • Deep burns
  • Body piercings and tattoos

Your risk of tetanus infection increases if the puncture becomes dirty.

Keep in mind — you can’t get tetanus from another person, so there’s no risk of transmitting the disease to someone else.

Who’s at Risk?

The best way to lower your risk of contracting tetanus is by staying up-to-date on your tetanus vaccine, which requires a booster shot every ten years. Everyone who has not had their tetanus vaccine is vulnerable to this condition.

The following factors can put you at a higher risk of getting tetanus if you’re unvaccinated:

  • Occupations such as farming, firefighting, and construction
  • Old age
  • Outdoor hobbies such as hiking, gardening, or camping
  • History of diabetes or immunosuppression

Tetanus Symptoms

Tetanus impacts the nerves that control your muscles, so you may experience difficulty swallowing, or feel stiffness in your jaw, abdomen, chest, back, and neck. Here are some of the most common symptoms of tetanus:

  • Muscles spasming
  • Stiff feeling or achey muscles
  • Vertigo
  • Involuntary eye movement or blurred vision
  • Sudden weakness in the arms or legs
  • Double vision
  • Lockjaw

You may be familiar with tetanus’ nickname lockjaw, which stems from the painful muscle contractions in the jaw and neck that the condition can create.

If you start feeling muscle stiffness or having trouble breathing, seek emergency medical care.

How to Prevent Tetanus

If it’s been more than 10 years since you last had a tetanus shot and you cut yourself with metal, find immediate medical attention.

For those who have recently had a vaccine, such as the DTaP or TD boosters:

  • Clean the wound with water and soap, if available.
  • Put on antibiotic ointment.
  • Place a bandage over the wound to prevent dirt or other bacteria from entering.

If your cut is especially deep or you believe you’re at an increased risk of contracting tetanus, contact your doctor right away.

Tetanus Treatment

Tetanus can be treated with a variety of therapies and medications, and your doctor will choose a treatment method based on the severity of your symptoms.

Some common treatment options for tetanus include:

  • Cleaning the infected wound to cleanout the source of the bacteria
  • Antibiotics
  • Muscle relaxers to reduce muscle spasms
  • A tetanus vaccine may be given in coordination with treatment
