How can I prevent tetanus?
Tetanus
(lockjaw) infections are very rare in the United States and Canada. You can
help prevent tetanus by having all of the suggested tetanus shots (immunizations).
There are three different types of tetanus shots.
Why is it important to prevent tetanus?
Tetanus is a
disease caused by a
bacterial infection. The tetanus bacteria get in a
wound through a break in the skin or mucous membrane. A cut, puncture wound,
deep scrape, deep burn, or any injury that breaks the skin or mucous membrane
are called wounds.
The bacteria make a toxin, or poison, that
causes severe muscle spasms and seizures. Tetanus is also called "lockjaw"
because muscle spasms in your jaw make it hard to open your mouth. This makes
it hard to swallow or breathe. Tetanus can be very dangerous and can cause
death. The best way to prevent the disease is to have a tetanus shot if you
need one.
How can I tell if I need a tetanus shot?
To decide
if you need a tetanus shot, first decide if the object that caused the wound
was dirty or clean. An object is dirty if it has dirt, soil, spit, or feces on
it. A clean object does not have dirt, soil, spit, or feces on it.
You will need a tetanus shot if:
- Your wound was caused by something that was
clean and your last tetanus shot was longer than 10 years ago.
- Your
wound was caused by something that was dirty and your last tetanus shot was
longer than 5 years ago.
- You are not sure if your wound was caused
by something clean or dirty and your last tetanus shot was longer than 5 years
ago.
- You are not sure when you had your last tetanus
shot.
- You did not get the first series of tetanus shots (primary
vaccination series).
If you need a tetanus shot, call your doctor to arrange for
a shot.
Some people may need tetanus
immune globulin (IG) for a wound that is at high risk
for developing tetanus. The immune globulin is usually only needed if you have
not (or do not know if you have) completed the tetanus primary vaccination
series.
What should I do if I have a reaction to a tetanus shot?
If you have a reaction to a tetanus shot, your symptoms may include
warmth, swelling, and redness at the site where the shot was given. A fever of
up to 100°F (37.8°C) may
occur.
Home treatment can help reduce the discomfort.
