A bacterial disease (fig.1)
that causes involuntary muscular contractions and sometimes
death. Also known as lockjaw.
What is it? (Overview)
Tetanus is a disease that affects the
central nervous system. It is caused by the bacteria Clostridium
tetani. Tetanus bacteria can be found almost everywhere:
in soil, dust, manure, human feces and on pieces of rusty
metal. The bacteria can enter the body through any open
skin wound.
How do I know I have it? (Symptoms
and Diagnosis)
If your child has an open skin wound,
check to see that his immunizations are up-to-date. If his
wound is deep, contact your doctor to see if additional
immunization is needed. Keep an eye on the wound and call
your doctor immediately if it gets red or swollen or if
your child runs a fever.
Signs of tetanus include muscular stiffness
in the jaw (hence the term lockjaw), neck, and abdominal
muscles. Other symptoms include convulsions, rapid heartbeat,
low-grade fever, and in infants difficulty
with sucking.
How can I treat it? (Emergency Treatment)
Clean the wound thoroughly with soap and
water. The doctor will probably give you another tetanus
booster if you havent had one in the last ten years.
If the wound is more severe, and if its been more
than five years since you or your childs last tetanus
shot, its likely that the doctor will also recommend
a booster shot.
How dangerous is it? (Outlook)
Because children are routinely vaccinated
against tetanus, incidence of the disease in this country
is rare. Nonetheless, untreated tetanus is fatal in up to
half of all cases.
How can I prevent it? (Prevention)
The vaccination that immunizes you against
tetanus is called the DTaP vaccine. It also immunizes against
diphtheria and pertussis also known as whooping cough.
Children should get the DTaP vaccine at
2 months, 4 months, 6 months, between 12 and 16 months,
and then again between 4 and 6 years old. At 11 or 12 years
old, children get a booster shot; after that, you only need
a booster shot once every ten years.
Always call your healthcare provider if
you step on a nail or if you get a deep wound when working
or playing outside.
Frequently asked questions (FAQ)
Q: Whats the incubation period
for tetanus?
A: Symptoms can take anywhere from
three days to three weeks to appear. The average amount
of time for the onset of tetanus is 8 to 10 days. Generally,
the more heavily contaminated the wound, the shorter the
incubation period.
Q: If Ive had tetanus once
does that mean Im immune to it in the future?
A: No. And even immunizations dont
work forever. Although children are generally highly immune
to tetanus because they get frequent vaccinations, older
children and adults dont have the same high levels
of antibodies to the disease since they often dont
keep up with their booster shots.
Q: Can the DTaP vaccine cause tetanus?
A: No. The vaccination that children
used to get to prevent tetanus, diphtheria, and pettussis
was called the DTP vaccine. While some children had reactions
to this vaccine, ranging from high fever to severe breathing
difficulties, these reactions were very rare. And the DTaP
vaccine is considered even safer than the DTP vaccine, so
chances are slim that your child will experience any problems
at all. Most reactions such as a fever dont
last for more than three days.
