Texas
Education Agency (TEA) Awareness Release Regarding Bacterial Meningitis
What is meningitis?
Meningitis is an inflammation of the covering of the brain and spinal
cord—also called the meninges. It can be caused by viruses, parasites,
fungi, and bacteria. Viral (aseptic) meningitis is common; most people
recover fully. Medical management of viral meningitis consists of
supportive treatment and there is usually no indication for the use of
antibiotics. Parasitic and fungal meningitis are very rare. Bacterial
meningitis is very serious and may involve complicated medical,
surgical, pharmaceutical, and life support management.
There are two common types of bacteria that
cause meningitis:
Strep pneumoniae causes pneumococcal
meningitis; there are over 80 subtypes that cause illness
Neisseria meningitidis—meningococcal
meningitis; there are 5 subtypes that cause serious illness— A, B, C, Y,
W-135
What are the symptoms?
Someone with meningitis will become very ill. The illness may develop
over one or two days, but it can also rapidly progress in a matter of
hours. Not everyone with meningitis will have the same symptoms.
Children (over 1 year old) and adults with
meningitis may have:
Severe headache
High temperature
Vomiting
Sensitivity to bright lights
Neck stiffness, joint pains
Drowsiness or confusion
*In both children and adults, there may be a rash of tiny, red-purple
spots or bruises caused by bleeding under the skin. These can occur
anywhere on the body. They are a sign of blood poisoning (septicemia),
which sometimes happens with meningitis, particularly the meningococcal
strain.
How serious is bacterial meningitis?
If it is diagnosed early and treated promptly, the majority of people
make a complete recovery. In some cases it can be fatal or a person may
be left with a permanent disability, such as deafness, blindness,
amputations or brain damage (resulting in mental retardation or
paralysis) even with prompt treatment.
How is bacterial meningitis spread?
Fortunately, none of the bacteria that cause meningitis are as
contagious as diseases like the common cold or the flu, and they are not
spread by casual contact or by simply breathing the air where a person
with meningitis has been. The germs live naturally in the back of our
noses and throats, but they do not live for long outside the body. They
are spread when people exchange saliva (such as by kissing; sharing
drinking containers, utensils, or cigarettes).
The germ does not cause meningitis in most
people. Instead, most people become carriers of the germ for days, weeks
or even months. Being a carrier helps to stimulate your body’s natural
defense system. The bacteria rarely overcome the body’s immune system
and causes meningitis or another serious illness.
What is the risk of getting bacterial
meningitis?
The risk of getting bacterial meningitis in all age groups is about 2.4
cases per 100,000 population per year. However, the highest risk group
for the most serious form of the disease, meningococcal meningitis, is
highest among children 2 to 18 years old.
How is bacterial meningitis diagnosed?
The diagnosis is usually based on a combination of clinical symptoms and
laboratory results from spinal fluid and blood. Spinal fluid is obtained
by a lumbar puncture (spinal tap).
How can bacterial meningitis be prevented?
Do not share food, drinks, utensils, toothbrushes, or cigarettes. Limit
the number of persons you kiss.
Vaccines against pneumococcal disease are
recommended both for young children and adults over 64. A vaccine
against four meningococcal serogroups (A, C, Y, W-135) is available.
These four groups cause the majority of meningococcal cases in the
United States. This vaccine is recommended by some groups for college
students, particularly freshmen living in forms or residence halls. The
vaccine is safe and effective (85-90%). It can cause mild side effects,
such as redness and pain at the injection site lasting up to two days.
Immunity develops within 7 to 10 days after the vaccine is given and
lasts for up to 5 years.
What should you do if you think you or a
friend might have bacterial meningitis?
Seek prompt medical attention.
For more information
Your school nurse, family doctor, and the staff at your local or
regional health department office are excellent sources for information
on all communicable diseases. You may also call your local health
department or Regional Texas Department of Health office to ask about
meningococcal vaccine. Additional information may also be found at the
web sites for the Centers for disease Control and Prevention:
