Bacterial Meningitis
WHAT
IS MENINGITIS?
Meningitis is an
inflammation of the covering of the brain and spinal cord. It can be caused by
viruses, parasites, fungi, and bacteria. Viral meningitis is most common and the
least serious. Bacterial meningitis is the most common form of serious bacterial
infection with the potential for serious, long-term complications. It is an
uncommon disease, but requires urgent treatment with antibiotics to prevent
permanent damage or death.
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 a severe headache, high temperature,
vomiting, sensitivity to bright lights, neck stiffness or joint pains, and
drowsiness or confusion. In both children and adults, there may be a rash of
tiny, red-purple spots. These can occur anywhere on the body.
The diagnosis of
bacterial meningitis is based on a combination of symptoms and laboratory
results.
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.
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. The bacteria rarely overcome the body’s immune system
and causes meningitis or another serious illness.
HOW
CAN BACTERIAL MENINGITIS BE PREVENTED?
Do not share food,
drinks, utensils, toothbrushes, or cigarettes. Limit the number of persons you
kiss.
While there are
vaccines for some other strains of bacterial meningitis, they are used only in
special circumstances. These include when there is a disease outbreak in a
community or for people traveling to a country where there is a high risk of
getting the disease. Also, a vaccine is recommended by some groups for college
students, particularly freshmen living in dorms 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
YOU SHOULD DO IF YOU THINK YOU OR A FRIEND MIGHT HAVE BACTERIAL MENINGITIS?
Seek prompt medical
attention.
