MENINGOCOCCAL MENINGITIS FACTS
WHAT IS MENINGITIS?
Meningitis is an inflammation of the lining surrounding the brain
and spinal cord. This condition can be caused by
several different
organisms such as bacteria and viruses.
VIRAL MENINGITIS is more common and
usually occurs in the late Summer and early Fall. Sometimes,
abdominal
discomfort, chest pain, or a rash will be present. The central nervous system
may be involved with
possible alteration of consciousness or paralysis;
however, these more serious conditions are infrequent. Most cases
of viral
meningitis run a short, uneventful course. Since this is a virus (like the
common cold), antibiotics are not
effective. Likewise, persons who have had
contact with viral meningitis patients do not require any treatment.
BACTERIAL MENINGITIS is a rare disease,
but can be very serious and requires treatment with antibiotics. It
can
occur sporadically throughout the year.
One form of bacterial meningitis is MENINGOCOCCAL
MENINGITIS. This form can cause very grave illness.
It requires
early diagnosis and treatment. Untreated meningococcal infection can be fatal.
HOW ARE INDIVIDUALS INFECTED WITH MENINGOCOCCAL
MENINGITIS?
Approximately 5% to 10% of the general population carry the
meningococcal bacteria in the nose and throat in a
harmless state. This
carrier state may last for days or months and seems to give those individuals
who harbor
meningococcus in their upper respiratory tract some protection
from actually developing the disease state.
During epidemics of meningococcal meningitis, the carrier rate may
approach 95%, yet less than 1% may develop
the disease. This low occurrence
of illness after exposure suggests that an individual's health status (the
strength or
weakness of the immune system), rather than bacterial factors,
plays an important determining role.
Meningococcal bacteria cannot usually live for more than a few minutes
outside the body. They are usually not
transmitted in water supplies,
swimming pools, or by routine contact in classrooms, dining rooms, bars,
restrooms,
etc., where an infected individual has been. Roommates, friends,
spouses, and children who are not directly
exposed to an ill meningitis
victim are not at risk.
Persons who have had intimate or direct exposure to a meningococcal
meningitis patient within seven days are at
risk for contracting
meningococcal meningitis and should receive prophylactic medication. Intimate or
direct
exposure includes kissing, sharing eating utensils, or by droplet
contamination from nose, throat, or any secretions or
excretions from the
body of the infected individual.
HOW MANY MENINGOCOCCAL MENINGITIS CASES OCCUR EACH
YEAR?
The annual occurrence rate of meningococcal disease in the United
States is stable at 1 to 3 per 100,000. Average
mortality rates vary
between 2% and 10% with early recognition and treatment being the crucial
variables.
WHAT MAKES MENINGOCOCCAL MENINGITIS SO DANGEROUS?
Meningococcal meningitis can be particularly dangerous for two
fundamental reasons:
1.It is relatively rare. Therefore, we may not consider the possibility of
contracting meningitis and may ignore
early symptoms and signs.
2.It
can be deceptive. A person may experience minor cold symptoms for a few days and
then progress to
severe meningococcal disease in a relatively short period
of time.
In the rare instances when the meningococcus organism invades the
bloodstream, it can be carried to other organs
including the eyes, heart,
lungs, and the central nervous system (brain and spinal cord).
WHAT ARE THE USUAL SYMPTOMS AND SIGNS OF
MENINGOCOCCAL MENINGITIS?
Meningococcal meningitis can cause an individual to become very ill.
Understanding the characteristic
symptoms and signs is critical and could
be lifesaving.
Consult with a physician or go to an emergency room immediately if you
have a fever greater than 101 degree AND
a severe sudden headache
accompanied by mental changes, neck/back stiffness, or rashes*.
* The rashes appear in about 75% of patients and may be quite variable.
They can be as small as 1-2 mm and
appear as tiny red, purple-black spots
or they may be much larger resembling bruises. They are usually found on the
armpits, groin and ankles, and areas where pressure may be applied (e.g.,
underwear and socks).
The majority of patients with a reasonably early diagnosis and treatment
experience complete recovery. In rare
instances, a meningococcal infection
is overwhelming and defies prompt medical treatment.
WHAT IS THE TREATMENT FOR MENINGOCOCCAL MENINGITIS
EXPOSURE?
The use of prophylactic antibiotics such as Rifampin and Ciprofloxacin are
effective in most cases.
WHAT ARE SOME WAYS IN WHICH INDIVIDUALS CAN REDUCE
THEIR RISK OF
CONTRACTING MENINGITIS?
A lifestyle which helps keep the immune system as strong as possible
with a balanced diet, adequate rest and sleep,
appropriate exercise and the
avoidance of excessive stress is very important. Factors, such as avoiding upper
respiratory tract illnesses and inhalation of cigarette smoke, help to protect
from invasive disease. Taking care to
cover your mouth when coughing or
sneezing and frequent hand washing may be preventive as well. Again, research
suggests that the host's health status and ability to resist disease, rather
than bacterial factors, play an important
determining role.
WHAT SHOULD I DO IF I SUSPECT THAT I HAVE ANY OF THE
SIGNS OR SYMPTOMS OF MENINGITIS?
People suspecting that they may have been exposed to Meningitis, displaying the signs or symptoms as described above, or those that have had close bodily contact with anyone diagnosised with the disease, should consult with a physician at their earliest opportunity. Meningitis can be a life-threatening illness that may progress rapidly. Caution is urged and appropriate assessment and treatment recommended.
