WHAT IS MENINGOCOCCAL MENINGITIS?
Meningococcal disease is a severe bacterial infection of the
bloodstream or meninges (a thin lining covering the brain and spinal
cord). It is a relatively rare disease and usually occurs as a single
isolated event. Clusters of cases or outbreaks are rare in the United
States.
HOW IS THE GERM MENINGOCOCCUS SPREAD?
Meningococcal disease is transmitted through the air via droplets of
respiratory secretions and direct contact with an infected person.
Direct contact, for these purposes, is defined as oral contact with
shared items such as cigarettes or drinking glasses or through intimate
contact such as kissing. Although anyone can come in contact with the
bacteria that causes meningococcal disease, data also indicates certain
social behaviors, such as exposure to passive and active smoking, bar
patronage, and excessive alcohol consumption, may put students at
increased risk for the disease. Patients with respiratory infections,
compromised immunity, those in close contact to a known case, and
travelers to endemic areas of the world are also at increased risk.
WHAT ARE THE SYMPTOMS?
The early symptoms usually associated with meningococcal disease
include fever, severe headache, stiff neck, rash, nausea, vomiting, and
lethargy, and may resemble the flu. Because the disease progresses
rapidly, often in as little as 12 hours, students are urged to seek
medical care immediately if they experience two or more of these
symptoms concurrently. The disease is occasionally fatal.
HOW SOON DO THE SYMPTOMS APPEAR?
The symptoms may appear two to 10 days after exposure, but usually
within five days.
WHAT IS THE TREATMENT FOR MENINGOCOCCAL DISEASE?
Antibiotics, such as penicillin G or ceftriaxone, can be used to treat
people with meningococcal disease.
SHOULD PEOPLE WHO HAVE BEEN IN CONTACT WITH A DIAGNOSED CASE OF
MENINGOCOCCAL MENINGITIS BE TREATED?
Only people who have been in close contact (household members, intimate
contacts, health care personnel performing mouth-to-mouth
resuscitation, day care center playmates, etc.) need to be considered
for preventive treatment. Such people are usually advised to obtain a
prescription for a special antibiotic (either rifampin, ciprofloxacin
or ceftriaxone) from their physician. Casual contact as might occur in
a regular classroom, office or factory setting is not usually
significant enough to cause concern.
IS THERE A VACCINE TO PREVENT MENINGOCOCCAL MENINGITIS?
Presently, there is a vaccine that will protect against some of the
strains of meningococcus. It is recommended in outbreak situations, and
for those traveling to areas of the world where high rates of the
disease are known to occur. For some college students, such as freshman
living in dormitories, there is a modestly increased risk of
meningococcal disease; students and parents should be educated about
meningococcal disease and the availability of a safe and effective
vaccine.
HOW EFFECTIVE IS THE VACCINE?
The meningococcal vaccine has been shown to provide protection against
the most common strains of the disease, including serogroups A, C, Y
and W-135. The vaccine has shown to be 85 to 100 percent effective in
serogroups A and C in older children and adults.
IS THE VACCINE SAFE?
ARE THERE ADVERSE SIDE EFFECTS TO THE VACCINE? The vaccine is very safe
and adverse reactions are mild and infrequent, consisting primarily of
redness and pain at the site of injection lasting up to two days.
WHAT IS THE DURATION OF PROTECTION?
The duration of the meningococcal vaccine’s efficacy is approximately
three to five years.
