Meningitis Meningitis is an inflammation of the
membranes that cover the brain and spinal cord. The cause of
this inflammation is infection with either bacteria or
viruses. Meningitis caused by a bacterial
infection (sometimes called spinal meningitis) is one of the
most serious types, sometimes leading to permanent brain
damage or even death. Bacterial meningitis is most commonly
caused by bacteria called Neisseria meningitidis
(meningococcal meningitis), Streptococcus pneumoniae, or
Haemophilus influenzae serotype b (H. flu meningitis). These
bacteria are carried in the upper back part of the throat of
an infected person and are spread either through the air
(when the person coughs or sneezes organisms into the air)
or by direct contact with secretions. Transmission usually
occurs only after very close contact with the infected
person. Symptoms of bacterial meningitis
include sudden onset of fever, headache, neck pain or
stiffness, vomiting (often without abdominal complaints),
and irritability. These symptoms may quickly progress to
decreased consciousness (difficulty in being aroused),
convulsions, and death. For this reason, if any child
displays symptoms of possible meningitis, he or she should
receive medical care immediately. Meningitis caused by Haemophilus
influenza serotype b (Hib) can be prevented with Hib
vaccine, which is part of routine childhood immunizations.
Some cases of meningococcal meningitis can also be prevented
by vaccine. However, this vaccine is not used routinely, and
usually only during outbreaks or in high risk
children. Children with bacterial meningitis are
almost always hospitalized. COMMON
