New
Meningitis Case, Total is Now
Four
The total cases of meningitis is
now at four, the latest case is
of Carolina Araya, who was
admitted to the Hospital México
yesterday.
Dr. Armando Villalobos confirmed
the latest case of the woman who
had gone to the emergency room
on Tuesday night and was moved
to the Intensive Care ward
yesterday.
Araya, who is from Heredia, is a
student at the Academia Nacional
de Policía (National Police
Academy) in San José. All 1.200
students, staff and personnel at
the Academy were given yesterday
an antibiotic to ward of the
illness.
Tuesday it was announced that
Kaine Sandoval, who is an
employee of Royal Scientific,
located in Heredia, where the
first cases of the Meningitis
were discovered, is being kept
in isolation at the San Vicente
de Paúl hospital in Heredia.
Jeremías Bravo, of Heredia, and
José Carranza, of Alajuela died
of bacterial meningitis during
the past two weeks.
Health authorities are ruling
out that there is an outbreak of
meningitis.
Meningitis is an inflammation of
the meninges, the membranes that
cover the brain and spinal cord.
The inflammation is usually
caused by bacteria or viruses
(viral meningitis is also called
aseptic meningitis).
Many of the bacteria or viruses
that can cause meningitis are
fairly common and are more often
associated with other everyday
illnesses. Sometimes, however,
they spread to the meninges from
an infection in another part of
the body. The infection can
start anywhere, including in the
skin, gastrointestinal tract, or
urinary system, but the most
common source is the respiratory
tract.
From there the microorganisms
can enter the bloodstream,
travel through the body, and
enter the central nervous
system. In some cases of
bacterial meningitis, the
bacteria spread directly to the
meninges from a severe nearby
infection, such as a serious ear
infection (otitis media) or
nasal sinus infection
(sinusitis). Bacteria may also
enter the central nervous system
after severe head trauma or head
surgery.
Bacterial meningitis is less
common than viral meningitis but
is usually much more serious and
can be life-threatening if not
treated promptly.
Bacterial meningitis occurs in
people of all ages but is more
common in the very young
(infants and young children) and
the elderly (people above age
60).
Bacterial meningitis
A variety of organisms can
cause bacterial meningitis, a
serious form that can be fatal,
especially in children. Symptoms
include high fever, headache,
chills, vomiting, stiff neck or
back, and confusion, sometimes
accompanied by a purplish rash.
Serious cases can quickly lead
to delirium, coma, or
convulsions. It is spread by
oral or nasal secretions.
The leading cause of bacterial
meningitis is the ill-named
bacterium Haemophilus influenzae
b (Hib), originally thought to
be an influenza virus. It
commonly affects infants and
children. The second most common
bacterial cause of meningitis is
Neisseria meningitidis (meningococcus).
Meningococcal meningitis affects
people of all ages and tends to
occur in epidemics, especially
among those who live in crowded
conditions. An outbreak in the
slums of Brazil in 1974–75
killed 11,000 people and left
over 75,000 with permanent
neurological complications. In
1996, an epidemic centered in
the Sahel region of W Africa
killed 16,000. In the United
States it is seen most often in
children and teens.
Strepococcus pneumoniae, also
referred to as pneumococcus, is
another cause of serious
meningitis cases. It is the most
common cause of meningitis in
adults. It often accompanies
pneumococcus infections in other
parts of the body, such as the
ear or sinuses. Other bacterial
causes of meningitis include
tuberculosis, leptospirosis, and
Lyme disease.
Bacterial meningitis calls for
emergency medical care and the
administration of antibiotics.
Close contacts of patients with
bacterial meningitis may receive
prophylactic antibiotics, such
as rifampin.
Definitive diagnosis can be made
by laboratory tests of
cerebrospinal fluid obtained by
a lumbar puncture (spinal tap).
Twenty to thirty percent of
children who survive bacterial
meningitis sustain permanent
neurological damage such as
deafness, mental retardation, or
convulsions. Since the late
1980s, routine vaccination of
young children against Hib has
virtually eliminated Hib disease
in the United States. Routine
vaccination against
meningococcal meningitis is
recommended for pre-adolescents,
and vaccination is also
recommended for persons in the
military or traveling to parts
of Africa where the disease is
endemic. The meningococcal
vaccine does not provide
protection against all
meningococcus strains.
