2. What is Meningitis?
Infection of the fluid in the spinal cord and
the fluid that surrounds the brain
Viral or Bacterial
Etiology is important because of the
seriousness of the illness and the treatment
needed

3. Viral Meningitis
Usually clears up in a week or two with no
specific treatment
Common; rarely serious infection of fluid
in the spinal cord or fluid that surrounds
the brain
Also called aseptic meningitis

4. Causes of Viral Meningitis
Caused by a number of different viruses
mosquito-borne viruses
occasionally seen after strep throat in young
adults
common intestinal viruses account for half of
U.S. cases per year

5. Signs and Symptoms
Usually occur one week after exposure
Fever
Headache
Stiff neck
Tiredness
Rash
Sore Throat
Vomiting

6. Treatment and Prevention
No specific treatment for viral meningitis
Antibiotics do not work on viruses
Pay careful attention to personal hygiene
Good hand-washing helps prevent spread
of infection and viruses

7. Bacterial Meningitis
A serious infection of the fluid of the
spinal cord and the fluid that surrounds the
brain
Results from bacterial invasion of
membrane that covers the brain and spinal
cord (meninges)
Meninges become swollen and inflamed,
leading to classic s/s of meningitis

8. Causes of Bacterial Meningitis
Three common bacteria:
Haemophilus influenza type b (Hib)
Neisseria meningitidis
Causes Meningococcal Meningitis
Streptococcus pneumoniae
Causes Pneumococcal Meningitis

9. How do people get Bacterial
Meningitis?
Bacteria are spread through direct contact
with secretions from the nose or throat of
an infected person
None of the bacteria that cause meningitis
are very contagious
Not spread by casual contact or by simply
breathing the same air where the person
infected has been

10. Signs and Symptoms
Under Age 2
Fever
Headache
Stiff neck
Inactivity
Vomiting
Poor feeding
Seizures
May be hard to detect in
infants
Over age 2
High fever
Headache
Stiff neck
Nausea and vomiting
Sensitivity to light
Confusion
Sleepiness
Petechiae that spreads
rapidly
seizures

11. Diagnosis & Treatment
Diagnosed via lumbar puncture (spinal tap)
Check for bacterial growth in the spinal
fluid
Antibiotic administration based on bacteria
found
Close contacts identified and treated also
Early diagnosis and treatment important

12. Potential Complications
Advanced bacterial meningitis can lead to
brain damage, coma, and death
Survivors can suffer long-term hearing
loss, mental retardation, paralysis, and
seizures

13. Vaccinations
Hib vaccine (3 doses
by 6 months of age
and a booster
between 12-18
months of age)
Meningococcal
vaccine not routinely
given to civilians in
U.S. because most
outbreaks occur in
Africa
Pneumococcal
vaccine ineffective in
persons under age 2
Recommended for all
persons over age 65
with certain medical
problems

14. Travel Precautions
