Welcome to Our Informational Website
on Viral Meningitis
Viral meningitis, also known as aseptic
meningitis is an infection of the brain covering
and spinal cord caused by a virus.
Viral meningitis cases may happen at any time
of the year but ViralMenigitis occurs more frequently in the
late summer or early fall.
Viral meningitis can be caused by different
viruses and is usually not as serious as bacterial meningitis.
Viral meningitis is fairly easily curable and treatable if caught early and well diagnosed by your doctor.
Meningitis is an infection of the fluid of a person's spinal
cord and the fluid that surrounds the brain. People sometimes
refer to it as spinal meningitis.
Is it Viral Meningitis or Bacterial
Meningitis?
Spinal meningitis is typically caused by a viral infection or bacterial infection.
Knowing whether spinal meningitis is caused by a virus or bacteria
can be quite important since its severity and treatment options
differ. Viral meningitis is generally less severe and resolves
without specific treatment, while bacterial meningitis can
be quite severe and may result in brain damage, hearing loss,
or learning disability. It also is important to know which
type of bacteria is causing the meningitis because antibiotics
can prevent some types from spreading and infecting other
people.
FAQs on Viral ("Aseptic") Meningitis
Is viral meningitis a serious disease?
Viral ("aseptic") meningitis is serious but rarely
fatal in persons with normal immune systems. Usually, the
symptoms last from 7 to 10 days and the patient recovers completely.
Bacterial meningitis, on the other hand, can be very serious
and result in disability or death if not treated promptly.
Often, the symptoms of viral meningitis and bacterial meningitis
are the same. For this reason, if you think you or your child
has meningitis, see your doctor as soon as possible.
Who gets viral meningitis?
Anyone can get viral meningitis but it occurs most often
in children.
What causes viral meningitis?
Many different viruses can cause meningitis. About
90% of cases of viral meningitis are caused by members of
a group of viruses known as enteroviruses, such as coxsackieviruses
and echo viruses. These viruses are more common during summer
and fall months. Herpes viruses and the mumps virus can also
cause viral meningitis.
How is viral meningitis diagnosed?
Viral meningitis is usually diagnosed by laboratory
tests of spinal fluid obtained with a spinal tap. The specific
cause of viral meningitis can be determined by tests that
identify the virus in specimens collected from the patient,
but these tests are rarely done.
How is viral meningitis treated?
No specific treatment for viral meningitis exists
at this time. Most patients completely recover on their own.
Doctors often will recommend bed rest, plenty of fluids, and
medicine to relieve fever and headache.
How is the virus spread?
Enteroviruses, the most common cause of viral meningitis,
are most often spread through direct contact with respiratory
secretions (e.g., saliva, sputum, or nasal mucus) of an infected
person. This usually happens by shaking hands with an infected
person or touching something they have handled, and then rubbing
your own nose or mouth. The virus can also be found in the
stool of persons who are infected. The virus is spread through
this route mainly among small children who are not yet toilet
trained. It can also be spread this way to adults changing
the diapers of an infected infant. The incubation period for
enteroviruses is usually between 3 and 7 days from the time
you are infected until you develop symptoms. You can usually
spread the virus to someone else beginning about 3 days after
you are infected until about 10 days after you develop symptoms.
Can I get viral meningitis if I’m
around someone who has it?
The viruses that cause viral meningitis are contagious. Enteroviruses,
for example, are very common during the summer and early fall,
and many people are exposed to them. However, most infected
persons either have no symptoms or develop only a cold or
rash with low-grade fever. Only a small proportion of infected
persons actually develop meningitis. Therefore, if you are
around someone who has viral meningitis, you have a moderate
chance of becoming infected, but a very small chance of developing
meningitis.
How can I reduce my chances of becoming
infected?
Because most persons who are infected with enteroviruses
do not become sick, it can be difficult to prevent the spread
of the virus. However, adhering to good personal hygiene can
help to reduce your chances of becoming infected. If you are
in contact with someone who has viral meningitis, the most
effective method of prevention is to wash your hands thoroughly
and often. Also, cleaning contaminated surfaces
and soiled articles first with soap and water, and then disinfecting
them with a dilute solution of chlorine-containing bleach
(made by mixing approximately ¼ cup of bleach with
1 gallon of water) can be a very effective way to inactivate
the virus, especially in institutional settings such as child
care centers. (See more about cleaning and disinfecting in
general in CDC's Prevention Resources).
What are the symptoms?
The symptoms may include fever, headache, stiff neck and
fatigue. Rash, sore throat and intestinal symptoms may also
occur.
How soon do symptoms appear?
Symptoms generally appear within 1-week of exposure.
Is a person with viral meningitis contagious?
Some of the enteroviruses that cause viral meningitis are
contagious while others, such as mosquito-borne viruses, cannot
be spread from person to person. Fortunately, most people
exposed to these viruses experience mild or no symptoms. Most
people are exposed to these viruses at some time in their
lives, but few actually develop meningitis.
Should a person with a viral meningitis
be isolated?
Strict isolation is not necessary for a person with viral
meningitis. Since most cases of spinal meningitis and viral meningitis are due to
viruses that may be passed in the stool, people diagnosed
should be instructed to wash their hands after using the bathroom.
