What is Viral 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.
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 echoviruses. These viruses are more common during summer
and fall months. Herpesviruses 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. |
