What
is Meningitis?
Meningitis is
inflammation of the meninges, the linings surrounding the brain. It can be
caused by bacteria and viruses.
Septicaemia
is blood poisoning caused by bacteria getting into the bloodstream and
multiplying uncontrollably.
Viral meningitis
is more common than bacterial meningitis. It is rarely life threatening,
but it can make people very weak. Viral meningitis can be caused by many
different viruses. Some are spread between people by coughing and
sneezing, or through poor hygiene or sewage-polluted water. Viral
meningitis does not respond to antibiotics, treatment is based on rest and
good nursing care.
Bacterial meningitis
is less common, but it is very serious and needs urgent treatment with
antibiotics. It is mainly caused by the meningococcal bacteria, but can
also be caused by the pneumococcal, Hib and TB bacteria amongst others.
E.coli and group B streptococcal bacteria can also cause meningitis in
newborn babies.
The meningococcus has three main groups,
A, B and C. Group A rarely causes disease in the UK. Of all the cases in
the UK, Group B accounts for 60-70%, Group C accounts for 30-40% and is
the main cause of clusters or outbreaks of the disease. The introduction
of a new C vaccine will significantly reduce its incidence in the UK.
The main bacteria which cause meningitis
are the meningococcal bacteria. These bacteria can also cause septicaemia
(blood poisoning). They enter the bloodstream and travel to the meninges,
when they can cause meningitis.
In some people, the bacteria multiply in
the blood causing blood poisoning. This condition is known as
meningococcal septicaemia. Patients with this condition do not have
meningitis. In most patients, the meningococcal bacteria cause meningitis
and septicaemia at the same time. In this leaflet, we will refer to
meningitis and septicaemia caused by the meningococcal bacteria as
meningococcal disease. Meningococcal disease and other types of meningitis
affect approximately 4,000 people each year in the UK.

How
do you get bacterial meningitis/meningococcal septicaemia?
The bacteria are very common and live
naturally in the back of the nose and throat.
They normally spread between people in close and prolonged contact by
coughing, sneezing and
intimate kissing. They do not live for very long outside the body,
so can’t be picked up from water supplies, swimming pools or buildings.
People of any age can carry the bacteria
for days, weeks or months without becoming ill and carrying the bacteria
can help to make you more immune to meningitis.
Occasionally they overcome the body’s defences and cause meningiti &
meningococcal septicaemia.

Signs and
Symptoms
Meningitis and meningococcal septicaemia
may not always be easy to spot at first, because the symptoms can be
similar to those of flu. They may develop over one or two days, but
sometimes develop in a matter of hours. The incubation period is between
two and ten days.
Symptoms do not appear in any particular
order and some may not appear at all. It is important to remember that
other symptoms may occur.
In babies:
- High temperature, fever, possibly
with cold hands and feet
- Vomiting, or refusing feeds
- High pitched moaning, whimpering cry
- Blank, staring expression
- Pale, blotchy complexion
- Baby may be floppy, may dislike being
handled, be fretful
- Fontanelle (soft spot on their head)
may be tense or bulging
- Difficult to wake or lethargic
In children and adults:
- High temperature, fever, possibly
with cold hands and feet
- Vomiting, sometimes diarrhoea
- Severe headache
- Neck stiffness (unable to touch the
chin to the chest)
- Joint or muscle pains, sometimes
stomach cramps with septicaemia
- Dislike of bright lights
- Drowsiness
- Fitting
- Patient may be confused or
disoriented
Both adults and children may have a rash
Septicaemic rash
Patients with septicaemia will develop a rash which may start anywhere
on the body as a cluster of tiny blood spots, which look like pinpricks in
the skin. If untreated, these blood spots will join to give the appearance
of fresh bruises.
The "glass test" can be used
to see if a rash might be septicaemia. If you press the side of a clear
drinking glass firmly onto the spots or bruises, they will not fade.
NB. In a small number of cases, the rash may disappear at first, but may
later change into one that does not.
Even though the rash can be harder to
see on dark skin. The glass test can still be done. Look for the spots or
bruises on paler parts of the skin, e.g. palms of the hand or soles of the
feet. There is sometimes a rash on the surface of the eye - the part
mainly covered by the eyelid.
Do not wait for a rash.
It may be the last symptom to appear, and in cases of meningitis without
septicaemia may not appear at all.

What
should you do?
- If someone you know is ill and you
suspect meningitis/meningococcal septicamia contact your GP immediately.
- Describe the symptoms carefully,
mention that you think it might be meningitis or meningococcal
septicaemia.
- If your doctor is not available go
straight to the nearest Accident and Emergency Department and insist on
seeing someone.
- If it is meningitis or meningococcal
septicaemia, early treatment with antibiotics is vital.
Meningitis and meningococcal septicaemia
need URGENT medical attention.

Treatment
and Prevention
Viral meningitis does not
respond to antibiotics, treatment is based on rest and good nursing care.
Bacterial meningitis and meningococcal
septicaemia need immediate treatment with antibiotics.
Only people who have come into close
contact with bacterial meningitis and meningococcal septicaemia require
antibiotics. (Close contacts are people living or sleeping in the same
household or who have intimately kissed the patient.) School friends and
work mates of the patient with meningococcal disease are rarely at higher
risk.
Antibiotics are given to kill off any
meningococcal bacteria which may be carried in the back of the nose and
throat. This reduces the risk of passing the bacteria on to others.
Research suggests that not smoking may
reduce the chances of contracting meningitis.
Apart from the vaccines, there is no
known way to protect against meningitis and meningococcal septicaemia.
Vaccines
A new vaccine for Group C
meningococcal disease is available. It will give long-term protection
against this strain and will be given as part of the Childhood
Immunisation Programme, along with the Hib vaccine (which protects against
Haemophilus influenza type B meningitis).
There is also a vaccine against
meningococcal groups A and C, which can be given to people travelling to
areas of the world where these strains occur. It is effective in about 80%
of those who receive it, but is not effective in children under the age of
18 months and only offers protection for about three years.
There is no vaccine against
meningococcus group B, which is still the most common group causing
meningitis. The National Meningitis Trust is funding research looking for
a vaccine against this strain.
