Meningitis is an inflammation of the membranes covering the brain and
spinal cord. There are two types - viral and bacterial. Viral
meningitis isn’t usually very serious and clears up on its own without
treatment. Bacterial meningitis is very serious, and can be fatal if
not treated promptly. There are at least 50 kinds of bacteria that
cause meningitis. The most common ones are:
Meningococcal bacteria: These bacteria now cause most cases of
bacterial meningitis in Britain. Meningococcal infection can lead to
meningitis, septicaemia (blood poisoning) or both. Both diseases are
extremely dangerous. In England & Wales, about 200 people a year die
from meningococcal infection. We will consider meningococcal bacteria
in more detail in a moment.
Pneumococcal bacteria: These are the second biggest cause of
bacterial meningitis in Britain. They more often cause earache,
pneumonia and other less serious illnesses. More on this later.
Haemophilus influenzae b (Hib): These bacteria used to be the most
common cause of meningitis in children under 5, but cases dropped by
90% after the introduction of the Hib vaccine in 1992. However there
has been a small increase of Hib meningitis cases recently. See
chapter 6 for details of the Hib vaccine.
Group B Streptococcal (GBS): These bacteria are the main cause of
meningitis in newborn babies. Up to 90% of babies who get this form of
meningitis survive, and half of those suffer no significant after
effects.
Meningococcal Bacteria
As we’ve already stated, these bacteria are the most common cause of
meningitis in Britain today. There are several types of these
bacteria, but in the UK, there are only 2 major groups that cause the
disease:
Group B: Meningitis caused by this group of bacteria is known more
commonly as meningitis B, and accounts for 60-65% of meningitis cases.
It is the most deadly strain of meningitis, and as yet there is no
vaccine.
Group C: These lead to meningitis C (30-35% of cases). The
meningitis C vaccine was introduced in 1999/2000. Britain is the first
and at present, only country in the world, to vaccinate against
meningitis C.
Another group, Group W135, is on the increase, with over 100 cases per
year in the UK. This coincides with outbreaks amongst pilgrims to
Mecca, and close family contacts in the UK of these pilgrims have
often been affected.
Many of the meningitis-causing bacteria that we have discussed live
harmlessly in the mucous in the back of the nose and throat in 1 in 10
of the population and in up to 1 in 4 young adults in schools,
colleges and military barracks. Most people are not affected by the
bacteria at all and are simply carriers with no symptoms. Indeed these
bacteria may prevent more dangerous types of meningococcal bacteria
getting into the body. However, if the immune system is weak, the
bacteria can pass either into the bloodstream, and cause septicaemia
(blood poisoning), or into the brain causing meningitis. We do not
know what makes certain people susceptible. The bacteria are weak and
don’t live outside the body for more than a few minutes, so meningitis
is only spread by close contact.
Infection by meningococcal bacteria is extremely dangerous. Between
1975 and 1995, almost 1 in 10 of those people who were infected with
the bacteria, died. As we’ve already mentioned, meningococcal bacteria
can cause meningitis, septicaemia or both. Both can be fatal if not
treated immediately. Here we list the symptoms of each disease. If you
suspect your child has either disease, get medical help immediately.
Symptoms of viral meningitis
Viral meningitis is much milder than bacterial meningitis. Symptoms
include fever, headache, vomiting and nausea. It is like a bad case of
flu, and as we’ve said, will clear up on its own but always get a
diagnosis from your doctor.
Symptoms of bacterial meningitis
Bacterial meningitis symptoms come on very suddenly, so prompt action
is vital. First of all your child will have a high fever with
vomiting, a severe headache and a stiff neck. He’ll start shivering,
and have cold hands and feet. He’ll begin rapid breathing, be
intolerant to light, feel drowsy, he’ll have stomach and joint pains
and a rash. In babies you may also see a bulging fontanelle, (the soft
spot on top of his head). His body will be stiff with jerking
movements, and he’ll give a fretful shrill cry if disturbed. He’ll
suffer a loss of appetite and have pale blotchy skin.
Symptoms of septicaemia
If the bacteria enter your child’s bloodstream, they rapidly cause
septicaemia, which is very dangerous. Septicaemia causes the red
blotchy rash under the skin, which can be tested for using the ‘Glass
Test’. Press a glass tumbler onto your child’s skin over the rash. If
the skin remains red despite the pressure, then this is a sure sign of
septicaemia and very fast action must be taken.
What is the treatment for meningitis or septicaemia?
If you suspect your child has meningitis or septicaemia, you must go
to hospital IMMEDIATELY, where antibiotics will normally be given
while the situation is assessed. The earlier the treatment is given
the better the chances of your child’s survival. About one in every
twenty people with meningitis, and one in five people with septicaemia
will die.
