Meningitis causes significant and understandable anxiety in parents because it can develop rapidly, is potentially life-threatening, and requires immediate emergency treatment. The good news is that meningitis is rare — made rarer still by the UK's meningitis vaccination programme, which has dramatically reduced bacterial meningitis caused by Meningococcal C, Hib, and Pneumococcal disease. The challenging news is that early meningitis can look like many other illnesses, and the classical signs that everyone knows — the rash and stiff neck — are late features.
Understanding the full range of signs, including the early ones, and knowing what to do allows parents to act quickly when meningitis might be the cause of a child's illness.
Healthbooq provides parents with safety guidance on recognising serious illness in young children, including when emergency action is needed.
What Meningitis Is
Meningitis is inflammation of the meninges — the membranes surrounding the brain and spinal cord. It is most commonly caused by viruses (viral meningitis, which is usually less severe) or bacteria (bacterial meningitis, which is a medical emergency). The most serious bacterial causes in young children in the UK are Neisseria meningitidis (meningococcal disease) and Streptococcus pneumoniae (pneumococcal disease) — both targets of routine childhood vaccinations.
Meningococcal disease in particular can progress from early symptoms to life-threatening illness within hours, which is why rapid recognition is critical.
Early Signs: Before the Rash
The characteristic rash of meningococcal septicaemia — a non-blanching petechial or purpuric rash that does not fade when pressed (the glass test) — is a late sign that appears when bacteria have entered the bloodstream. By this point the child is seriously unwell. Parents who know only to look for the rash may miss the earlier window in which treatment is most effective.
Early signs of meningitis and meningococcal septicaemia include: high fever that comes on suddenly; cold hands and feet despite the fever (a particularly significant early sign); unusual or extreme pallor or skin mottling; severe headache in a child old enough to report it; a high-pitched unusual cry in a baby; refusing feeds; extreme irritability or unusual quietness in a baby; increased sensitivity to bright light; stiff neck (difficulty moving the chin towards the chest — though this can be hard to assess in young babies); and unusual drowsiness or difficulty waking.
In babies, a bulging fontanelle — the soft spot on the top of the head — is an important sign that the pressure inside the skull is raised. The fontanelle normally pulsates gently with heartbeat; a bulge that does not resolve when the baby is held upright and calm is significant.
The Glass Test and the Rash
The glass test: press a clear glass firmly against a rash. If the rash fades under pressure (blanches), it is less likely to be meningococcal rash. If it does not fade (does not blanch) — visible through the glass — this is a medical emergency and 999 should be called immediately.
A non-blanching rash can start as small red or purple pinprick spots (petechiae), which may spread and merge into larger patches (purpura). The rash can appear anywhere on the body and is easier to see on lighter skin; on darker skin it may first be visible on the palms, soles, and inside the lips.
However: waiting for the rash before calling 999 is not the right approach. If a child has a combination of the early signs described above, call 999 regardless of whether a rash is present.
What to Do
Call 999 immediately if a child is showing signs that could be meningitis — especially the combination of high fever with cold extremities, unusual drowsiness, extreme pallor, and any of the other signs described above. Do not attempt to drive to A&E if ambulance is available; paramedics can begin treatment en route. When in doubt, call 999. Meningitis is the condition where acting on a false alarm is far preferable to hesitating.
Key Takeaways
Meningitis — inflammation of the membranes surrounding the brain and spinal cord — is rare but potentially life-threatening, and rapid recognition and emergency treatment are critical to outcomes. The characteristic rash (a non-blanching petechial or purpuric rash, sometimes developing into septicaemia) is a late sign; earlier signs include high fever with cold hands and feet, severe headache, stiff neck, sensitivity to light, unusual drowsiness, and in infants, a bulging fontanelle. Any parent who suspects meningitis should call 999 immediately — this is not a condition for GP appointments or NHS 111 waiting.
