How to Recognise Meningitis in a Child

Meningitis is the diagnosis most parents quietly fear, and the fear is rational — it's one of the few illnesses in childhood that can move from looking-a-bit-off to life-threatening in the space of an afternoon. The good news is that you don't need to memorise a complex differential. You need to know which signs trigger an immediate phone call. For a wider view, see our complete guide to child health.

The Two Things to Hold in Mind

The meninges are the membranes wrapping the brain and spinal cord. Meningitis is inflammation of those membranes. Bacterial meningitis is the dangerous version; viral meningitis is usually milder and self-limiting, though still worth medical assessment.

The bacteria that worry paediatricians most in UK children are Neisseria meningitidis (meningococcus) and Streptococcus pneumoniae (pneumococcus). In newborns, Group B Streptococcus and Listeria are also on the list. Meningococcal disease is particularly time-critical because it often comes with septicaemia — the bloodstream form of the same infection — which is what causes the rash and the rapid deterioration.

Symptoms in Babies Under 12 Months

Babies can't tell you their head hurts. The signs are non-specific, which is exactly why "my baby just doesn't seem right" is taken seriously by NHS 111 and emergency departments. Watch for:

  • A cry that doesn't sound like them. Parents often describe it as high-pitched, moaning, or strangely flat. The phrase "not their cry" comes up again and again in case reports.
  • A bulging fontanelle. Check when the baby is calm and held upright. The soft spot should feel level with the surrounding skull or slightly hollow — if it's tense and domed, that's a red flag.
  • Floppiness. A healthy baby resists when you lift their arm gently and let go. A baby with meningitis often feels limp or "rag-doll."
  • Won't wake properly. Beyond normal sleepy. They don't rouse for a feed, don't focus when you talk to them.
  • Temperature out of range. Fever above 38°C, or — in small babies — a temperature below 36°C. Either is concerning.
  • Skin that looks pale, mottled, or grey-blue. Particularly around the lips and the nailbeds.
  • Refusing feeds in a baby who normally feeds eagerly.
  • Cold hands and feet alongside a hot body — a sign of poor circulation seen in meningococcal sepsis.
  • A non-blanching rash (covered below).

Symptoms in Toddlers (1–3 Years)

By around 18 months, neurological symptoms become more recognisable:

  • High fever with a clear headache (the toddler may hold their head, refuse to lift it from a pillow, or get very distressed when you try to move them)
  • Neck stiffness — they pull away when you flex their chin towards their chest. A formal Kernig's sign (pain when you straighten the knee with the hip flexed) is something the doctor will check.
  • Photophobia — turning away from bright light, asking for the lights off, hiding under blankets
  • Repeated vomiting, often without much warning nausea
  • Seizures — any seizure with fever in this age group needs assessment, but a seizure on top of any of the other signs above is a 999 call
  • Confusion, drowsiness, or behaviour that's just not them
  • A non-blanching rash

The Rash and the Glass Test

The classic rash of meningococcal septicaemia starts as petechiae — pinprick-sized red or purple dots — and progresses to purpura, which look like bruises that appeared from nowhere. The defining feature is that these don't fade under pressure.

To check, press the side of a clear glass firmly against the rash:

  • If the spots disappear under the glass, the rash is blanching. Most childhood rashes blanch and most blanching rashes aren't meningitis — but a blanching rash with the other features above still needs assessment.
  • If the spots stay visible through the glass, this is non-blanching. Blood has leaked out of the small vessels. This is a 999 call. Don't wait, don't drive — phone an ambulance.

The single most important caveat: the rash is a late sign. By the time it appears, the child is already significantly unwell. A child can die of meningococcal disease without ever developing a rash, or develop the rash only an hour before deteriorating. Do not wait for a rash before seeking help if your child looks seriously unwell.

What to Do

If you suspect meningitis or your child looks seriously unwell:
  • Call 999 or take them straight to A&E.
  • If you're talking to NHS 111, say "I'm worried about meningitis" — that phrase routes the call appropriately.
  • Don't wait until morning. Don't wait for the GP to open. The disease moves in hours.
If a non-blanching rash is present:
  • 999 immediately. Tell them about the rash.

While waiting for help: keep the child comfortable, dim the lights if photophobia is an issue, and don't give anything to eat or drink in case they need urgent treatment.

Vaccination — and What It Covers

The UK childhood schedule protects against several causes of bacterial meningitis but not all of them:

  • MenB (Bexsero): 8 weeks, 16 weeks, and 12 months. Covers meningococcal serogroup B — the most common cause of meningococcal disease in young children in the UK.
  • Hib/MenC: 12 months. Covers Haemophilus influenzae type B (a major cause before vaccination) and meningococcal C.
  • Pneumococcal (PCV13): 12 weeks and 12 months. Covers thirteen strains of Streptococcus pneumoniae.
  • MenACWY: offered at 14 years and to first-time university entrants. Covers four meningococcal serogroups.
  • MMR: 12 months and 3 years 4 months. Measles can also cause meningitis as a complication.

No vaccine covers every cause of meningitis, but the schedule has reduced bacterial meningitis in UK children dramatically. Even fully vaccinated children can get meningitis from non-vaccine strains — which is why the symptom signs above remain worth knowing.

Key Takeaways

In babies, the early signs are non-specific: a high-pitched cry that doesn't sound like theirs, floppiness, a bulging fontanelle, refusing feeds, mottled or grey skin. In toddlers, look for fever with headache, neck stiffness, photophobia, and vomiting. The non-blanching rash is a late sign — don't wait for it. If your child looks seriously unwell and you can't put your finger on why, call 999. Meningococcal disease can go from looking off to critical in under six hours.
