Most parents know to look for the rash. The problem is that the rash is often the last thing to show up — by the time a non-blanching purple spot appears, bacteria are already in the bloodstream and the child is seriously ill. Meningitis is rare in the UK thanks to MenB, MenC, Hib and pneumococcal vaccination, but the children who do get it can deteriorate within hours. The early signs are easier to miss because they look like an ordinary virus, with one or two off notes. This piece walks through what those off notes are, what the glass test does and does not tell you, and when to skip 111 and dial 999. For more on spotting serious illness early, Healthbooq covers the full set of red flags by age.
What Meningitis Actually Is
Meningitis is inflammation of the meninges — the three thin layers wrapping the brain and spinal cord. Viral meningitis is the more common form and most children recover with supportive care. Bacterial meningitis is the medical emergency. In young UK children the main culprits are Neisseria meningitidis (meningococcal disease, especially groups B and W), Streptococcus pneumoniae, and historically Haemophilus influenzae type b before Hib vaccination cut it down by more than 90%.
Meningococcal bacteria can also enter the bloodstream and cause septicaemia, which often runs alongside meningitis and is what produces the famous rash. The combination is what kills, and it can happen fast — published case series describe children going from "off-colour" to critically unwell in 8 to 12 hours.
The Early Signs — Hours Before the Rash
In the first 4 to 8 hours, a child with meningococcal disease often looks like they have a bad virus. The Meningitis Research Foundation's case-series work identified a cluster of early features that appear before the classical signs in roughly half of children:
- Cold hands and feet despite a high fever. This is the single most useful early flag. The child is hot to the touch on the chest and back, but the fingers, toes, and sometimes the nose are cold and pale. It reflects early circulatory shutdown.
- Mottled or unusually pale skin. A blue-grey or marbled pattern on the limbs, or a waxy pallor that doesn't match how the child usually looks.
- Leg pain or refusing to bear weight. Surprisingly common — a toddler who suddenly will not stand, or an older child complaining of severe leg or joint pain, with a fever.
- Refusing feeds, vomiting, or unusual sleepiness. A baby who is hard to wake between feeds, or who feeds and then becomes floppy.
In babies under 12 months specifically, watch for a high-pitched or moaning cry that sounds different from their usual cry, extreme irritability when handled (paradoxically — most ill babies want to be held, but a baby with meningitis often gets worse on cuddling because movement hurts), and a bulging fontanelle. The soft spot on top of the head normally feels flat or slightly sunken when the baby is upright and calm; a tense, dome-like bulge that does not soften when they sit up is significant.
The Classical Signs
The triad most parents have heard of — neck stiffness, severe headache, photophobia — is real but appears later, and is unreliable in babies and toddlers because they cannot describe a headache and their necks are short and floppy by nature. In a child over about 2, watch for:
- Refusing to bring the chin to the chest, or crying when you try to bend the neck forward.
- Burying the face in a pillow or covering the eyes when a light is turned on.
- Holding still, irritable when moved.
- Confusion, slurred speech, or unusual drowsiness.
The Rash and the Glass Test
The meningococcal septicaemia rash is non-blanching — it does not fade when pressed. Press the side of a clear drinking glass firmly onto the spots. If the marks stay visible through the glass, that is a 999 call right now.
The rash starts as tiny red or purple pinprick spots (petechiae), often on the trunk first, and can spread and merge into larger purple bruise-like patches (purpura) within hours. On Black and brown skin it is harder to see on the trunk; check the palms, soles, inside the lower eyelids, and inside the lips first, where it shows up earlier.
Two things parents need to know about the glass test:
- A blanching rash does not rule out meningitis. Many children with meningococcal disease have a non-specific blotchy rash early on that does fade under pressure. The rash evolves.
- Do not wait for the rash before calling. By the time it appears, the child is often hours into septicaemia. If the early signs are there, call 999 with no rash.
When to Call 999 vs 111
Call 999 for:
- A baby or child with fever plus cold extremities, mottled skin, or unusual drowsiness.
- A bulging fontanelle in a baby.
- Any non-blanching rash, regardless of how well the child otherwise seems.
- Sudden severe headache with a stiff neck and photophobia.
- A child who is hard to rouse, floppy, or having a seizure.
- That gut feeling that something is seriously wrong — parental instinct is in the NICE traffic-light guidance for a reason.
Use 111 only if the child is alert, feeding, and the symptoms are mild and isolated — and even then, ring back or escalate to 999 if anything changes. Meningitis is one of the few conditions where overcalling is the right call. A&E doctors and ambulance crews would rather see ten well children than miss one septic one.
While you wait for the ambulance, keep the child lying on their side if they are sleepy or vomiting, do not give food or drink in case they need urgent surgery or sedation, and take a phone photo of any rash so you can show how it has changed.
After the Vaccines, Do I Still Need to Worry?
Yes, but less. The MenB vaccine added to the UK routine schedule in 2015 has cut MenB cases in vaccinated infants by around 75% in published Public Health England data. MenC, Hib, and pneumococcal vaccines have all but eliminated their respective bacterial meningitides in young children. What remains: MenB cases in older infants and toddlers, MenW (rising in teens), viral meningitis, and pneumococcal disease in unvaccinated or partially-vaccinated children. The schedule does not cover every strain, and no vaccine is 100% — which is why recognising the symptoms still matters.
Key Takeaways
Meningococcal disease can go from mild-looking to life-threatening in under 12 hours, so the early signs matter more than the famous ones. Cold hands and feet alongside a high fever, mottled or unusually pale skin, refusing feeds, a high-pitched cry, a bulging fontanelle in a baby, or sudden floppy drowsiness all warrant a 999 call — before any rash appears. The non-blanching rash is a late sign, and a normal glass test does not rule meningitis out. When in doubt, call 999, not 111.
