Key facts

Meningitis at a glance.

The essentials, in plain English - what it is, the causes, and why speed matters more than anything else.

  • What it is

    Inflammation of the meninges - the protective membranes around the brain and spinal cord. It is a medical emergency.

  • Bacterial cause

    The most serious form - Neisseria meningitidis, Streptococcus pneumoniae and, rarely, Haemophilus influenzae are the usual culprits.

  • Viral cause

    More common and usually milder - enteroviruses are the leading cause, alongside herpes simplex and varicella.

  • Classic triad

    Fever, neck stiffness and altered consciousness - though this is often incomplete, especially in young children and older adults.

  • Non-blanching rash

    A sign of meningococcal septicaemia - a rash that does not fade under a glass tumbler needs emergency care immediately.

  • Treatment

    Immediate IV antibiotics for suspected bacterial meningitis - do not wait for test results before treating.

Why this guide matters

Minutes matter more than most conditions on this site.

Meningitis is rare, but when it is bacterial it can be devastating without prompt treatment. The three points below shape everything else on this page.

  • Never wait for every symptom

    The classic triad of fever, neck stiffness and altered consciousness is often incomplete - do not wait to see all three before seeking help.

  • Treatment starts before proof

    If bacterial meningitis is suspected, IV antibiotics begin immediately - lumbar puncture and blood results can follow.

  • Vaccination has changed the picture

    MenB, MenACWY, Hib and PCV have cut bacterial meningitis rates sharply in the UK - staying up to date matters at every age.

How the diagnosis is made

From arrival to antibiotics, without delay.

The steps a UK emergency department will normally follow under NICE NG240 - so you know what to expect and why speed is the priority throughout.

  1. 01

    Assessing

    Urgent clinical assessment

    A rapid check for fever, neck stiffness, altered consciousness and any non-blanching rash - treatment is never delayed for this.

  2. 02

    Assessing

    Sepsis and shock screen

    Blood pressure, heart rate, capillary refill and skin colour are checked for signs of meningococcal septicaemia.

  3. 03

    Assessing

    Blood cultures

    Taken before antibiotics if this can be done without delay - but treatment always comes first if bacterial disease is suspected.

  4. 04

    Confirming

    CT head if indicated

    Done first only where there is concern about raised intracranial pressure, before a lumbar puncture is considered.

  5. 05

    Confirming

    Lumbar puncture

    CSF analysis - cell count, protein, glucose, Gram stain, culture and PCR - gives the definitive diagnosis. Avoided if there is raised pressure, a clotting problem or shock.

  6. 06

    Confirming

    PCR and further testing

    Meningococcal and pneumococcal PCR is especially useful when antibiotics have already been started.

  7. 07

    Protecting

    UKHSA notification

    Meningococcal disease is notifiable by law - public health teams act quickly to identify and protect close contacts.

Typical timeline: antibiotics within the hour of suspected bacterial meningitis, not after every test result.

Symptoms

What meningitis actually looks like.

The classic triad, the signs unique to infants, and the rash that should never be ignored.

  • Fever

    Often high and rapid in onset - one part of the classic triad, though it can be absent or low-grade in infants.

  • Neck stiffness

    Difficulty or pain bending the neck forward - a hallmark sign, but frequently absent in young children.

  • Altered consciousness

    Drowsiness, confusion or difficulty rousing - a red flag that always warrants emergency assessment.

  • Severe headache and photophobia

    An unusually intense headache with discomfort in bright light points strongly towards meningitis.

  • Non-blanching rash

    A purpuric rash that does not fade when pressed with a glass - the glass test - signals meningococcal septicaemia.

  • Infant signs

    A bulging fontanelle, high-pitched cry, poor feeding, lethargy and irritability may be the only clues in babies.

  • Kernig's and Brudzinski's signs

    Clinical tests for meningeal irritation - pain on straightening the knee, or involuntary neck-flexion movements.

  • Red flag - sepsis or shock

    Cold hands and feet, mottled skin, rapid breathing or a weak pulse mean immediate emergency transfer.

Treatment

How meningitis is treated in the UK.

Immediate antibiotics for suspected bacterial disease, supportive care for viral meningitis, and public health action to protect close contacts.

  • Pre-hospital benzylpenicillin

    A GP or ambulance crew may give this before transfer if meningococcal disease is suspected - transfer to hospital is never delayed for it.

  • Immediate empirical IV antibiotics

    Ceftriaxone or cefotaxime, started without waiting for investigation results - a genuine medical emergency.

  • Amoxicillin if Listeria risk

    Added for the very young, the elderly, pregnant women and the immunocompromised, who are more susceptible to Listeria meningitis.

  • Adjunctive dexamethasone

    Reduces the risk of neurological complications, particularly in pneumococcal meningitis - a specialist, hospital-led decision.

  • Supportive and intensive care

    Fluid resuscitation and monitoring for raised intracranial pressure, seizures and shock - ICU admission for the most unwell patients.

  • Contact prophylaxis

    Ciprofloxacin or rifampicin offered urgently to close contacts of confirmed meningococcal cases, coordinated through UKHSA.

  • Supportive care for viral disease

    Usually self-limiting - rest, fluids and pain relief, with aciclovir added if herpes simplex encephalitis is a possibility.

  • Long-term follow-up

    Hearing assessment and, in children, developmental review - sensorineural hearing loss is a recognised complication.

Red flags

When to call 999 or go to A&E immediately.

Meningitis is unlike most conditions on this site - these signs mean you should not wait for a GP appointment.

  • Non-blanching rash

    A rash that does not fade under a glass tumbler, with or without fever, needs emergency assessment straight away.

  • Reduced consciousness

    Drowsiness, confusion or difficulty waking someone are emergency signs that should never be watched and waited on.

  • Signs of sepsis or shock

    Cold extremities, mottled skin, a racing heart or rapid breathing point to septicaemia and need immediate emergency care.

  • Infants with poor feeding or a bulging fontanelle

    These subtle signs can be the only clue to meningitis in babies and warrant urgent same-day assessment.

  • Rapid deterioration

    Meningococcal septicaemia can progress from mild symptoms to critical illness within hours - always act on a gut feeling that something is seriously wrong.

  • Immunocompromised or pregnant patients

    Higher risk of Listeria meningitis and a lower threshold for hospital assessment and empirical amoxicillin.

  • Suspected TB meningitis

    Insidious, slowly worsening headache and confusion over days to weeks, particularly in higher-risk groups, needs specialist review.

  • Seizures with fever and headache

    New seizures alongside fever and headache are an emergency presentation requiring immediate hospital care.

  • Close contact of a confirmed case

    Anyone told they are a close contact of confirmed meningococcal disease should take prophylaxis promptly when offered.

Living with it

Recovery, follow-up, and staying protected.

Four things that make the biggest difference - acting fast in the first place, giving recovery time, booking follow-up checks, and knowing where to find support.

A quiet reminder

Trust your instincts - they are usually right.

Parents and carers often notice something is wrong before symptoms are textbook. That instinct is worth acting on.

  1. 01 Act fast

    Never wait on a non-blanching rash

    If the glass test is positive, or you are worried at all, go straight to emergency care - do not wait for every symptom to appear.

  2. 02 Recover

    Give recovery real time

    Fatigue, headaches and low mood are common for weeks after bacterial meningitis - be patient with yourself or your child.

  3. 03 Follow-up

    Book the hearing test

    Sensorineural hearing loss can be silent early on - a formal hearing assessment after bacterial meningitis catches problems early.

  4. 04 Support

    Reach out for support

    Meningitis Now and the Meningitis Research Foundation offer specialist information and support for patients and families.

Frequently asked

Everything we get asked about meningitis.

Quick answers on symptoms, the rash test, vaccination and recovery.

  • What is meningitis?

    Inflammation of the meninges, the membranes covering the brain and spinal cord. It can be caused by bacteria, viruses, fungi or, rarely, tuberculosis, and bacterial meningitis is always a medical emergency.

  • How is bacterial meningitis different from viral meningitis?

    Bacterial meningitis is less common but far more dangerous, needing immediate IV antibiotics. Viral meningitis, usually caused by enteroviruses, is more common and typically settles with supportive care alone.

  • What is the glass test for a rash?

    Press a clear glass firmly against the rash. If the spots do not fade and remain visible through the glass, this is a non-blanching rash and needs emergency medical attention immediately, even without other symptoms.

  • Can meningitis be prevented by vaccination?

    Yes. The UK vaccination programme includes MenB, MenACWY, Hib and PCV, and has significantly reduced rates of bacterial meningitis since introduction. Speak to your GP if you are unsure your vaccinations are up to date.

  • What are the long-term effects of meningitis?

    Most people recover fully, but sensorineural hearing loss, memory or concentration difficulties, and in children, developmental delay, are recognised complications. Follow-up hearing and developmental checks are recommended after bacterial meningitis.

  • Who needs contact prophylaxis?

    Close contacts of someone with confirmed meningococcal disease, such as household members, are usually offered ciprofloxacin or rifampicin. This is arranged urgently through public health teams once a case is confirmed.
