Why is meningitis misdiagnosed?
- Early symptoms overlap with common viral illnesses: fever, headache, vomiting, sensitivity to light
- The non-blanching rash may appear late in the illness or not at all in bacterial meningitis without septicaemia
- Children may present with non-specific symptoms: irritability, high-pitched cry, poor feeding, bulging fontanelle in infants
- Clinicians may attribute early symptoms to viral URTI or flu, particularly in winter
What are the classic signs that should prompt urgent investigation?
- Non-blanching petechial or purpuric rash (any rash in a febrile patient that does not fade with a glass test)
- Neck stiffness
- Photophobia
- Severe headache — particularly sudden onset
- Fever with altered consciousness or confusion
- In infants: high-pitched cry, bulging fontanelle, reduced conscious level, temperature instability, mottled skin
NICE guidance specifies that suspected bacterial meningitis or meningococcal septicaemia in children and young people requires immediate hospital admission and urgent treatment with benzylpenicillin if transfer will be delayed.
What are common scenarios in meningitis misdiagnosis claims?
GP attributing symptoms to viral illness
A patient or child presents with fever, headache, and vomiting. The GP diagnoses a viral illness and sends them home. The patient returns hours later with a non-blanching rash or in septic shock. A reasonable GP would have identified the risk of bacterial meningitis and admitted the patient at the first consultation.
A&E discharge before rash appears
A patient presents to A&E with severe headache and fever. Investigation is incomplete. The patient is discharged before the typical rash appears and deteriorates at home.
Failure to perform lumbar puncture
A patient with signs consistent with meningitis is admitted to hospital, but lumbar puncture is not performed within an appropriate time. Diagnosis and targeted antibiotic therapy are delayed.
Neonatal meningitis missed
A newborn with poor feeding, temperature instability, and reduced responsiveness — classic signs of neonatal infection — is not investigated for meningitis. Treatment is delayed and the baby suffers brain damage.
What harm can result from delayed meningitis treatment?
- Death
- Hearing loss or deafness
- Brain damage — from learning difficulties to severe cognitive impairment
- Limb amputation due to tissue death from meningococcal septicaemia
- Scarring from skin necrosis
- Epilepsy
- Vision loss
- Post-meningitis syndrome: fatigue, memory problems, mood changes
What do you need to prove?
- Duty of care — the clinician owed a duty to assess and treat the patient competently.
- Breach of duty — the failure to consider and investigate meningitis fell below the required standard. An independent paediatric or infectious diseases expert will assess this.
- Causation — the delay caused harm that earlier diagnosis and treatment would have prevented or reduced.
- Damage — the resulting disability, amputation, brain injury, deafness, or death.
How much compensation can you claim for meningitis misdiagnosis?
Compensation in serious meningitis negligence claims can be very substantial — particularly where limb amputation has occurred, or where the patient (often a child) has been left with brain damage requiring lifetime care. Total settlements can exceed £1 million in the most serious cases.

Frequently asked questions
Can I claim if my child was sent home from A&E and then diagnosed with meningitis?
Yes — if a competent clinician would have identified the risk of meningitis and admitted or investigated your child at the first presentation, and the delay caused harm.
Can I claim if meningitis was eventually treated but my child lost hearing?
Yes. If the delay in diagnosis caused additional harm — including hearing loss — that earlier treatment would have prevented, a claim for that harm may be available.
Can adults claim for meningitis misdiagnosis?
Yes. The same legal framework applies to all patients. Adult meningitis misdiagnosis claims are as valid as paediatric claims.
