Meningitis: the signs that must never be ignored
Minutes matter with the bacterial form
Dr. Yanis Kaddour
Infectious disease specialist
In simple terms
How viral and bacterial meningitis differ, the tests that decide, and the prevention available.
What it is, in plain words
Meningitis is inflammation of the membranes surrounding the brain and spinal cord. Viral meningitis is far commoner and usually recovers fully. Bacterial meningitis, especially meningococcal and pneumococcal, can kill within hours and needs antibiotics without waiting for test results.
Signs to look out for
- Severe headache with fever and neck stiffness
- Discomfort looking at bright light and nausea or vomiting
- Drowsiness, confusion, and in severe cases seizures
- A rash of small red or purple spots that does not fade when pressed with a glass, in meningococcal disease
- In babies: high-pitched cry, poor feeding, floppiness, bulging soft spot, unusual irritability
Why it happens
Risk is highest in infants, adolescents and young adults in shared accommodation, older adults, people without a spleen, and those with immune deficiency or recent head injury.
How doctors confirm it
Lumbar puncture examines the spinal fluid and distinguishes bacterial from viral causes; blood cultures and PCR identify the organism. A CT scan is done first only if there are specific neurological signs, and it must not delay antibiotics.
Treatments and solutions
- Immediate intravenous antibiotics, given before or straight after the lumbar puncture when bacterial meningitis is suspected
- Dexamethasone alongside the first antibiotic dose in adults, which reduces hearing loss and other complications
- Intensive care support for shock, seizures and raised pressure inside the skull
- Supportive treatment only for viral meningitis, plus aciclovir if herpes encephalitis is possible
- Preventive antibiotics and vaccination for close contacts of meningococcal cases
Living with it day to day
Vaccines against meningococcal groups, pneumococcus and Haemophilus influenzae type b prevent most bacterial cases; check that adolescents and travellers are up to date.
When to seek medical help
Call emergency services for fever with severe headache and neck stiffness, confusion, seizures, a non-blanching rash, or an unusually drowsy baby.
