What is Meningitis?
Meningitis is an inflammation of the meninges – the protective membranes surrounding the brain and spinal cord. It can be caused by bacteria, viruses, fungi, or other pathogens, and its severity varies greatly depending on the cause. Bacterial meningitis is a medical emergency that requires immediate treatment, while viral meningitis is usually less severe.
Classic Symptoms of Meningitis
Symptoms can develop and worsen rapidly within hours. The hallmark symptoms of meningitis include:
- Severe headache: Sudden onset, intense, and persistent.
- High fever: Often above 38.5 °C (101.3 °F), frequently accompanied by chills.
- Neck stiffness (meningismus): Difficulty bending the neck forward due to pain and resistance.
- Sensitivity to light (photophobia): Light feels uncomfortable or painful.
- Sensitivity to sound (phonophobia): Sounds are perceived as disturbing or painful.
- Nausea and vomiting: Often accompanying the headache.
- Altered consciousness: Confusion, drowsiness, or loss of consciousness are serious warning signs.
Additional Symptoms by Cause
Bacterial Meningitis
Bacterial meningitis can additionally present with:
- Petechiae or purpura: Small, non-blanching red or purple spots on the skin – a potential sign of life-threatening septicaemia.
- Rapid deterioration of general health within hours.
- Seizures.
Viral Meningitis
Viral meningitis typically runs a milder course. Headache, fever, and neck stiffness may be present but are usually less severe. Most patients recover within one to two weeks, often without specific treatment.
Symptoms in Infants and Young Children
In infants and young children, classic symptoms may not be obvious. Parents should watch for:
- Bulging fontanelle (the soft spot on the head)
- Persistent, unusual crying or irritability
- Fever or abnormally low body temperature
- Poor feeding and loss of appetite
- Pale or mottled skin
- Body stiffness or floppiness
When to Seek Emergency Care?
Meningitis is a medical emergency. If the above symptoms occur – especially neck stiffness, high fever, severe headache, and skin rash – call emergency services (911 or 112) immediately or go to the nearest emergency room. Every hour of delay can have life-threatening consequences.
Diagnosis
Meningitis is diagnosed in a clinical setting through:
- Physical examination: Checking for meningeal signs such as the Kernig and Brudzinski signs.
- Lumbar puncture (spinal tap): Collection of cerebrospinal fluid (CSF) to identify pathogens and inflammatory markers.
- Blood tests: Measuring inflammatory markers such as CRP, white blood cell count, and procalcitonin.
- Imaging: CT or MRI of the head to rule out other causes.
Treatment
Treatment depends on the underlying cause:
- Bacterial meningitis: Immediate administration of antibiotics (e.g., cephalosporins) and corticosteroids to reduce inflammation. Intensive inpatient care is often required.
- Viral meningitis: Mainly symptomatic treatment with pain relievers, bed rest, and adequate fluid intake. Antiviral medications are used for specific viruses such as herpes.
- Fungal meningitis: Treatment with antifungal agents such as amphotericin B.
Prevention
Vaccination provides effective protection against certain meningitis-causing pathogens. Recommended vaccines include:
- Meningococcal vaccines (types A, C, W, Y and B)
- Pneumococcal vaccine
- Haemophilus influenzae type b (Hib) vaccine
These vaccines are routinely recommended in childhood and can also protect adults in certain risk groups.
