Meningitis: Recognising the Symptoms and When to Seek Care

What Is Meningitis?

Meningitis is a medical condition characterised by inflammation of the meninges, the protective membranes that surround the brain and spinal cord. These membranes play an important role in protecting the central nervous system.

Meningitis is a serious and potentially life-threatening illness that requires prompt medical attention. It occurs more frequently in babies, children, teenagers, and young adults, although people of any age can be affected. 

Recognising Meningitis Symptoms

Common symptoms of meningitis include:

• Fever

• Headache

• Nausea and vomiting

• Neck stiffness

• Sensitivity to light (photophobia)

• Confusion

• Drowsiness

• Joint pain

• Seizures

• Skin rashes (petechiae)

Meningitis Symptoms in Babies

Meningitis symptoms in babies may differ from those in adults and can be harder to recognise. Warning signs in infants include:

• A bulging soft spot (fontanelle) on the head

• Poor feeding

• Excessive sleepiness or difficulty waking

• Lethargy

• High-pitched crying

What Causes Meningitis?

Meningitis is classified based on its underlying cause.

1. Viral meningitis

Viral meningitis is the most common form and is generally less severe than bacterial meningitis. It is caused by viruses associated with common infections such as chickenpox, influenza, mumps, and measles. Viral meningitis is usually milder than bacterial meningitis but still requires medical evaluation to rule out more serious causes.

2. Bacterial meningitis

Bacterial meningitis is a medical emergency that requires immediate treatment. It is caused by various types of bacteria, with symptoms typically developing within 3 to 7 days after exposure.

An exception is tuberculosis (TB) meningitis, which may present much later. Some bacteria responsible for meningitis can also cause sepsis, a life-threatening condition triggered by an overwhelming immune response to infection that may lead to organ failure and death if not treated promptly.

3. Fungal meningitis

Fungal meningitis is rare and usually occurs when fungal spores are inhaled and spread to the central nervous system. It is more common in individuals with weakened immune systems.

4. Parasitic meningitis

Parasitic meningitis is uncommon and results from parasites that typically infect animals. Humans may develop the condition after consuming contaminated food or water.

Is Meningitis Contagious?

Meningitis itself is not contagious. However, the viruses or bacteria that cause meningitis can spread from person to person, particularly in close-contact settings.

Who Is at Higher Risk of Meningitis?

Individuals at higher risk of meningitis include:

• Babies and young children

• Teenagers and young adults

• Older adults

• People with weakened immune systems such as those with HIV, cancer, or on immunosuppressive medication

• Individuals with incomplete vaccination histories

• People with alcohol misuse

  
  

How Is Meningitis Diagnosed?

Diagnosis for meningitis is based on a combination of medical history, physical examination, and diagnostic testing. Doctors assess symptoms, recent illnesses, and possible exposure to infection. 

Physical examination focuses on neurological signs such as neck stiffness, altered mental state, and light sensitivity.

Diagnostic tests may include lumbar puncture (spinal tap) to analyse cerebrospinal fluid, blood tests, and imaging studies such as CT scans or MRI.

Treatment for Meningitis

Treatment for meningitis depends on the cause and may include:

• Antibiotics for bacterial meningitis

• Antiviral medications for certain viral infections

• Antifungal therapy for fungal meningitis

• Steroids to reduce brain inflammation

• Pain relief medications

• Intravenous fluids to maintain hydration

Viral meningitis often resolves within 7 to 10 days. Recovery from bacterial or fungal meningitis may take longer, and full recovery can require weeks or months. Some individuals may experience long-term complications.

Possible Complications of Meningitis

Complications of meningitis may include:

• Partial or complete hearing loss

• Vision impairment

• Memory and concentration difficulties

• Recurrent seizures

• Problems with coordination, balance, or movement

• Learning and behavioural difficulties in children

• Arthritis

• Limb loss in severe cases

How Can Meningitis Be Prevented?

The risk of meningitis can be reduced through:

• Adhering to recommended vaccination schedules

• Vaccination for high-risk individuals

• Preventive antibiotics for those exposed to certain bacterial infections

• Practising good hygiene

• Safe food handling

• Avoiding close contact with unwell individuals

• Avoiding contaminated water

• Ensuring meat and seafood are thoroughly cooked
