Meningitis occupies a particular place in the minds of Australian parents. The condition is rare enough that most families will never encounter it, but serious enough that missing the signs carries consequences no one should have to face. The illness moves on its own timeline, and the symptoms it produces in its early hours often resemble infections that pass within days without any treatment at all.
What Can Cause Meningitis?
Several different types of meningitis exist, and the cause determines how serious the illness becomes.
Bacterial Meningitis
The bacteria that cause bacterial meningitis live harmlessly in the noses and throats of healthy people and are spread through close contact. Up to half of young children carry pneumococcal bacteria at any given time without becoming sick.
Viral Meningitis
Viral meningitis is more common than bacterial meningitis and usually less severe. Viral meningitis cases spread through contact with infections such as mumps, herpes simplex, influenza, and West Nile virus.
Fungal Meningitis
Fungal meningitis is uncommon and affects people with weakened immune systems. Cryptococcal meningitis occurs when people inhale fungal spores from soil contaminated with bird droppings.
Parasitic Meningitis
Parasitic meningitis, also called eosinophilic meningitis, results from parasites such as rat lungworm.
Non-Infectious Causes
Sometimes meningitis develops without an infection. Drug-induced aseptic meningitis can result from certain medications, including some antibiotics and anti-inflammatory drugs. Cancer, autoimmune conditions, and head injuries may also lead to meningitis.
Signs and Symptoms of Meningitis
The signs and symptoms of meningitis can appear within hours or develop over several days. Meningitis symptoms in older children and adults differ from those in babies and toddlers, so parents and carers must recognise the warning signs for each age group.
Common Symptoms in Adults and Older Children
- High fever that comes on suddenly
- Severe headache that pain relief does not ease
- A stiff neck
- Sensitivity to bright lights
- Nausea and vomiting
- Confusion or difficulty concentrating
- Drowsiness or reduced consciousness
- Seizures or fits
Symptoms in Babies and Young Children
Meningitis in children under two years old can be harder to recognise because many of the symptoms overlap with common childhood illnesses. The difference is in the pattern and intensity. Parents should watch for:
- High-pitched, moaning, or whimpering cry
- Unusual irritability and dislike of being handled
- Refusing feeds
- Vomiting
- Extreme sleepiness or difficulty waking
- Floppy and unresponsive behaviour
- Bulging or tense fontanelle (the soft spot on a baby’s head)
- Arching of the back
- Rapid or unusual breathing patterns
- A temperature that is unusually high or unusually low
Very young babies may not develop a fever even when seriously ill with meningitis. A child has meningitis as a possibility any time these symptoms appear together, regardless of whether a rash is present.
First Aid for Meningitis
Meningitis is a severe condition that cannot be treated at home, and antibiotic treatment must begin as soon as possible when bacterial meningitis is suspected.
Trust your instincts. Call Triple Zero (000) immediately or take the person to the nearest emergency department if someone appears very unwell with symptoms that could indicate meningitis. While waiting for help:
- Keep the person comfortable in a dark, quiet room if they are sensitive to light
- Monitor their breathing and consciousness
- Do not give them anything to eat or drink in case they need surgery
- Note the time when symptoms started and how they have progressed
Prevention remains the most powerful weapon against bacterial meningitis. Vaccination programs have reduced cases of meningitis from several bacterial causes, and good hygiene practices help limit the spread of both bacterial and viral meningitis.
Meningitis Prevention
Vaccination is the single most effective way to protect your child from bacterial meningitis. If your child’s vaccinations are up to date, they already have strong protection against the most common causes. Travellers to areas where meningitis is more common should discuss vaccination with their doctor before departure.
The bacteria and viruses that cause meningitis spread through close contact, so these habits help reduce the risk of meningitis among families and communities:
- Wash hands often with soap and water, especially before eating and after using the toilet
- Cover coughs and sneezes with a tissue or your elbow
- Avoid sharing drinks, food, utensils, lip balm, or toothbrushes
- Stay home when you are unwell to avoid spreading infections to others
- Keep common surfaces clean, especially in childcare settings
If someone close to you or your child is diagnosed with meningococcal meningitis or Hib meningitis, your doctor can advise whether preventive antibiotics are needed.
Be Ready to Act When It Matters
Meningitis can be a life-threatening condition and your ability to recognise the warning signs and act could save someone you love. While vaccines have reduced many cases of bacterial meningitis, this disease still claims lives and leaves survivors with permanent disabilities. First aid training gives you the knowledge and practical skills to respond when someone’s life hangs in the balance.
FAQs
How Long Does It Take to Recover From Meningitis?
Recovery depends on the type and severity of meningitis. Mild cases may resolve within a couple of weeks, while more serious infections can take months.
Can Someone Get Meningitis More Than Once?
A person can develop meningitis multiple times, particularly if they have an underlying condition that weakens their immune system. Having one type of meningitis does not provide protection against other types, so vaccination against multiple causes remains important.
What Long-Term Effects Can Meningitis Cause?
Meningitis causes lasting complications in up to one in five survivors. Hearing loss is the most common after-effect, ranging from mild impairment to complete deafness. Other complications include learning difficulties, memory problems, epilepsy, vision loss, and problems with balance and coordination.
