Overview
Meningitis is an infection that causes swelling (inflammation) of the protective layers around your brain and spinal cord, called the meninges. It can be caused by germs like bacteria, viruses, or fungi. Bacterial meningitis is serious and needs urgent medical care, while viral meningitis is more common and usually less severe.
Key facts
- Meningitis can affect anyone, but is most dangerous for babies, young children, teenagers, and older adults.
- Bacterial meningitis is a medical emergency and requires hospital treatment right away.
- Vaccines are available to protect against some of the most common causes of meningitis.
Meningitis is rare but serious. In the UK, there are about 3,200 cases of bacterial meningitis each year. Viral meningitis is more common but often milder.
Meningitis can affect people of all ages, but babies under 1 year, children under 5, teenagers and young adults, older adults, and people with weakened immune systems are at higher risk.
Symptoms
- A rash that does not fade when you press a glass against it (glass test)
- Severe headache with a stiff neck and fever
- Confusion or loss of consciousness
- Seizures or fits
- Breathing very fast or feeling like you can't breathe
- Cold hands and feet with a rash
- ⚠Fever with a very bad headache that gets worse
- ⚠Vomiting (especially if it won't stop)
- ⚠Sensitivity to light (photophobia)
- ⚠Drowsiness or difficulty waking up
- ⚠Muscle or joint pain
Common symptoms
- High fever
- Severe headache that feels different from usual headaches
- Stiff neck – trouble touching your chin to your chest
- Sensitivity to light (photophobia)
- Nausea or vomiting
- Confusion or difficulty concentrating
Symptoms in children
- Irritability and fussiness – crying more than usual
- Poor feeding or refusing to eat
- Being very sleepy or hard to wake up
- A bulging soft spot on the top of the head (fontanelle) in babies
- High-pitched or moaning cry
- Stiff body or floppy limbs
Symptoms in older adults
- Confusion or disorientation that comes on quickly
- Lethargy – feeling very tired and slowed down
- Fever may be mild or even absent
- Stiff neck (may be less obvious)
- Loss of appetite
Causes
Main causes
- Bacterial infections – the most common are meningococcus, pneumococcus, Hib (Haemophilus influenzae type b), group B streptococcus, and listeria
- Viral infections – usually enteroviruses, but also herpes simplex virus, mumps, and others
- Fungal infections – rare, mainly in people with very weak immune systems
Risk factors
- Age – being a baby, young child, teen, or older adult
- Living in close quarters, like dormitories, military barracks, or day care centers
- Not having had recommended vaccinations
- Having a weakened immune system (from conditions like HIV or certain medications)
- Head injury or brain surgery
When to see a doctor
See a doctor urgently if:
- If you or your child have any symptoms of meningitis, especially fever with severe headache, stiff neck, and sensitivity to light
- If a rash appears that does not fade when pressed with a glass
- If you see any of the emergency symptoms listed above
Book a routine appointment if:
- If you have been in close contact with someone diagnosed with meningitis, even if you feel fine – you may need preventive antibiotics or monitoring
- If you have mild symptoms like headache and fever after a trip to an area where meningitis is more common
Diagnosis
Doctors suspect meningitis based on your symptoms and a physical exam. They will check your neck flexibility, look for a rash, and test your reflexes. If meningitis is possible, they will start treatment immediately while running tests to confirm the cause.
Tests that may be done
- Lumbar puncture (spinal tap) – a needle takes a sample of fluid from around your spine to look for infection
- Blood tests – to check for bacteria or viruses and measure signs of inflammation
- Imaging – a CT or MRI scan to look at the brain and rule out other problems
- PCR test – a rapid test on spinal fluid or blood to identify the specific germ
What to expect at your appointment
You or your child will be admitted to hospital. The tests are done quickly, often within hours. A lumbar puncture can sound scary but is done with local anaesthetic and usually takes less than 30 minutes. Treatment will start before all results come back, because time is critical.
Treatment
Treatment depends on what is causing the meningitis. Bacterial meningitis must be treated in hospital with antibiotics given through a vein. Viral meningitis usually gets better on its own with rest and hydration, though some viral types need antiviral medicine. Fungal meningitis requires long courses of antifungal medications.
Self-care at home
- Get plenty of rest – your body needs energy to fight the infection
- Drink fluids to stay hydrated, but follow your doctor's instructions if vomiting
- Take over-the-counter pain relievers for headache and fever (check with your doctor first)
Medical treatments
For bacterial meningitis, treatment includes intravenous antibiotics and often corticosteroids to reduce swelling. Supportive care may include oxygen, fluids, and medicines to control seizures or low blood pressure. In severe cases, intensive care (ICU) is needed. For viral meningitis, most people recover with rest, fluids, and pain relief – antiviral medication may be given for certain viruses like herpes. Fungal meningitis is treated with antifungal drugs given intravenously or orally for many months.
When is surgery considered?
Surgery is rarely needed. It may be used to drain an abscess (a pocket of pus) in the brain, to remove damaged tissue, or to relieve pressure inside the skull in very severe cases.
Living with this condition
Recovery from meningitis can take weeks to months. Fatigue is very common, so plan for plenty of rest. You may need to take time off work or school. Follow-up appointments with your doctor are important to check for any long-term effects.
Lifestyle tips
- Return to normal activities slowly – listen to your body and don't push too hard
- Get plenty of sleep at night and take short naps during the day if needed
- Avoid alcohol and smoking, as these can slow recovery
Diet and exercise
Eat a balanced diet with fruits, vegetables, protein, and whole grains to support your immune system. Drink water regularly. Gentle exercise, like short walks, can help with energy levels, but avoid strenuous activity until your doctor says it's safe.
Mental health and emotional wellbeing
Meningitis can be a frightening experience. Many people feel anxious, depressed, or have trouble sleeping after recovery. Some may have nightmares or flashbacks (post-traumatic stress). It is normal to need time to process what happened. Talking to a counsellor or joining a support group can help.
Prevention
Many cases of meningitis can be prevented with vaccines and good hygiene. Vaccines are the most effective way to protect against bacterial meningitis. Practising good hand washing, not sharing utensils or drinks, and staying away from sick people also help reduce the risk.
Vaccines
Vaccines protect against several common causes of meningitis, including meningococcal (MenACWY, MenB), pneumococcal, Hib, and MMR (for mumps and measles). These are part of routine childhood immunisation in many countries. Some may be recommended for travel to areas where meningitis is more common.
Screening programmes
There is no routine screening test for meningitis in healthy people. However, if you have been in close contact with someone with meningitis, public health authorities may offer antibiotics or monitoring to prevent infection.
Complications
If left untreated
- Sepsis (blood poisoning) – a life-threatening response to infection that can cause organ failure
- Brain damage – including problems with memory, concentration, or learning
- Hearing loss – partial or total, which may be permanent
- Seizures that continue long-term (epilepsy)
- Limb loss – sometimes fingers, toes, or limbs must be amputated because of sepsis
Long-term outlook
With early diagnosis and treatment, most people recover from meningitis. However, it can be a very serious illness, and many survivors have long-term effects such as fatigue, headaches, hearing loss, or emotional challenges. Vaccination is the best way to reduce the risk. If you or your child had meningitis, support and rehabilitation can help you live well.
