what what is meningitis

Meningitis is an inflammation of the protective membranes, known as the meninges, that surround your brain and spinal cord.¹

Main Causes

• Viral Meningitis: This is the most common and generally less severe form. It often improves on its own without specific medical treatment.¹
• Bacterial Meningitis: This is rare but much more dangerous and potentially life-threatening. It can cause rapid blood poisoning (septicaemia/sepsis) and permanent brain or nerve damage if not treated immediately with hospital care and antibiotics.¹
• Other Causes: Less commonly, meningitis can be caused by fungi, parasites, or non-infectious factors like certain medications or injuries.¹

Key Symptoms

Symptoms can appear very quickly—sometimes within a matter of hours:¹²

• High fever
• Severe headache
• Stiff neck
• Sensitivity to light (photophobia)
• Vomiting or nausea
• Confusion, drowsiness, or seizures
• A non-blanching skin rash (a rash that doesn't fade when you press a clear glass tumbler against it)¹²³⁴⁵

(For detailed guidance on symptoms and local health services, visit the NHS inform Meningitis guideNHS inform Meningitis guide). If you'd like, let me know:

• Who is experiencing symptoms (an infant, teenager, or adult)?
• Are you looking for information on routine vaccinations?

Meningitis is an infection and inflammation of the meninges —the protective membranes that surround your brain and spinal cord. It can be very serious and requires quick medical attention.¹

Main Types & Causes

• Bacterial Meningitis: The most dangerous form. It is a medical emergency that can become life-threatening very quickly if not treated with hospital antibiotics.¹
• Viral Meningitis: More common and generally less severe. Most people recover on their own at home within 7 to 10 days with rest and painkillers.¹
• Other Causes: Less commonly, meningitis can be triggered by fungal infections, parasites, or non-infectious conditions like reactions to certain medications.

Key Symptoms to Watch For

Symptoms often develop suddenly and can easily be mistaken at first for flu, a stomach bug, or a hangover. They include:¹

• Severe headache that gets worse
• Stiff neck
• High temperature (fever) or very cold hands and feet
• Sensitivity to bright light (photophobia)
• Vomiting and confusion
• A distinct rash or spots that do not fade when you press the side of a clear glass against them (Note: this rash can be harder to spot on brown or black skin.) ¹

Signs in Babies and Young Children:

• A high-pitched, unusual cry
• Poor feeding or reluctance to feed
• Being overly floppy, unresponsive, or unusually stiff
• A bulging soft spot on the top of their head¹

What to Do

If you or someone else displays symptoms of meningitis, seek urgent medical help immediately. You can read more about emergency guidance and vaccination schedules (such as MenB and MenACWY) directly on the NHS Meningitis Guide.¹

Are you asking out of general curiosity, or are you or someone you know currently experiencing symptoms? If someone is unwell right now, please call emergency services (like 999 or 111) immediately.

Meningitis is a serious illness where the protective membranes surrounding your brain and spinal cord (called the meninges) become inflamed or swollen.

It can affect anyone, including babies, children and adults. Some types can become life-threatening very quickly.

What causes meningitis?

There are several types:

1. Bacterial meningitis – caused by bacteria. This is the most dangerous type and is a medical emergency.
2. Viral meningitis – caused by viruses. It is more common and usually less severe.
3. Fungal meningitis – rare, usually affecting people with weakened immune systems.

What are the symptoms?

Common symptoms include:

• Severe headache.
• High temperature (fever).
• Stiff or painful neck.
• Feeling sick or vomiting.
• Sensitivity to bright lights.
• Confusion or difficulty staying awake.
• Seizures.
• Sometimes a rash that doesn't fade when pressed against a glass.

Important: Not everyone gets all these symptoms, and a rash may not appear.

Is meningitis dangerous?

Yes, particularly bacterial meningitis. It can cause:

• Brain damage.
• Hearing loss.
• Seizures.
• Blood poisoning (sepsis).
• Death if treatment is delayed.

Can you catch meningitis?

Some forms can spread between people through close contact, coughing, kissing or sharing saliva, depending on the germ causing it.

Vaccines are available to protect against several important types of meningitis.

When to get urgent help

If you or someone else has a severe headache with fever, a stiff neck, confusion, unusual sleepiness or a rash that doesn't fade under pressure, seek emergency medical help immediately. In the UK, call 999. Don't wait for a rash to appear.

Can I ask you something? Are you asking because you've heard about meningitis, or are you worried that you or someone you know might have it?
