What is meningitis?

Meningitis is a rare but serious infection of your meninges (the membranes covering your brain and spinal cord).

Meningitis is usually caused by a virus or bacteria, and sometimes it’s caused by a fungus.

Viral meningitis is usually a less dangerous form of meningitis and most commonly affects children. Bacterial meningitis is a medical emergency. Early diagnosis and treatment are vital.

It is often not possible to tell the difference between viral and bacterial meningitis from the symptoms alone.

How is meningitis treated?

People with meningitis are usually be admitted to hospital. Treatment will depend on the type of infection that has caused the meningitis.

Viral meningitis

There is no specific treatment for viral meningitis and people usually get better with plenty of rest and fluids.

Pain relief medicines, such as paracetamol, can be used to ease headache and fever.

Viral meningitis is not treated with antibiotics because antibiotics are not effective against viral illnesses.

Bacterial meningitis

Bacterial meningitis is a medical emergency that needs immediate treatment.

You will get antibiotics to treat the infection.

Other medicines, such as corticosteroids, may also be given to help reduce your risk of complications.

Fungal meningitis

Meningitis that’s caused by a fungus is treated with anti-fungal medicines.

Can meningitis be prevented?

If you’ve been in close contact with someone who has meningococcal disease, you may be given antibiotics to reduce your risk of infection.

• Wash your hands regularly.
• Don’t share drink bottles, cups or cutlery.
• Sneeze into your elbow.
• Throw tissues into the bin straight after use and wash your hands.
