Meningitis is an infection of the protective membranes that surround the brain and spinal cord.
It can affect anyone but is most common in babies, young children, teenagers and young adults. It can be very serious if not treated quickly.
The cause of the infection - either certain bacteria or viruses - can be determined by tests.
Bacterial meningitis is rarer but more serious than viral meningitis. It can lead to blood poisoning or sepsis, and can affect the brain.
