Meningitis is an infection affecting the protective membranes around the brain and spinal cord, which are called the meninges. It can be caused by bacteria or a virus.
While meningitis can affect anyone, it is most common in babies, young children and teenagers. Failing to quickly identify and treat meningitis can cause serious, and permanent, health complications.
This includes:
- Life-threatening blood poisoning
- Permanent damage to the brain or nerves
- Hearing loss
- Paralysis
- Learning difficulties
- Behavioural and emotional difficulties
It can also be fatal in some cases.
