Meningitis and those at risk
Meningitis is the inflammation of the 3 layers of membranes known as meninges that protect
the brain and spinal cord.
1. The delicate inner layer is the pia mater.
2. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain.
3. The tough outer layer is called the dura mater.
Anyone can be affected by meningitis, but certain factors may increase risk.
