Meningitis occurs when the lining around your brain and spinal cord (meninges) becomes inflamed.
It can be fatal if not treated quickly, and can result in life-threatening issues such as blood poisoning (septicaemia) and permanent damage to the brain or nerves. The illness can be spread through sneezing, coughing and kissing - and is usually passed on by people carrying the virus in their nose or throat but aren't ill themselves.
While meningitis can affect people of all ages - it is most common in babies, young children, teens, and young adults. Most people associated the illness with a rash that does not fade when a glass is rolled across it. However, this symptom does not always present itself. In fact, many of the early warning signs of the condition could easily be mistaken for a common cold.
