The 18 year old British girl who was taken to the hospital unconscious after inhaling laughing gas was airlifted to Britain from Heraklion on Monday for further treatment without recovering consciousness.
Heraklion university Hospital issued a statement saying that the condition of the girl who suffered brain damage was due to a bacterial meningitis infection and septicemia.
Meningococcal bacteria can cause meningitis, septicaemia or both. Most people who get the disease have some symptoms of both meningococcal meningitis and meningococcal septicaemia.
Septicaemia is the more life threatening form of the disease and is more dangerous when there are no signs of meningitis.
