Meningococcal Disease is caused by 13 groups of the bacteria. Here in the UK, it is almost exclusively caused by MenB, MenC, MenW or MenY. This bacteria lives in the back of the nose and throat and shows no symptoms or illness in 10 of 100 carriers, making it very easy to spread the disease.
It is spread by close contact with another person who carries the bacteria.
Meningococcal bacteria can cause serious illnesses like meningitis or septicemia which can cause sepsis and death.
Whilst Meningococcal infections can occur at any age, babies, young children and teenagers are particularly vulnerable.
