Meningococcal disease is a severe illness caused by bacteria (germs) called Neisseria meningitidis (sometimes also called meningococci).
- These germs can be found in the nose and throat of up to 10% of the population, where they are almost always harmless. They are called 'carriers'.
- In a very small number of people, for reasons that are not clear, the germs spread into the blood stream and cause very serious illnesses.
Meningococcal disease can affect all age groups, but is most common in young children under 5 years old, and young people 15 to 24 years old.
In South Australia in 2011 there were 21 people who became ill from meningococcal infections.
- If a person has any of the signs of meningococcal infection, such as rapidly becoming very ill and having a rash of reddish purple spots or bruises, medical treatment is needed urgently.
- A person may have meningococcal B disease even if he or she has been immunised against meningococcal C disease.
It is recommended that all Australian children are given meningococcal C vaccine when they are aged 12 months.
