It is true thought that in some cases, the bacteria go beyond colonisation, and cross into the bloodstream to cause serious disease. The bacteria can cause two distinct forms of the disease - meningitis and septicaemia (blood poisoning).
A major problem with bacterial meningitis is that the symptoms are often mistaken for the common flu and as a lot of outbreaks tend to be in the winter months, this mistake is compounded but the fact that there is also a lot of flu around in the winter months. Tragically this can sometimes mean that by the time the patient is diagnosed it can be too late to save them. Usually the first symptoms of meningitis and septicaemia are classic flu-like symptoms with a high temperature, and headache, often accompanied by nausea and vomiting, or aching joints. Other signs of meningitis can include stiffness in the neck and an intolerance of bright light, whilst the clearest symptom of septicaemia is a pinprick rash which can be identified by the simple tumbler test, where you press tumbler on the rash and if it does not blanch or disappear it could mean the person has meningitis.
However, many patients show these more specific symptoms too late or not at all, which makes the disease very difficult to diagnose. This, in addition to the incredible speed by which the disease strikes, is why many believe that the only way to truly eradicate the disease is through prevention.
