Meningitis is most commonly caused by viral or bacterial infection. Signs and symptoms of viral and bacterial meningitis are almost similar and can therefore, be difficult to differentiate. Bacterial meningitis is considered as a medical emergency because it can progress rapidly and lead to septicaemia (blood poisoning) or even death. Meningitis can affect a person of any age group, but the incidence is more common in young children (<4 years) and children in the late teenage years. In the initial stages of illness, the signs and symptoms of meningitis may be mistaken for flu (influenza), however, in meningitis, the signs and symptoms tend to progress more rapidly over several hours or over one or two days and are therefore, more severe.
