A39.0: Meningococcal meningitis

You have been infected with meningococci.

You have been infected by certain bacteria called meningococci. These bacteria are typically transmitted person-to-person, for example by sneezing or shaking hands. The bacteria have caused inflammation in your cerebral membranes.

On the outside of the brain and spinal cord there are three thin meninges (linings). A tough meninx, the dura mater, is on the outside. Below that are two soft meninges. Meningitis involves inflammation in one or more of these cerebral membranes. It is then possible to get a high fever and feel very sick. You can get severe headaches and your neck might be stiff or painful. You may find it difficult to tolerate bright light and loud noise. Sometimes you may also feel nauseated and feel like you have to vomit. Seizures are also possible or you may lose consciousness. A skin rash is common too with a meningeal inflammation.
