Meningitis is a condition in which the meninges are inflamed. The most often symptoms include: high fever, headache, intolerance to light and sometimes to loud noises, and pain when in specific postures. There are also several signs that are usually easily recognizable by a doctor.
Lumbar puncture is the definitive test for meningitis. However, it should not be performed, if the other signs and the blood laboratory tests do not indicate meningitis.
The symptoms might be related to a virus that caused similar signs as in meningitis. However, it can not be told whether the virus will spread to the meninges and start real meningitis.
