Diagnosis

Table of Contents

Meningitis is diagnosed by testing some of the fluid that surrounds the spinal cord for disease-causing bacteria or infection-fighting cells. The fluid is removed from the spinal cord with a needle in a procedure known as a spinal tap or lumbar puncture.

Expected Duration

Viral meningitis tends to get better on its own in seven to 10 days. In contrast, if bacterial meningitis is not diagnosed and treated early, it can cause permanent disability or death. The length of time that medication is needed for bacterial meningitis depends on the person's age, response to the medication and other factors.
