A bacterial or viral infection of the fluid surrounding the brain and spinal cord usually causes the swelling. However, injuries, cancer, certain drugs, and other types of infections also can cause meningitis.
There are a few different types of meningitis, including viral, bacterial, and fungal meningitis.
There are actually five types of meningitis — bacterial, viral, parasitic, fungal, and non-infectious — each classified by the cause of the disease.
What is bacterial meningitis? Meningitis is an infection of the membranes (meninges) that protect the spinal cord and brain. When the membranes become infected, they swell and press on the spinal cord or brain. This can cause life-threatening problems.
