What Is Meningitis?
Meningitis is a relatively rare infection that affects the delicate membranes — called meninges (men-in’-jeez) — that cover the brain and spinal cord. Bacterial meningitis can be deadly and contagious among people in close contact.
Viral meningitis tends to be less severe and most people recover completely without specific therapy.
Fungal meningitis is a rare form of meningitis and generally occurs only in people with weakened immune systems.
What Causes Meningitis?
Meningitis is almost always caused by a bacterial or viral infection that began elsewhere in the body, such as in the ears, sinuses, or upper respiratory tract. Less common causes of meningitis include fungal infection, autoimmune disorders, and medications.
