Signs and Symptoms of Meningitis
Meninges are membranes that cover or envelope the brain and the spinal cord. There are three meninges—dura mater, arachnoid, and pia mater. The meninges protect the central nervous system. When bacteria affect these membranes, the condition is then called meningitis. Meningitis is of three types—bacterial, fungal, and viral. Bacterial meningitis is life-threatening and can also spread among people when they come in close contact with each other. Viral meningitis, however, is not as dangerous as bacterial meningitis and can be recovered without treatment.
