Meningitis is an infection that causes inflammation of the membranes (meninges) caused by a bacterial, viral , fungal or protozoal infection . The brain and spinal cord are covered by connective tissue layers collectively called the meninges which form the blood-brain barrier . The primary functions of the meninges and of the cerebrospinal fluid (produced in and circulating in the meninges) is to protect, cushion, nourish, and support the brain and spinal cord . Bacterial and viral are the two most common forms of meningitis . But bacterial meningitis is usually severe and can even be deadly . Death can occur in as little as a few hours. Most people recover from meningitis. However, permanent disabilities (such as brain damage, hearing loss ) can result from the infection
