Meningitis may be defined as an inflammatory
response to infection (bacterial, viral) of the pia-arachnoid and the
cerebrospinal fluid (CSF) of the sub arachnoid space. It is characterized by
sudden onset of febrile illness with signs and symptoms of meningeal
involvement. The incidence rate of bacterial meningitis is between 3 and 5 per100,000 people per year in USA. The disease is even more common in developing

22/100000 according to the national surveillance data. Read more>>>>>>>>>>>>
