title: Viral meningitis, active and reserve components, U.S. Armed Forces,  2002-2011.
abstract: Viruses are the most common causes of meningitis, a condition characterized by inflammation of the protective membranes that surround the brain and spinal cord. During the 10-year surveillance period, there were 3,205 confirmed cases, 724 probable cases, and 2,495 suspected cases of viral meningitis among active and reserve component members. In all three categories of cases, the most common diagnoses were meningitis due to  enteroviruses; however a majority of these were unspecified enteroviruses.  Nearly two-thirds (64.2%) of all cases due to enteroviral infection were hospitalized; on average, cases were hospitalized for 3.2 days. Numbers of cases peaked in late summer/early fall; and higher than average numbers of cases in 2003 reflected several outbreaks that occurred in civilian populations that year. Six states (Texas, California, Virginia, North Carolina, Florida, Georgia) reported the most cases in 2003 and overall during the period. Prevention of viral meningitis relies upon the interruption of viral transmission, e.g., thorough hand washing and disinfection of contaminated surfaces.
