Encephalitis may result from acute viral invasion of the brain and a concomitant inflammatory response or from a postinfectious, autoimmune process characterized by demyelination following a viral illness or vaccination (acute disseminated encephalomyelitis). The majority of the approximately 8,000 to 13,000 cases of aseptic meningitis and approximately 20,000 cases of encephalitis reported annually in the United States are caused by viral infections. Common causes of viral meningitis include: enterovirus (85%-95% of all cases in which a pathogen is identified), mumps virus (occurs in 10%-30% of mumps cases), and herpesvirus (0.5%-3% of all cases of aseptic meningitis).and herpesvirus (0....
