The mortality for viral meningitis without encephalitis is less than 1%. In patients with deficient humoral immunity (eg, agammaglobulinemia), enteroviral meningitis may have a fatal outcome. Patients with viral meningitis usually have a good prognosis for recovery. The prognosis is worse for patients at the extremes of age (ie, < 2 or >60 years) and those with significant comorbidities and underlying immunodeficiency.
