More than 10,000 cases of viral meningitis are reported annually, but the actual incidence may be as high as 75,000. Lack of reporting is due to the uneventful clinical outcome of most cases and the inability of some viral agents to grow in culture.

According to reports from the Centers for Disease Control and Prevention (CDC), inpatient hospitalizations resulting from viral meningitis range from 25,000-50,000 each year. An incidence of 11 per 100,000 population per year has been estimated in some reports.
