Aseptic meningitis epidemiology and demographics


 * Associate Editor-In-Chief:

Overview
Aseptic meningitis is relatively common, with an incidence of around 10/100,000. The male:female ratio is around 1:1.

There are approximately 8,300 – 12,700 cases of AM / year in the U.S., however this is likely a gross underestimate due to underreporting.


 * There is a marked seasonal variability, similar to that of enterovirus, which is the most commonly diagnosed cause of AM.
