Epidemiology of bacterial meningitis in Lombardy Region in the period 2000-2006.

Epidemiological study of bacterial meningitis, particularly those forms susceptible to vaccination, is an indispensable tool in choosing vaccination strategies. Lombardy Region, where approximately 20% of the Italian population resides, has conducted an in-depth study on invasive meningococcal diseases and pneumococcal meningitis using available health statistics and performing a control of single cases to achieve complete knowledge of the phenomenon. The results, relating to the period 2000-2006, indicate limited incidence rates both for the general population and childhood age groups that do not justify hypotheses of a universal offering of the specific vaccines.
