Cases of bacterial meningitis caused by Haemophilus influenzae, Neisseria meningitidis, group A Streptococcus, and Listeria monocytogenes should be reported to CDC's National Notifiable Diseases Surveillance System under the disease codes specific for these organisms. Only cases of bacterial meningitis caused by organisms other than those specified should be reported as cases of "meningitis, other bacterial."
