Are bacterial meningitis and hepatitis A reportable diseases?

Yes, both bacterial meningitis and hepatitis A are reportable diseases to public health authorities.

Both bacterial meningitis and hepatitis A must be reported to the CDC's National Notifiable Diseases Surveillance System, as they are nationally notifiable diseases that require public health tracking for outbreak detection and prevention. 1

Bacterial Meningitis Reporting Requirements

Bacterial meningitis is reportable with specific requirements based on the causative organism 1:

• Specific organism reporting: Cases caused by Haemophilus influenzae, Neisseria meningitidis, group A Streptococcus, and Listeria monocytogenes must be reported under disease codes specific to these organisms
• "Bacterial meningitis, other": Only cases caused by organisms other than those listed above should be reported under this general category
• Case definition: A confirmed case requires either laboratory confirmation (isolation of bacteria from CSF) or a clinically compatible case with positive blood culture

Reporting Timeliness

The median time for bacterial meningitis reporting to national surveillance is approximately 20 days 2, though this varies by state. Given that bacterial meningitis can progress rapidly to shock and death 1, prompt local reporting is critical even though national reporting may take longer.

Hepatitis A Reporting Requirements

Hepatitis A is a nationally notifiable disease that requires reporting to public health authorities. The median reporting time to national surveillance is approximately 33 days 2, making it one of the slower-reported notifiable diseases, though local reporting requirements are typically more immediate.

Clinical Pitfall

Common mistake: Assuming only meningococcal meningitis is reportable. In reality, all bacterial meningitis cases must be reported, though the specific reporting category depends on the causative organism 1. Failure to report can compromise outbreak detection, particularly in high-risk settings like sporting events where attendees disperse to multiple locations within the incubation period 3.
