CDC has issued a Health Alert Network Advisory on a rapid increase in meningococcal disease, mainly attributable to Neisseria meningitidis serogroup Y. The increase disproportionately occurs in people ages 30–60 years (65%), Black or African American people (63%), and people with HIV (15%). It frequently has a clinical presentation other than meningitis: 64% presented with bacteremia, and at least 4% presented with septic arthritis. The 18% 2024 case-fatality rate is 64% higher than the historical rate. CDC recommends:
- Heightened suspicion for meningococcal disease, particularly among disproportionately affected populations,
- Awareness that patients may present without symptoms typical of meningitis, and
- Ensuring that all people recommended for meningococcal vaccination, including people with HIV, are up to date for meningococcal vaccines.
