U.S. CDC: Increase in Invasive Serogroup Y Meningococcal Disease in the United States
U.S. CDC is reporting an increase in invasive meningococcal disease in the U.S. in 2024, mainly attributable to Neisseria meningitidis serogroup Y. Most cases involve a single sequence type, ST-1466. Most of the patients are between 30-60 years old, are Black or African American, or are living with HIV. In addition, most cases caused by this strain had a clinical presentation other than meningitis, such as bacteremia and septic arthritis.
