These infections, caused by a certain strain of Neisseria meningitidis bacteria, are associated with higher fatality rates than usual.
Cases of meningococcal infections are occurring in middle-aged adults, unlike the typical pattern seen in babies or adolescents and young adults.
The bacteria can spread through respiratory and throat secretions, primarily through kissing, coughing, sneezing, or close contact with infected individuals.
In 2023, the US saw 422 cases of meningococcal disease caused by various bacteria, with ST-1466 strain in the Y subgroup being predominant.
