Serogroup B Invasive Meningococcal Disease in Older Adults Identified by Genomic Surveillance, England, 2022-2023.

Abstract

We report a cluster of serogroup B invasive meningococcal disease identified via genomic surveillance in older adults in England and describe the public health responses. Genomic surveillance is critical for supporting public health investigations and detecting the growing threat of serogroup B Neisseria meningitidis infections in older adults.
