The resurgence of invasive meningococcal disease caused by Neisseria meningitidis serogroup W with sequence type ST-11 (cc11) was observed in Madagascar in 2015-2016. Three cases were investigated in this study. Molecular characterization of the strains suggests the local transmission of a single genotype that may have been circulating for years.
