Evolutionary dynamics and global spread of macrolide-resistant Bordetella pertussis during the post-pandemic pertussis resurgence

This unified global genomic analysis demonstrates both shared and region-specific post-pandemic shifts in B. pertussis populations. The dominance of the MR-MT28 sublineage in China, together with its international dissemination and ongoing diversification, represents a growing public health concern and underscores the need for coordinated global genomic surveillance.
