Persistence of the T12 Vibrio cholerae O1 lineage in West Africa: Insights from a Regional Sequencing Workshop

We sequenced 46 Vibrio cholerae isolates from Cameroon, Niger, and Nigeria, 37 of which were from 2018–2019. These sequences belong to the T12 lineage observed in the region since 2009, suggesting continuous transmission. Data were generated during a workshop in Nigeria, providing a model for future regionally coordinated surveillance efforts. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement Funding for this project was provided by Bill and Melinda Gates Foundation OPP1195157. ### Author Declarations I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.
