Genome Sequences from a Reemergence of Vibrio cholerae in Haiti, 2022 Reveal Relatedness to Previously Circulating Strains

After more than 3 years without a documented cholera case, the Republic of Haiti reported its first resurgent case on 30 September 2022 (1–3). As of 18 February 2023, more than 27,000 cholera cases have been hospitalized and 594 deaths confirmed from all 10 departments (4). Here, we describe Vibrio cholerae isolates first characterized by the Laboratoire National de Santé Publique (LNSP) and include both genotypic and phenotypic antimicrobial resistance profiles. Whole-genome sequencing (WGS) analysis was compared with recently circulating cholera toxin-producing V. cholerae O1 in a maximum likelihood phylogeny.
