# Emergence and Prevalence of Vibrio cholerae O1 Sequence Type 75 Clonal Complex, Fujian Province, China, 2009–2023

## TL;DR

This study tracks the spread of a specific type of Vibrio cholerae in Fujian, China, from 2009 to 2023, highlighting the rise of a new strain.

## Contribution

The study identifies the emergence and dominance of Vibrio cholerae O1 ST75 clonal complex in Fujian Province from 2020 onwards.

## Key findings

- Sequence type 75 clonal complex has continuously emerged since 2020.
- ST1480 and ST182 strains have dominated in the region.
- ST1480 strains show widespread transmission patterns.

## Abstract

We investigated the molecular epidemiology of Vibrio cholerae O1 in Fujian Province, China, during 2009­–2023. Sequence type (ST) 75 clonal complex has emerged continuously since 2020, and ST1480 and ST182 have dominated. ST1480 strains appear to have widespread transmission. To monitor V. cholerae evolution, continued global genomic surveillance is needed.
