Results A total of 13 230 specimens of all kinds were detected. Five strains of V. cholerae were detected, the positive rate was 0.038%. The stool specimens were not detected. The positive rates of seawater samples and water samples were 0.119% 4/3 363) and 0.049% (1/2 042) respectively. The highest positive rate was found in seawater samples. Five strains of V. cholerae were non-toxigenic, including 2 Ogawa type O1 and 0 type rice 3 strains. Conclusion The key to controlling the spread of cholera is to strengthen the management of gut clinics and technical training, strengthen the monitoring of sea water products and farms, timely detection and management of sources of infection, and improvement of the positive detection rate of V. cholerae.
