Abstract:
Objective:To explore the epidemiological characteristics and spatiotemporal clustering of foodborne infection of Vibrio ( V.) parahaemolyticus in Ningbo, Zhejiang Province, from 2014 to 2022, and provide reference and evidence for the prevention and control of related diseases. Methods:The incidence data on of foodborne infection of V. parahaemolyticus in Ningbo from 2014 to 2022 were collected from Ningbo Foodborne Disease Surveillance System, and the case counts and the positive rates in different districts (counties, cities) were calculated. Spatial autocorrelation analysis and spatiotemporal scanning analysis were conducted to analyze the spatiotemporal clustering of the diseases. Results:A total of 1 822 cases of foodborne infection of V. parahaemolyticus were reported in Ningbo from 2014 to 2022, with an overall positive rate of 3.78%. Spatial autocorrelation analysis showed that the positive rate of foodborne infection of V. parahaemolyticus in Ningbo was unevenly distributed from 2014 to 2022, Ninghai was a high-high clustering area, while Zhenhai was a high-low clustering area, and Jiangbei was a low-low clustering area. The annual incidence was high during July-September. Spatiotemporal scanning analysis found one class Ⅰ spatiotemporal clustering area and three class Ⅱ spatiotemporal clustering areas, with the class Ⅰ spatiotemporal clustering area being observed in Jiangbei and Zhenhai from 2019 to 2022. Conclusions:Spatiotemporal clustering of foodborne infection of V. parahaemolyticus existed in Ningbo from 2014 to 2022, with an annual high incidence period from July to September. The key areas for the prevention and control of foodborne infection of V. parahaemolyticus are coastal districts (counties, cities) in Ningbo.
