Risk assessment of global cholera epidemic in 2023

目的 2023年全球霍乱疫情呈现影响范围广、发病数量高的特点,在当前出入境人数稳步上升的情况下,评估霍乱病例输入我国的风险以及进一步引起本土传播的风险。方法 根据全球霍乱疫情监测数据、疫情传播影响因素和既往病例输入我国的情况等资料,定性评估病例输入我国的风险以及进一步引起本土传播的风险。结果 经评估认为,霍乱病例输入我国的风险为中风险,输入后可能引起本土聚集性疫情。结论 为防范霍乱疫情输入风险,口岸需加强疫情监测和风险评估,做好高风险国家和地区入境人员卫生检疫,加强应急准备工作和卫生监督,开展国际旅行者健康宣教。

Objective The global cholera epidemic in 2023 was characterized by wide spread and high case count.With the steady increase of entry-exit travelers,it is necessary to assess the risk for the importation of cholera into China and the potential of further local transmission.Methods Based on the global cholera surveillance data,factors affecting the spread of cholera,and incidence data of imported cholera in China,the risk for the importation of cholera into China and the potential of further local transmission were assessed qualitatively.Results The assessment indicated a moderate risk for the importation of cholera into China and possible local epidemics caused by imported cholera cases.Conclusion To prevent the importation of cholera,it is necessary for entry ports in China to strengthen disease surveillance and risk assessment,health quarantine for travelers from high-risk countries or regions,emergency preparedness and health supervision,and carry out health education for international travelers.
