摘　　要：目的新型冠状病毒(SARS-CoV-2)全球大流行以来,中国内地报道了多起SARS-CoV-2污染进口冷链食品引起的本土新冠疫情,分析此类疫情的特点和传播概况,可以为今后类似疫情防控提出相应建议。方法收集SARS-CoV-2污染进口冷链食品引起本土新冠疫情文献、官方新闻报道等信息,整理和分析相应数据。结果2020年6月至2022年11月,共检索到此类疫情20起,包含1646例病例,涉及9个省(自治区、直辖市)。其中,2020年10起,2021年3起,2022年7起;病例数规模在200例及以上共3起。结论新冠全球大流行以来中国内地检索到的20起进口冷链食品相关本土新冠疫情均为冷链从业人员接触进口冷链食品或其外包装感染引起,且大部分(75%)引起了后续社区传播,但是在中国内地集中监管仓建设等各种有力控制措施下,此类疫情数量和持续时间均呈下降趋势。Objective Since the global pandemic of coronavirus disease 2019(COVID-19)broken,a series of local outbreaks caused by the contamination of imported cold chain food by SARS-CoV-2 had been reported in China’s Mainland.To provide corresponding suggestions for the prevention and control of similar epidemics in the future,the characteristics and spread of such epidemics was analyzed.Methods All the literature,official news reports and other materials on the local COVID-19 outbreak caused by SARS-CoV-2 contaminated imported cold chain food was collected,and the corresponding data was sort out and analyzed.Results From June 2020 to November 2022,a total of 20 local COVID-19 outbreaks related to imported cold chain products were reported,with a total of 1646 cases,involving 9 provinces.Among the 20 outbreaks,there were 10 outbreaks in 2020,3 outbreaks in 2021,and seven outbreaks in 2022,and 3 outbreaks had 200 or more cases.Conclusion Since the global pandemic of COVID-19 broken,the 20 local outbreaks related to imported cold-chain food traced domestically were caused by cold-chain workers who were infected by contact with imported cold-chain food or their overpacks,and most of local outbreaks(75%)caused subsequent community transmission.But under various effective control measures such as the construction of centralized supervision warehouses in China's mainland,the number and duration of local outbreaks related to imported cold chain food have shown a downward trend.
