Few major outbreaks of coronavirus disease 2019 (COVID-19) have occurred in China after major non-pharmaceutical interventions and vaccines have been deployed and implemented. However, sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China.. In July 2020, a COVID-19 outbreak occurred in Dalian, China. The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact. Virus contaminated paper surfaces could maintain infectivity for at least 17-24 days at -25 ℃. Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population. Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods. Several measures to prevent the introduction of the virus via cold-chain goods can be implemented.
在中国实施重大非药物干预措施并部署和接种疫苗后，2019年冠状病毒病（COVID-19）的大规模暴发已很少发生。然而，中国几个城市报告了一些很可能与冷链产品有关的散发病例。2020年7月，中国大连发生了一起COVID-19疫情。对此次疫情的调查有力地表明，感染源来自入境卸货人员接触期间被COVID-19病毒污染的冷冻海鲜包装。在-25℃下，病毒污染的纸面可保持传染性至少17-24天。接触被COVID-19病毒污染的表面是将病毒传播给易感人群的一个潜在途径。没有COVID-19本土传播的国家应考虑针对入境旅客和进口货物引入预防策略。可以实施多项措施来防止病毒通过冷链商品传入。
