Since June 2020, the re-emergence of coronavirus disease 2019 (COVID-19) epidemics in parts of China was linked to the cold chain, which attracted extensive attention and heated discussions from the public. According to the typical characteristics of these epidemics, we speculated a possible route of transmission from cold chain to human. A series of factors in the supply chain contributed to the epidemics if the cold chain were contaminated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), such as temperature, humidity, personal hygiene/protection, and disinfection. The workers who worked in the cold chain at the receiving end faced a higher risk of being infected when they were not well protected. Facing the difficult situation, China put forward targeted and powerful countermeasures to block the cold chain-related risk. However, in the context of the unstable pandemic situation globally, the risk of the cold chain needs to be recognized and evaluated seriously. Hence, in this review, we reviewed the cold chain-related epidemics in China, analyzed the possible mechanisms, introduced the Chinese experience, and suggested coping strategies for the global epidemic prevention and control.
自2020年6月以来，中国部分地区新型冠状病毒肺炎（COVID-19）疫情的再次出现与冷链有关，这引起了公众的广泛关注和热烈讨论。根据这些疫情的典型特征，我们推测了一种从冷链到人的可能传播途径。如果冷链被严重急性呼吸综合征冠状病毒2（SARS-CoV-2）污染，供应链中的一系列因素会导致疫情，如温度、湿度、个人卫生/防护和消毒等。在接收端从事冷链工作的工人在防护不佳时面临更高的感染风险。面对这一困难局面，中国提出了针对性强且有力的对策来阻断与冷链相关的风险。然而，在全球疫情形势不稳定的背景下，冷链风险需要得到认真认识和评估。因此，在本综述中，我们回顾了中国与冷链相关的疫情，分析了可能的机制，介绍了中国经验，并提出了全球疫情防控的应对策略。
