Abstract

During the COVID-19 pandemic, a series of outbreaks and related investigations have indicated that the virus can be transmitted via cold-chain environment media. The causal relationship between the cold chain and the introduction and spread of viruses has been established. However, due to its stealthy nature, cold-chain environment media is often overlooked. Herein, we aim to provide a systematic review of the existing evidences and logical chains of virus transmission and introduction through cold-chain, from the perspectives of epidemiological investigations, laboratory researches, and molecular epidemiological evidences of cold-chain-related outbreaks. Additionally, scientific evidences also include the survival capacity of the virus in cold-chain environments, as well as modeling of virus transmission and risk assessment. These evidences and the logical framework related to cold-chain transmission put forward the initiation of cold-chain-based epidemiology (CCBE) as one of the important portions of the epidemiology of infectious diseases. Close multidisciplinary collaboration in this field will be essential for the preparation of future pandemics.

基于冷链的流行病学：严重急性呼吸系统综合征冠状病毒2型引入和传播的科学证据和逻辑

在新冠肺炎大流行期间，一系列疫情和相关调查表明，该病毒可以通过冷链环境介质传播。冷链与病毒的引入和传播之间的因果关系已经确立。然而，由于其隐蔽性，冷链环境媒体往往被忽视。本文旨在从流行病学调查、实验室研究和冷链相关疫情的分子流行病学证据等角度，对病毒通过冷链传播和引入的现有证据和逻辑链进行系统综述。此外，科学证据还包括病毒在冷链环境中的生存能力，以及病毒传播模型和风险评估。这些证据和与冷链传播相关的逻辑框架提出了基于冷链的流行病学（CCBE）作为传染病流行病学的重要组成部分之一的开端。这一领域的密切多学科合作对于为未来的流行病做准备至关重要。
