Abstract
ARS-COV-2 has strong infectivity, fast transmission speed and peculiar transmission route. COVID-19 broke out all over the world in a very short time [1,2]. It was reported in Wuhan, China, in December 2019, mainly spread rapidly from person to person, and interpersonal communication mainly occurred in families [3]. This shows that close contact communication between individuals is one of the most important ways of transmission [4]. China has adopted strict quarantine measures and basically controlled the epidemic within a few months. Since July 2020, SARS-COV-2 has been detected frequently in imported cold chain food in China The spread of SARS-COV-2 carried by imported cold chain food immediately aroused widespread concern This paper analyzes and discusses the long-term survival of the virus in cold chain food and its cross-border transmission. It reminds that SARS-COV-2 can be directly transmitted to people by cold chain food packaging, and relevant personnel should pay attention to self-protection and isolation to prevent infection and transmission.
