According to the report, COVID-19 introduction through an intermediate host is "likely to very likely," introduction through cold/food chain products is "possible," and introduction through a laboratory incident is "extremely unlikely."
报告称，新冠病毒经中间宿主引入人类的可能性为"比较可能"到"非常可能"，也"可能"通过冷链食品引入人类，通过实验室引入人类"极不可能"。

The experts also put forward a series of recommendations for future research: Developing a comprehensive information database, conducting further retrospective and systematic research around earlier cases and possible hosts, and analyzing the different role of the cold chain in the possible introduction and spread of the virus.
报告提出了下步研究的建议，包括建立全球统一的数据库，围绕早期病例和可能宿主开展进一步回顾性系统研究，分析冷链在病毒引入和传播过程中的作用等。
