This outbreak was associated with a large seafood and animal market [61]. Further investigations are ongoing to determine the origin of the infection. To date, many reports have described possible original and intermediate hosts (Fig. 1 ). Researchers found that the SARS-CoV-2 showed a higher sequence homology to Bat-CoV-RaTG13 that was previously detected in Rhinolophus affinis from Yunnan Province than Bat-SL-CoVZC21 and Bat-SL-CoVZC45, which suggested that the Chinese chrysanthemum bat is the origin of SARS-CoV-2. More recently, the pangolin was believed to be the likely intermediate host due to the fact that there appeared to be approximately 99% sequence homology between SARS-Co V-2 and the consensus sequence derived from \u003e1000 metagenomic samples from the pangolin species [62].\nFig. 1 The origin and inter-host timeline of SARS-CoV-2.
