摘要
The origin of SARS-CoV-2 is still an unresolved mystery.In this study,we systematically reviewed the main research progress of wild animals carrying virus highly homologous to SARS-CoV-2 and analyzed the natural foci characteristics of SARS-CoV-2.The complexity of SARS-CoV-2 origin in wild animals and the possibility of SARS-CoV-2 long-term existence in human populations are also discussed.The joint investigation of corona virus carried by wildlife,as well as the ecology and patho-ecology of bats and other wildlife,are key measures to further clarify the characteristics of natural foci of SARS-CoV-2 and actively defend against future outbreaks of emerging zoonotic diseases.
