Now there is more mystery regarding the history of SARS-CoV-2 before the pandemic in case of China.
Previously, SARS-CoV-2 genomic sequences corresponding to both A,B lineage as well as USA-WA-1 was found within samples of Antarctic soil that were extracted and sent for sequencing in December 2019, 101 runs prior to the first sequencing of samples taken from “viral pneumonia of unknown etiology” patients from the Huanan seafood market by the Wuhan Institute of Virology. It appeared that these samples were not the only samples that were taken from China in 2019, that contained sequences derived from SARS-CoV-2 and were decidedly NOT linked to the wildlife trade in any way.
