Pre-2019 Antarctic specimens with SARS-CoV-2 sequences found in Hefei, China laboratories are likely contamination from local COVID-19 specimens from Jan 2020 and later

SARS-CoV-2 genome sequences identified in specimens collected in the Antarctica before 2019 have a three SNV signature also found uniquely in clinical COVID specimens from early 2020 from Hefei Province, China and are most likely simple clinical lab-research lab cross contamination.
