ZC45 andZXC21, sometimes known as theZhoushan virus,[1] are two bat-derived strains ofsevere acute respiratory syndrome–related coronavirus. They were collected fromleast horseshoe bats (Rhinolophus pusillus) by personnel from military laboratories in the Third Military Medical University (Chongqing, China) and the Research Institute for Medicine of Nanjing Command (Nanjing, China) between July 2015 and February 2017 from sites inZhoushan,Zhejiang,China, and published in 2018. These two virus strains belong to the clade ofSARS-CoV-2, the virus strain that causesCOVID-19, sharing 88% nucleotide identity at the scale of the complete virus genome.[2][3]
