Rc-o319 is a bat-derived strain of severe acute respiratory syndrome–related coronavirus collected in Little Japanese horseshoe bats (Rhinolophus cornutus) from sites in Iwate, Japan.^[1]^[2] Its has 81% similarity to SARS-CoV-2 and is the earliest strain branch of the SARS-CoV-2 related coronavirus.
