T1 - Possible Bat Origin of Severe Acute Respiratory Syndrome Coronavirus 2 T2 - Emerging Infectious Disease journal PY - 2020 VL - 26 IS - 7 SP - 1542 SN - 1080-6059 AB - We showed that severe acute respiratory syndrome coronavirus 2 is probably a novel recombinant virus. Its genome is closest to that of severe acute respiratory syndrome–related coronaviruses from horseshoe bats, and its receptor-binding domain is closest to that of pangolin viruses. Its origin and direct ancestral viruses have not been identified.
