Bat SARS-like coronavirus WIV1 (Bat SL-CoV-WIV1), also sometimes called SARS-like coronavirus WIV1, is a strain of severe acute respiratory syndrome–related coronavirus (SARSr-CoV) isolated from Chinese rufous horseshoe bats in 2013 (Rhinolophus sinicus).[1][2] Like all coronaviruses, virions consist of single-stranded positive-sense RNA enclosed within an envelope.[3]

Zoonosis
The discovery confirms that bats are the natural reservoir of SARS-CoV. Phylogenetic analysis shows the possibility of direct transmission of SARS from bats to humans without the intermediary Chinese civets, as previously believed.[4]
