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 (SARS-CoV) isolated from Chinese rufous horseshoe bats (Rhinolophus sinicus).[1][2] Like all coronaviruses, virions consist of single-stranded positive-sense RNA enclosed within an envelope.[3]
