Bat SARS-like coronavirus WIV1, (Bat SL-CoV-WIV1) also sometimes called SARS-like coronavirus WIV1, is a newly identified CoV isolated from Chinese rufous horseshoe bats. The discovery confirms that bats are the natural reservoir of the SARS virus. Phylogenetic analysis shows the possibility of direct transmission of SARS from bats to humans without the intermediary Chinese civets, as previously believed. It is a single-stranded, enveloped, positive-sense RNA betacoronavirus.
