Recent spillover transmission events. A native reservoir serves as the source of a virus to other host species, in which it could be virulent. This accidental cross-species transmission (i.e., spillover transmission) (red arrows), occurs between host species without evolutionary relatedness. Spillover transmission between two genetically unrelated species has been documented in recent emerging infectious where a pathogen from an original wildlife host (left) is transmitted (primary spillover; red arrows on the left) to another wildlife or domestic species (middle), and from them to a human (secondary spillover; right). SADS-CoV: swine acute diarrhea syndrome coronavirus. SARS-CoV: severe acute respiratory syndrome coronavirus. MERS-CoV: Middle-East respiratory syndrome. SARS-CoV-2: severe acute respiratory syndrome coronavirus 2
