7 de jun. de 2023 · It is worth examining the efforts to discover the origins of SARS-CoV-2, the political obstacles, and what the evidence tells us. This evidence can help clarify the virus’s evolutionary path.
5 de abr. de 2023 · This Review explores the mechanisms that generate genetic variation in SARS-CoV-2, underlying the within-host and population-level processes that underpin these events.
16 de feb. de 2023 · SARS-CoV-2, as to the previously highly pathogenic human coronaviruses named SARS-CoV, the etiological agent of severe acute respiratory syndrome (SARS), has a zoonotic origin, although SARS-CoV-2 precise chain of animal-to-human transmission remains undefined.
The story of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a case in point. A paper published in July, 2020, traced the origins of SARS-CoV-2. The researchers concluded that it came from a virus with relatively generalist properties circulating in horseshoe bats.
