SARS-CoV-2 is a global challenge due to its ability to mutate into variants that spread more
rapidly than the wild-type virus. Because the molecular biology of this virus has been studied …

When BA. 2.86 joined the SARS-CoV-2 Omicron family last summer, it grabbed pandemic
trackers' attention because it was so different from its progenitor, BA. 2. Compared with BA …

Rapidly spreading SARS-CoV-2 variants present not only an increased threat to human
health due to the confirmed greater transmissibility of several of these new strains but, due to …

Abstract In late 2022, SARS-CoV-2 Omicron subvariants have become highly diversified,
and XBB is spreading rapidly around the world. Our phylogenetic analyses suggested that …

SARS-CoV-2 emergent variants are characterized by increased viral fitness and each shows
multiple mutations predominantly localized to the spike (S) protein. Here, amide …

SARS-CoV-2 evolves rapidly in part because of its high mutation rate. Here, we examine
whether this mutational process itself has changed during viral evolution. To do this, we …

On January 10, 2020, the first genomic sequence of the severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) isolated from a patient in Wuhan, China, was posted online. As …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) became a global health
crisis after its emergence in 2019. Replication of the virus is initiated by binding of the viral …

In this issue of Cell, Korber et al. found that a SARS-CoV-2 variant in the spike protein
D614G rapidly became dominant around the world. Although clinical and in vitro data …

Receptor recognition is a major determinant of viral host range, as well as infectivity and
pathogenesis. Emergences have been associated with serendipitous events of adaptation …
