SARS-CoV-2 is the virus responsible for the global COVID19 pandemic. We review what is known about the origin of this virus, detected in China at the end of December 2019. The genome of this virus mainly evolves under the effect of point mutations. These are generally neutral and have no impact on virulence and severity, but some appear to influence infectivity, notably the D614G mutation of the Spike protein. To date (30/09/2020) no recombination of the virus has been documented in the human… Expand

Heterogeneity of SARS-CoV-2 virus produced in cell culture revealed by shotgun proteomics and supported by genome sequencing
How shotgun proteomics can be useful for rapidly monitoring the evolution of the SARS-CoV-2 virus is documented and found that cell culture induces significant changes that are translated at the protein level, such changes being detectable by tandem mass spectrometry. Expand

A twice-accelerated viral population expansion, followed by a temporary setback, was inferred during the early stages of the pandemic in Southeast Asia, illustrating the phylogeography and phylodynamics of SARS-CoV-2 circulating inoutheast Asia. Expand
Climate Induced Virus Generated Communicable Diseases: Management Issues and Failures
Human diseases caused by various groups of pathogens have been explained with its etiology, epidemiology and treatment, and effect of climatic changes on parasites and pathogens has been demarcated with rising incidences of diseases. Expand


Emergence of genomic diversity and recurrent mutations in SARS-CoV-2
The results are in line with previous estimates and point to all sequences sharing a common ancestor towards the end of 2019, supporting this as the period when SARS-CoV-2 jumped into its human host. Expand
On the origin and continuing evolution of SARS-CoV-2
The results suggest that the development of new variations in functional sites in the receptor-binding domain of the spike seen in SARS-CoV-2 and viruses from pangolin SARSr-CoVs are likely caused by mutations and natural selection besides recombination. Expand
Introductions and early spread of SARS-CoV-2 in France
Phylogenetic analysis identified several early independent SARS-CoV-2 introductions without local transmission, highlighting the efficacy of the measures taken to prevent virus spread from symptomatic cases and calls for further efforts with inclusion of asymptomatic infections. Expand
Evolutionary origins of the SARS-CoV-2 sarbecovirus lineage responsible for the COVID-19 pandemic
SARS-CoV-2 itself is not a recombinant of any sarbecoviruses detected to date, and its receptor-binding motif appears to be an ancestral trait shared with bat viruses and not one acquired recently via recombination. Expand
A dynamic nomenclature proposal for SARS-CoV-2 lineages to assist genomic epidemiology
A rational and dynamic virus nomenclature that uses a phylogenetic framework to identify those lineages that contribute most to active spread and is designed to provide a real-time bird’s-eye view of the diversity of the hundreds of thousands of genome sequences collected worldwide. Expand
The emergence of SARS-CoV-2 in Europe and North America
When, where, and how the earliest sustained severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission networks became established in Europe and North America are elucidated. Expand
The proximal origin of SARS-CoV-2
It is shown that SARS-CoV-2 is not a laboratory construct or a purposefully manipulated virus, and scenarios by which they could have arisen are discussed. Expand
Discovery and Genomic Characterization of a 382-Nucleotide Deletion in ORF7b and ORF8 during the Early Evolution of SARS-CoV-2
A robust antibody response to ORF8 has been observed in SARS-CoV-2 infection, suggesting that the emergence of ORF7b/8 deletions may be due to immune-driven selection and that further deletion variants may emerge during the sustained transmission of Sars-Cov-2 in humans. Expand
Cytosine drives evolution of SARS‐CoV‐2
In this article, we show, in the specific case of SARS-CoV-2, that the role of cytosine-based metabolites used as cell growth coordinators is central to understanding both innate antiviral immunityExpand
The Impact of Mutations in SARS-CoV-2 Spike on Viral Infectivity and Antigenicity
Most variants with amino acid change at receptor binding domain were less infectious but variants including A475V, L452R, V483A and F490L became resistant to some neutralizing antibodies, while deletion of both N331 and N343 glycosylation drastically reduced infectivity, revealing the importance of gly cosylation for viral infectivity.
