TLDR
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.Abstract:
SARS-CoV-2 is the seventh coronavirus known to infect humans; SARSCoV, MERS-CoV and SARS-CoV-2 can cause severe disease, whereas HKU1, NL63, OC43 and 229E are associated with mild symptoms6. Here we review what can be deduced about the origin of SARS-CoV-2 from comparative analysis of genomic data. We offer a perspective on the notable features of the SARS-CoV-2 genome and discuss scenarios by which they could have arisen. Our analyses clearly show that SARS-CoV-2 is not a laboratory construct or a purposefully manipulated virus.read more

TL;DR: Clinically, the diagnosis of this unprecedented illness, called coronavirus disease-2019 (COVID-19), becomes difficult because it shares many symptoms with other respiratory pathogens, including influenza and parainfluenza viruses; the advances, features, advantages, and limitations of different laboratory methods used for SARS-CoV-2 diagnosis are discussed.

The Coronaviruses of Animals and Birds: Their Zoonosis, Vaccines, and Models for SARS-CoV and SARS-CoV2
TL;DR: This review elaborates on the pathogenesis and the developed vaccines of most of the ubiquitous coronavirus' diseases, mainly bovine, dromedary camel, porcine, feline, canine, and avian coronaviruses, raising the prospect of effective vaccines for these diseases.
Journal ArticleDOI
A palindromic RNA sequence as a common breakpoint contributor to copy-choice recombination in SARS-COV-2.
TL;DR: This paper demonstrates by bioinformatic analysis that such recombinational events are facilitated by short oligonucleotide “breakpoint sequences”, similar to CAGAC, that direct recombination naturally to certain positions in the genome at the boundaries between blocks of RNA code and potentially RNA structure, providing a natural explanation for the biogenesis of SARS-CoV-2 over time and in the wild.

TL;DR: Identification and characterization of a new coronavirus (2019-nCoV), which caused an epidemic of acute respiratory syndrome in humans in Wuhan, China, and it is shown that this virus belongs to the species of SARSr-CoV, indicates that the virus is related to a bat coronav virus.

TL;DR: The authors show that this protein binds at least 10 times more tightly than the corresponding spike protein of severe acute respiratory syndrome (SARS)–CoV to their common host cell receptor, and test several published SARS-CoV RBD-specific monoclonal antibodies found that they do not have appreciable binding to 2019-nCoV S, suggesting that antibody cross-reactivity may be limited between the two RBDs.
