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.

Genomic Mutations and Changes in Protein Secondary Structure and Solvent Accessibility of SARS-CoV-2 (COVID-19 Virus)

TL;DR: Analysis of genomic mutations in the coding regions of SARS-CoV-2 and their probable protein secondary structure and solvent accessibility changes, which are predicted using deep learning models suggest that mutation D614G in the virus spike protein, which has attracted much attention from researchers, is unlikely to make changes in proteinsecondary structure and relative solvent accessibility.

Predicting mammalian hosts in which novel coronaviruses can be generated.

TL;DR: In this article, a meta-ensemble of similarity learners from three complementary perspectives (viral, mammalian and network) is deployed to predict which mammals are hosts of multiple coronaviruses, and the results demonstrate the large underappreciation of the potential scale of novel coronavirus generation in wild and domesticated animals.

An analysis of COVID-19 spread based on fractal interpolation and fractal dimension

TL;DR: A reconstruction of the epidemic curves from the fractal interpolation point of view is proposed to retrieve missing pieces of information due to insufficient testing and predict the evolution of the disease.

Modelling scenarios of the epidemic of COVID-19 in Canada

TL;DR: P predictive modelling of COVID-19 in general, and efforts within the Public Health Agency of Canada to model the effects of non-pharmaceutical interventions on transmission of SARS-CoV-2 in the Canadian population to support public health decisions, suggest applying NPIs with intensity high enough to cause the epidemic to die out is the preferred choice.

Does life expectancy, death rate and public health expenditure matter in sustaining economic growth under COVID-19: Empirical evidence from Nigeria?

TL;DR: Empirical results show that a 1% increase in life expectancy and death rate increases and decreases economic growth by 3.85 and 1.84%, respectively, which suggests the need for Health Policymakers in Nigeria to implement active strategies that reduce the death rate.

A pneumonia outbreak associated with a new coronavirus of probable bat origin

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.

A new coronavirus associated with human respiratory disease in China.

TL;DR: Phylogenetic and metagenomic analyses of the complete viral genome of a new coronavirus from the family Coronaviridae reveal that the virus is closely related to a group of SARS-like coronaviruses found in bats in China.

An interactive web-based dashboard to track COVID-19 in real time.

TL;DR: The outbreak of the 2019 novel coronavirus disease (COVID-19) has induced a considerable degree of fear, emotional stress and anxiety among individuals around the world.

Cryo-EM structure of the 2019-nCoV spike in the prefusion conformation.

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.
