Nels and Vincent discuss the identification of novel bat coronaviruses that shed light on the evolution of SARS-CoV-2, dating the first cases of COVID-19 to mid-November 2019, and recovery of deleted genome sequences from early in the Wuhan outbreak.
Nels and Vincent review evidence for recombinant SARS-CoV-2 genomes arising in the B.1.1.7 lineage within the United Kingdom.
Nels and Vincent review a preprint demonstrating that changes in the genomes of the SARS-CoV-2 variants B1.351 and P.1 allow the viruses to reproduce in mouse cells in culture and in laboratory mice.
Nels and Vincent consider evolution of antibody immunity to SARS-CoV-2, and update the situation on novel virus variants of concern with potentially altered fitness and reactivity with antibodies.
Nels and Vincent wrap up 2020 with a discussion of novel variants of SARS-CoV-2 that have emerged in the United Kingdom and South Africa, how to interpret the rapidly emerging genome sequence data and what to look for in the coming weeks as these variants spread across the globe.
Nels and Vincent discuss an opinion piece on 12 evolutionary insights into how the COVID-19 pandemic is shaping human nature, and prolonged SARS-CoV-2 reproduction in an immunosuppressed patient.
Nels and Vincent continue their discussion of SARS-CoV-2 evolution, including understanding recurrent mutations in the viral genome, and the potential for re-emergence of the virus from an animal reservoir.
Nels and Vincent continue their discussion of SARS-CoV-2 evolution, with a report that the coronavirus proofreading enzyme stimulates RNA recombination, and debunking the conclusion that a change in the viral spike glycoprotein is associated with increased human to human transmission.
Nels and Vincent continue their discussion of SARS-CoV-2 from an evolutionary viewpoint, including function of the furin cleavage site, whether Vervet cells are an informative system, another bat isolate, and a nomenclature to assist genomic epidemiology.
Nels and Vincent examine SARS-CoV-2 from an evolutionary viewpoint, examining what the spike glycoprotein sequence informs us about the origin of the virus.
