Preprint: Emergence and spread of a B.1.1.28-derived lineage with Q675H and Q677H Spike mutations in Uruguay
In a previous study we found a sublineage B.1.1.28+Q675H+Q677H with local transmission in Rocha, a Uruguayan department bordering Brazil. More...
Preprint: Prevalent evidence of coronavirus variant B.1.617.2 Delta in post-vaccinated individuals in India
“We sequenced all samples of vaccination-breakthrough cases at NCDC, Delhi, over the period of the study. More...
Europe: B.1.620 coronavirus variant – definitely one to watch
“Last month, Gytis Dudas was tracking a concerning new coronavirus variant that had triggered an outbreak of COVID-19 in his native Lithuania and appeared sporadically elsewhere in Europe and in the United States. More...
Household transmission of R.1 coronavirus lineage with spike E484K mutation in Japan
In this study, we conducted genetic surveillance and identified R.1 lineage harboring E484K mutation in RBD by whole genome sequencing. More...
USA: large covid-19 outbreak in Kentucky with R.1 coronavirus lineage variant after vaccine breakthrough with Pfizer
The Kentucky Department for Public Health and a local health department investigated a COVID-19 outbreak in a skilled nursing facility that occurred after all residents and health care personnel had been offered vaccination. More...
UK coronavirus variant B.1.1.7 may not have evolved spontaneously in the UK or within human populations
“Here we analyzed 454,443 SARS-CoV-2 spike genes/proteins and 14,427 whole-genome sequences. More...
Brazil: novel coronavirus variant VUI-NP13L reported along with 2 cases of coinfection with B.1.1.28
“We were the first to identify two independent events of co-infection caused by the occurrence of B.1.1.28 (E484K) with either B.1.1.248 or B.1.91 lineages. More...
Identification of a novel coronavirus lineage harboring E484Q and N501T spike mutations in Minas Gerais, Southeast Brazil
We report a cluster of two sequences characterized by a unique array of 18 mutations, including new non-synonymous changes in the same critical spike amino acid positions, E484Q and N501T. More...
New SARS-CoV-2 coronavirus lineage that shares mutations with known Variants of Concern (VOC) reported in 20 states across USA
We report a SARS-CoV-2 lineage that shares N501Y, P681H, and other mutations with known variants of concern, such as B.1.1.7. More...
Recombination and lineage-specific mutations linked to the emergence of SARS-CoV-2 coronavirus
In this work, we reconstruct the evolutionary events that have accompanied the emergence of SARS-CoV-2, with a special emphasis on the RBD and its adaptation for binding to its receptor, human ACE2 (hACE2). More...
