Identification of a new B.1.1.33 SARS-CoV-2 Variant of Interest (VOI) circulating in Brazil with mutation E484K and multiple deletions in the Spike protein
Here, we report a new SARS-CoV-2 VOI derived from lineage B.1.1.33, preliminary designated as PANGO lineage N.10, harboring 14 lineage defining mutations. More...
L452R mutation is present in more than 400 SARS-CoV-2 coronavirus genomes isolated from over 20 countries
Scientists have examined the Nextstrain and GISAID databases and found that the L452R mutation is present in more than 400 SARS-CoV-2 genomes isolated from over 20 countries. More...
Transmission of SARS-CoV-2 coronavirus in domestic cats may have accelerated the fixation of S H655Y
Transmission of SARS-CoV-2 in cats involved a narrow bottleneck, with new infections founded by fewer than ten viruses. More...
Rapid rise of coronavirus SARS-CoV-2 spike mutation T478K found in Mexico and several European countries
We report the distribution of the Spike mutation S:T478K and its recent growth in prevalence in the SARS-CoV-2 population. More...
Canada: coronavirus variant P.1 outbreak spreads to Alberta
“We are currently investigating a significant #COVID19AB outbreak in Alberta involving P.1 variants of concern (the variant that originated in Brazil), linked to a returning traveller.” More...
Denmark: 2 cases of B.1.1.7 coronavirus variant found with E484K mutation
Denmark has found the first two cases of the UK coronavirus variant B.1.1.7, which has been mutated to have reduced sensitivity to antibodies, says Minister of Health Magnus Heunicke (S). More...
Canada: largest outbreak of P.1 coronavirus variant outside of Brazil discovered in British Columbia
The coronavirus variant that forced the Whistler Blackcomb ski resort to close is spreading rapidly in B.C. More...
Colombia: novel highly divergent coronavirus SARS-CoV-2 lineage with the Spike substitutions L249S and E484K, assigned to the B.1.111 lineage
Here we report a novel and highly divergent lineage with 21 characteristic mutations, including 10 non-synonymous, 8 synonymous and 3 mutations in non-coding regions (5’and 3’ UTR and intergenic region). More...
France: novel coronavirus SARS-CoV-2 variant derived from Clade 19B with spike substitutions N501Y, L452R, and H655Y – named HMN.19B or Henri Mondor variant
We report a novel severe acute respiratory syndrome coronavirus 2 variant derived from clade 19B (HMN.19B variant or Henri Mondor variant). More...
Emergence of N antigen SARS-CoV-2 genetic variants escaping detection of antigenic coronavirus tests
While conducting a large validation study on the Abbott Panbio™ COVID-19 Ag test, we noticed that some swab samples failed to generate a positive result in spite of a high viral load in Rt-PCR assays. More...
