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...
A SARS-CoV-2 coronavirus lineage A variant (A.23.1) with altered spike has emerged and is dominating the current Uganda epidemic
February 2021: We report here newly emerging A sub-lineages, A.23 and A.23.1, encoding replacements in the spike protein, nsp6, ORF8 and ORF9, with A.23.1 the major virus lineage now observed in Kampala. 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...

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...
Israel: new coronavirus variant found, has infected hundreds of people
Scientists have discovered an Israeli coronavirus variant, and believe there are hundreds of cases of the mutation in the north, south and center of the country — but they don’t believe it poses a challenge to vaccine effectiveness. More...
