UK: B.1.617 found in 24% of coronavirus sequences in Bolton, mostly new Delta VOC B.1.617.2
Following a rise in cases in the UK and evidence of community transmission, PHE has reclassified B.1.617.2 as a Variant of Concern (VOC). More...
UK government poised to declare Delta coronavirus B.1.617 a Variant of Concern or VOC
The UK government is thought to have detected more than 40 clusters of the Indian Covid variant B.1.617 in the UK, and is on the verge of declaring it a “variant of concern”.
India: The stunning rise of the B.1.617.2 [Delta] coronavirus variant
Professor Christina Pagel: [B.1.617.2] rapidly became dominant in India and, again, the sequenced data there is sparse, but early modelling shows that it might well be more transmissible than our B.1.1.7 Kent strain. More...

Examination of the SARS-CoV-2 sequences revealed that both patients were infected with variant viruses. More...
Nepal: new coronavirus daily case rate still closely tied to India’s outbreak
Nepal’s daily coronavirus case is still closely tracking that of its neighbour India, Nepal may also be in need of assistance with medical supplies and equipment to alleviate suffering within the next 7 days. 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...
France: Breton variant B.1.616 – 37 cases & 16 deaths with just 9% of cases detected by first RT-PCR coronavirus test
As of 04/21, 37 confirmed cases of infection with the 20C / 655Y [B.1.616] variant have been reported in France, including 34 in Brittany and 3 in other regions in people linked to the area of circulation of the virus in Brittany (made up of several urban communities around Lannion, Guingamp, Saint-Brieuc, Paimpol).

UK SAGE: Lab studies suggest that the N501Y spike protein mutation increases binding to rat and mouse ACE2 leading to viral replication
A report issued by the UK government’s Scientific Advisory Group for Emergencies (SAGE) found the likelihood that a variant of concern (VOC) that has arisen in humans could infect a rodent and then spread among the animals is high. More...
India: Over 50% of coronavirus genome samples in some Maharahstra cities are “double mutant” B.1.617
Sujeet Singh, director of the Indian National Centre for Disease Control (NCDC), said that in Maharashtra, the B.1.617 variant was found in proportions of over 50% in many cities. More...
NEJM: In two coronavirus vaccine breakthrough cases “examination of the SARS-CoV-2 sequences revealed that both patients were infected with variant viruses” .. “neither sequence precisely fit any known clade”
Examination of the SARS-CoV-2 sequences revealed that both patients were infected with variant viruses. More...
