However, on July 9, Public Health England reported that the Delta variant in England had a case fatality rate (CFR) of 0.2%, while the Alpha variant's case fatality rate was 1.9%, although the report warns that "case fatality rates are not comparable across variants as they have peaked at different points in the pandemic, and so vary in ...
Alphacoronaviruses (Alpha-CoV) are members of the first of the four genera (Alpha-, Beta-, Gamma-, and Delta-) of coronaviruses. They are positive-sense, single-stranded RNA viruses that infect mammals, including humans. They have spherical virions with club-shaped surface projections formed by trimers of the spike protein, and a viral envelope.
While the alpha and beta genera are derived from the bat viral gene pool, the gamma and delta genera are derived from the avian and pig viral gene pools. [1] Recombination appears to be common among deltacoronaviruses. [2] Recombination occurs frequently in the viral genome region that encodes the host receptor binding protein.
Delta variant is 'more transmissible and it can break through the vaccine' Though vaccination numbers in the country have improved as of late, the overall rollout has still been impeded by vaccine ...
With the Delta variant driving a surge in COVID-19 infections, health officials warn the threat of the contagious variant is ‘serious’ as infected patients crowd hospital beds in hard-hit regions.

Lineage B.1.617 is a lineage of SARS-CoV-2, the virus that causes COVID-19. [1] It first came to international attention in late March 2021 after the newly established INSACOG performed genome sequencing on positive samples throughout various Indian states.
