SARS-COV-2 γ variant acquires spike P681H or P681R for improved viral fitness

The paper investigates how the SARS-CoV-2 gamma variant acquires spike mutations P681H and P681R to improve viral fitness and generate subvariants with varying virulence.

SARS-COV-2 C.1.2 variant is highly mutated but may possess reduced affinity for ACE2 receptor

The paper analyzes the C.1.2 SARS-CoV-2 variant, identifying it as highly mutated with potential reduced ACE2 receptor affinity due to spike Y449H substitution.

δ1 variant of SARS-COV-2 acquires spike V1176F and yields a highly mutated subvariant in Europe

The paper identifies the δ1F subvariant of SARS-COV-2, which acquires spike V1176F and additional mutations, and highlights its evolutionary significance.
