SARS-CoV-2 Lambda Variant: The New Kid on the Block

The COVID-19 pandemic has been marked by the ongoing emergence of new genetic variants. Although SARS-CoV-2 is an RNA virus, its genome is relative stable, thanks to a proofreading polymerase. However, in a situation with extensive viral transmission globally, the evolution of SARS-CoV-2 is not unexpected. When mutations give an advantage in viral replication, transmissibility, or immune evasion, the mutant will eventually become a predominant virus and replace the original virus.
