FLiRT variant: The ever-evolving COVID-19 virus

The SARS-CoV-2 virus has undergone many mutations since the pandemic began, creating new strains. Natural selection gives rise to these variations as the virus adjusts to its surroundings and hosts. Because of its increased transmissibility, the virus may benefit from some modifications, such as enhanced transmissibility or resistance to antibody neutralisation.
