In October 2020, SARS-CoV-2 lineage B.1.617 emerged in India, causing an exponential increase in COVID-19 cases across the country. The lineage is further divided into three subgroups: B.1.617.1, B.1.617.2, and B.1.617.3, of which the B.1.617.2 variant (also known as Delta variant) has been designated as Variant of Concern (VOC) by WHO because of significantly increased infectivity. The mutations L452R and E484Q, along with P681R in the furin cleavage site are reported to lead to increased ACE

SARS-CoV-2 Lambda (C.37) variant was first detected in Peru in December 2020 and has been designated as a VOI by the WHO in June 2021, due to a heightened presence of this variant in Peru, Chile, United States of America, Argentina, etc.The spike protein of the Lambda variant is more infectious, which is attributed to the T76I and L452Q mutations. Another mutation F490S has already been associated with reduced susceptibility to antibodies generated in patients who had recovered from COVID. Thi

On Nov. 24, 2021, the variant B.1.1.529 was first identified in South Africa, and only two days later, WHO announced that B.1.1.529 constitutes a variant of concern, named Omicron. There are more than 30 mutation sites on the S gene of variant B.1.1.529. Omicron has a greater binding affinity than the original SARS-CoV-2 virus, with levels more comparable to what we see with the Delta variant. Some of the mutations have been detected in previous variants, such as Alpha and Delta, and have been
