Three new variants of Covid-19 have been detected in recent weeks, leading to increased vigilance across the world as officials say a variant found in the United Kingdom could be up to 70 percent more transmissible.
However, none of the variants so far has been found to be more fatal, or more likely to be able to evade vaccines or treatments.
A new variant was first reported in the United Kingdom on December 14. Named VUI-202012/01 (the first Variant Under Investigation in December 2020), it is thought to have first appeared in mid-September.
Referred to by some experts as the B117 lineage, this has rapidly become the dominant strain in cases of Covid-19 in many parts of the UK.
