It is yet another offshoot of the globally-dominant Omicron Covid variant.Omicron has outperformed the earlier Alpha, Beta, Gamma and Delta coronavirus variants since emerging in late 2021. Scientists have said a new Covid variant that carries an "extremely high number" of mutations may drive further waves of disease by evading the body's defences. In the beginning of the pandemic, they said mutated versions of . . We will know more in the coming weeks about how well the rapid at-home tests perform to detect the new variant. Any COVID variant can cause long COVID symptoms but so far, we're seeing less long COVID with the Omicron variant and subvariants than with previous variants, like Delta.
