Comments The World Health Organiaation said on Tuesday, 1 June, that only one strain of the COVID-19 variant, which was first found in India, is being now considered "of concern", news agency AFP reported. Scientifically nomenclatured as B.1.617, the variant of the coronavirus is considered as the cause for the massive second wave of the COVID-19 pandemic in the country. The B.1.617 variant has also been labelled as the “triple mutant variant” as it has three different lineages. The WHO, however, in its latest announcement, has said that only the second of the three strains – B.1.617.2 – is now deemed to be of concern, while the other two descendants of the variant have been dropped from such consideration.
