Geneva: The B.1.617.1 and B.1.617.2 variants of COVID-19, first identified in India, have been named as ‘Kappa’ and ‘Delta’ respectively, the World Health Organisation (WHO) announced on Monday as it named various variants of the coronavirus using Greek alphabets.
“Today, @WHO announces new, easy-to-say labels for #SARSCoV2 Variants of Concern (VOCs) & Interest (VOIs). They will not replace existing scientific names, but are aimed to help in public discussion of VOI/VOC,” Dr Maria Van Kerkhove, WHO’s technical COVID-19 lead, tweeted on Monday.
The UN health agency named the B.1.617.1 variant of the COVID-19 as ‘Kappa’ while the B1.617.2 variant was dubbed ‘Delta’. Both the variants were first found in India.
The WHO’s move came nearly three weeks after India objected to the B.1.617 mutant of the novel coronavirus being termed an “Indian Variant” in media reports with the Union health ministry, pointing out that the UN’s top health organ has not used the word “Indian” for this strain in its document.
On May 12, the ministry dismissed that “without any basis and unfounded” media reports that have used the term “Indian variant” for the B.1.617 mutant strain, which the WHO recently said was a “variant of global concern”.
“Several media reports have covered the news of the WHO classifying B.1.617 as a variant of global concern. Some of these reports have termed the B.1.617 variant of the coronavirus as an ‘Indian Variant’,” the ministry said in a statement in New Delhi.
“These media reports are without any basis, and unfounded,” it said.

In a statement, the UN health agency said on Monday that an expert group convened by the WHO has recommended labeling using letters of the Greek Alphabet, i.e., Alpha, Beta, Gamma, which will be easier and more practical to discuss by non-scientific audiences.
“The established nomenclature systems for naming and tracking SARS-CoV-2 genetic lineages by GISAID, Nextstrain and Pango are currently in use and will remain so with scientists and in scientific research,” it added.
It said the WHO and its international networks of experts are monitoring changes to the virus.
“If significant mutations are identified, we can inform countries and the public about any changes needed in reaction to the variant and prevent its spread, it added.
Globally, systems have been established and are being strengthened to detect signals of potential variants of concern (VOC) and interest (VOI) and assess these based on the risk posed to global public health.
National authorities may choose to designate other variants of local interest/concern, it added.
