Coronavirus Variant Found in India is Renamed Delta

Coronavirus Variant Discovered in India is Renamed Delta

If you haven't mastered the name of the newest variant of coronavirus to put nations at risk – B.1.617.2 as evolutionary biologists call it – fear not: the World Health Organization has proposed a solution.

The group said Monday that it had developed a less technical and easier to pronounce system for naming variants – the mutated versions of the virus that have sparked new attacks around the world.

Variants are assigned to letters of the Greek alphabet in the order in which they are given by the W.H.O. identified as a potential threat.

B.1.617.2, which contributed to a fatal surge in India, was named Delta after the new system. This variant can spread even faster than B.1.1.7, the variant discovered in the UK that has contributed to devastating waves of cases around the world. (The new name of B.1.1.7 is Alpha.)

Scientists will continue to assign long sequences of letters and numbers to new variants for their own purposes, but they hope that Greek letters will be easier to roll out of the tongues of non-scientists.

There is also a deeper motivation: The letter and number system was so complicated that many people referred to variants in the places where they were discovered (for example, "the Indian variant" for B.1.617.2). Scientists fear these informal nicknames can be both inaccurate and stigmatizing, penalizing countries for investing in the genome sequencing necessary to sound the alarm of new mutations that may have surfaced elsewhere.

Whether the Greek letters stick is another question. It's been months since experts from the W.H.O. began to discuss the subject, allowing labels such as "the British variant" and "the South African variant" to spread in the news media.

The experts said they considered a number of alternatives, such as taking syllables from existing words to form new words. But too many of those syllable combinations are already recognizable names of places or companies, they said.

And the Greek letters had just been relieved of another task: the World Meteorological Organization announced in March that it would no longer use them to name hurricanes.
