XBB.1.5 and the Coronavirus-Naming Free-for-All

7 min read

These days, it’s a actual headache to maintain tabs on the coronavirus’s at any time-shifting subvariants. BA.2, BA.4, and BA.5, 3 Omicron permutations that rose to prominence previous 12 months, ended up complicated plenty of. Now, in addition to people, we have to deal with BQ.1.1, BF.7, B.5.2.6, and XBB.1.5, the variation of Omicron presently showcasing in concerned headlines. Recently, things have also gotten considerably stranger. Along with the strings of letters and figures, numerous nicknames for these subvariants have begun to achieve traction on-line. Where as soon as we had Alpha and Delta and Omicron, we now have Basilisk, Minotaur, and Hippogryph. Some people today have been referring to XBB.1.5 basically as “the Kraken.” A listing compiled on Twitter reads much less like an stock of variants than like the directory of a mythological zoo.

The nicknames are not official. They ended up coined not by the Earth Wellness Group but by an informal group of scientists on Twitter who feel Omicron’s numerous rotating versions are worthy of additional widespread discussion. The names have, to an extent, caught on: Kraken has already built its way from Twitter to a quantity of major news web pages, like Bloomberg and The New York Occasions. Unofficial epithets have come and gone all through the pandemic—remember “stealth Omicron” and the “Frankenstein variant”?—but these new ones are on an additional amount of weirdness. And not everyone’s a admirer.

The names affiliated with the coronavirus have been a fraught discussion given that the pandemic’s earliest days, as researchers and community-well being figures have tried to use terms that are comprehensible and maintain people’s focus but that also stay away from pitfalls of inaccuracy, concern-mongering, or xenophobia and racism (see: Donald Trump referring to the coronavirus as “the Chinese virus” and “kung flu”). The official names for variants and subvariants—names such as SARS-CoV-2 B.1.1.7—come from the Pango naming method, which was fashioned by evolutionary biologists in the early months of the pandemic to standardize variant-naming techniques. As baffling as they can feel, they comply with a crystal clear logic: Below the system, B refers to a certain COVID lineage, B.1 refers to the sublineage of B lineage, B.1.1 refers to the initially sublineage of the B.1 sublineage, and so on. When the names get as well long, a letter replaces a string of numbers—B.1.1.529.1, for illustration, will become BA.1.

These official names do not precisely roll off the tongue or stick in the memory, which turned a difficulty when new variants of concern commenced to crop up and the entire world started groping for methods to speak about them. In May well 2021, the WHO instituted its now-acquainted Greek-letter naming program to stamp out the geographic associations that ended up getting prominence at the time. B.1.1.7, B.1.351, and B.1.617—which have been being referred to respectively as the U.K. variant, the South African variant, and the Indian variant—became Alpha, Beta, and Delta. But then, alas, came Omicron. Instead than providing way to nevertheless one more new Greek-letter variant, Omicron has used additional than a calendar year branching into sublineages, and sublineages of sublineages. As a final result, the nomenclature has devolved back again into alphanumeric incomprehensibility. 7 unique Omicron sublineages now account for at the very least 2 % of all infections, and none accounts for a lot more than about 40 p.c (although XBB.1.5 is threatening to overwhelm its rivals).

It’s great news that the strategies in which the coronavirus has been mutating a short while ago haven’t been considerable enough to create a entire new, widespread, and perhaps significantly extra worrisome model of by itself that the entire world has to contend with. But it also tends to make conversing about the virus much much more annoying. Enter T. Ryan Gregory, an evolutionary biologist at Canada’s College of Guelph who is 1 of the leaders of a small, informal group of experts that have taken it upon on their own to name the quite a few subvariants that the WHO does not deem worthy of a new Greek letter. The names—Hydra, Cerberus, Centaurus—originated on Twitter, the place Gregory compiled them into a list.

Their benefit, Gregory informed me, is that they fill the space in between the Greek and Pango programs, permitting people today to go over the lots of latest Omicron variants that do not justify a new Greek letter but are however, perhaps, of curiosity. You can believe of it in the same way we do animal taxonomy, he said. Contacting a variant Omicron, like calling an animal a mammal, is not significantly descriptive. Contacting a variant by its Pango title, like contacting an animal by its Latinate species designation, is hugely descriptive but a little bit unwieldy in common parlance. When we speak of farm animals that moo and produce milk, we talk not of mammals or of Bos taurus but of cows. And so BA.2.3.20 grew to become Basilisk.

To choose irrespective of whether a new lineage justifies its personal title, Gregory advised me, he and his colleagues look at both equally evolutionary elements (how various is this lineage from its predecessors, and how about are its mutations?) and epidemiological components (how considerably havoc is this lineage wreaking in the population?). They’re hoping to make the process much more formal, but Gregory would choose that the WHO just take around and standardize the process.

That, nevertheless, is not likely to materialize. When I requested about this, Tarik Jasarevic, a WHO spokesperson, told me that the business is informed of the unofficial names but that, for the minute, they’re not necessary. “Virologists and other scientists are monitoring these variants, but the general public does not need to distinguish amongst these Omicron subvariants in get to much better realize their chance or the actions they need to get to shield themselves,” he mentioned. The WHO’s posture, in other terms, is that the differences among 1 Omicron subvariant and a further merely haven’t mattered substantially in any functional feeling, because they shouldn’t have any result on our habits. No make any difference the sublineage, vaccines and boosters nonetheless offer you the most effective security offered. Masks nevertheless work. Advice on tests and isolation, way too, is the similar across the board. “If there is a new variant that calls for community conversation and discourse,” Jasarevic advised me, “it would be specified a new variant of concern and assigned a new label.”

The WHO isn’t by yourself in objecting. For Stephen Goldstein, an evolutionary virologist at the University of Utah, the new names are not just unwanted but potentially destructive. “It’s completely insane that we’re possessing random folks on Twitter name variants,” he informed me. For Goldstein, dressing up each and every new subvariant with an ominous monster title overplays the dissimilarities concerning the mutations and feeds into the panic that arrives every single time the coronavirus shifts type. In this see, distinguishing one particular Omicron sublineage from a different is fewer like distinguishing a wolf from a cow and a lot more like distinguishing a white-footed mouse from a deer mouse: critical to a rodentologist but not seriously to any person else. To go as significantly as naming lineages right after terrifying legendary beasts, he claimed, “seems certainly supposed to scare the shit out of men and women … It really is really hard to understand what broader objective there is below other than this really self-serving clout chasing.”

Gregory explained to me that panic and interest are not his group’s goal. He also stated, although, that his group is considering of switching from mythological creatures to a thing far more neutral, these kinds of as constellations, in element to handle problems of whipping up avoidable stress. When it arrives to XBB.1.5, some of that panic undoubtedly currently exists, whipped up by less-than-nuanced headlines and Twitter personalities who feast on moments like these. Irrespective of whether or not the identify Kraken has contributed, the concern is that XBB.1.5 may be a variant so immune-evasive that it infects absolutely everyone all about all over again or so virulent that it amps up the risk of any presented an infection. So considerably, that does not feel to be the case.

As my colleague Katherine Wu noted in November, we are probable (although by no suggests undoubtedly) stuck for the foreseeable upcoming in this Omicron purgatory, with its much more gradual, more piecemeal sample of viral evolution. This is undoubtedly preferable to the sudden and sudden emergence of a perilous, considerably distinct variant. But it does necessarily mean that we’re possible going to be arguing about no matter if and how and with what names to explore Omicron subvariants for some time to appear.

Whichever facet you appear down on, the condition of variant-naming fairly well encapsulates the condition of the pandemic as a total. Rarely just about anything about the pandemic has been a matter of universal arrangement, but the current nomenclatural no cost-for-all looks to have taken us someplace even additional splintered, even more anarchic. We’re not just arguing about the pandemic we’re arguing about how to argue about the pandemic. And there is no close in sight.
