Our COVID Vocabulary Wants a Reset

Top-of-the-line and hardest components of being a science author is performing as a sort of jargon liaison. Bizarre, obscure, aggressively multisyllabic phrases seem in scientific discourse; I, wielding nothing however a Google Doc, a cellphone, and the Powers of the Web™, wrest these phrases from their educational hidey-holes and attempt to pin them down with some endearing but correct analogy. If I do my job properly, generally readers by no means even must see the unique phrase, as a result of there’s a extra approachable technique to describe it.

In numerous instances, that’s how these phrases transfer—from educational to journalist to reader. (Hello there.) However generally the phrases leapfrog me. And that’s after I panic.

I’ve panicked loads on this manner in the course of the pandemic. The coronavirus has prompted an enormous shift within the methods we speak with each other, and about each other. That’s what folks do in a disaster: We borrow, therapeutic massage, and invent phrases to make sense of what’s taking place round us.

However this most up-to-date go-round has concerned numerous linguistic “leakage,” the linguist Elena Semino advised me final month. “Swiftly, one thing for an expert neighborhood is getting used for everybody.” We’ve needed to assimilate a complete slew of phrases from public well being, immunology, and medication, a few of them completely overseas (cytokines, optimistic predictive worth, R-naught), others extra acquainted however with colloquial and educational meanings that at the least partially battle (bubbles, breakthroughs, boosters). The transition doesn’t all the time go easily, and confusion and misunderstandings, very similar to contagion, are very arduous to rein in as soon as they’ve began to unfold.

By now numerous our pandemic verbiage has been misconstrued. Final week, I requested specialists, mates, household, and colleagues what field-hopping phrases or phrases had been inflicting the most important complications this previous yr; the suggestions got here pouring in. What follows is certainly not complete, and possibly represents a futile train in refining and redefining: The horses have left the barn, the ships have sailed from the harbor, the phrases have already slipped by way of my fingers like a lot semantic sand. However I suppose I’ll proceed to know at them, till they’ve escaped me totally.


Let’s begin with asymptomatic, which scientists use to indicate infections that by no means make folks really feel sick. Appears easy sufficient. However many who begin off their an infection symptomless won’t keep that manner, and till somebody is rid of the coronavirus, it’s inconceivable to say whether or not they’re asymptomatic or presymptomatic. The boundary between no signs and signs can be surprisingly fuzzy. COVID-19 signs range enormously from individual to individual, and are considerably subjective: A headache two days after a optimistic coronavirus check might be a COVID symptom or an ill-timed hangover.

Really silent instances, although, are detectable solely by way of a check that hunts for bits of the coronavirus. These infections don’t rely as COVID-19, a time period that’s supposed to be reserved for a documentable, symptomatic illness that unspools from a subset of SARS-CoV-2 infections. The virus, SARS-CoV-2, is what truly infects us, what truly transmits, what exams truly detect. Not COVID. (I’m screaming right into a void right here, however that additionally means there’s no such factor as a COVID check, and there’s no such factor as asymptomatic COVID.)

Okay, high quality. Say you do check optimistic for SARS-CoV-2, and also you lose your sense of odor, and your nostril is sort of operating a bit—you may have straight-up symptomatic COVID. Perhaps the individual you mingled with unmasked a couple of nights in the past does too, however they’ve obtained chills, nausea, and a excessive fever that can wreck them for weeks. Shock! Each of you may have delicate COVID-19, a euphemistic time period that’s nonetheless generally used to explain all instances too “inconsequential” to land somebody within the hospital. (At that time, a case is “extreme.”) Delicate is likely to be helpful for accumulating population-level knowledge, however numerous specialists dislike the adjective as a result of it elides the debilitating and generally very prolonged diseases that may unfurl from a SARS-CoV-2 an infection, together with lengthy COVID. From the start, it’s been clear that “there’s delicate, average, and extreme, even for outpatients,” Sri Edupuganti, an infectious-disease doctor and vaccinologist at Emory College, advised me.

Whichever route the pendulum swings, for the primary few days after your signs begin, you’re going to be in … quarantine, proper? Sadly, no. Two years into our run with COVID, that’s still one of the terms we most commonly mess up. Appropriately used, quarantine describes the time frame when individuals who suppose they’ve been uncovered to SARS-CoV-2 are purported to cloister themselves—a precaution in case an an infection manifests. If you realize you’re contaminated, due to, say, a optimistic check or legit COVID signs, you’re going into full-blown isolation. (Until you’re in the UK, the place they apparently play it fairly quick and free with these phrases and “use them interchangeably,” Saskia Popescu, an infection-prevention professional at George Mason College, advised me. Woof.)

To confuse issues additional, now we have additionally adopted quarantine as a catchall moniker for considerably sheltered pandemic life, or lockdown-lite. (Simply examine Google for 8 trillion listicles on quarantine cats, quarantine TV reveals, quarantine meals, quarantine quarantinis …) A part of this obsession might be cultural baggage​​: If People heard quarantine earlier than the pandemic, it was often in foreboding contexts—outbreak-centric historical past texts, or the plot twists of Contagion-esque sci-fi thrillers. (We’ve, in spite of everything, been utilizing the time period for hundreds of years, since at the least the time when ships arriving from plague-stricken international locations have been cordoned off for 40 days earlier than docking—therefore the quar- prefix.) Isolation is a way more well-worn time period, one thing we’ve all gotten at the least a style of; it lacks that only-in-crisis attract. Quarantine—quarantine!—sounds manner worse.


We’ve struggled with cheerier phrases, too. The prospect of being absolutely vaccinated, for example, is fairly interesting. Our COVID photographs considerably scale back the chance of getting contaminated or critically sick with SARS-CoV-2, and slash the probabilities that the virus might be handed on to others.

However oh boy, is absolutely vaccinated additionally a nightmare to outline. For starters, being absolutely dosed isn’t the identical as being absolutely immunized, as a result of it takes a few weeks for immune cells to study the contents of a shot and react. (Even the professionals use this one in a complicated manner: The CDC counts folks as absolutely vaccinated the day they obtain their second dose of Moderna’s or Pfizer’s vaccine or their first of Johnson & Johnson’s, however says they aren’t “thought-about” absolutely vaccinated till two weeks after that.) The rise of third doses and booster photographs has additionally made the idea of full vaccination fairly a bit squishier. If these further photographs are supposed to construct iteratively on prior defenses, does that take us to … fuller vaccination? Tremendous vaccination? Or did we in some unspecified time in the future get much less full? (For now, at the least, you don’t want a 3rd dose or a booster to be thought-about absolutely vaccinated.) Totally additionally implies completeness, even invulnerability, when no vaccine in existence can ever confer such a factor.

That vaccines aren’t impenetrable shields towards an infection isn’t dangerous information; it’s very a lot in step with how immunity works, waxing or waning as encounters with microbes or vaccines construct it up or as time or pathogen evolution erode it away. This has been some extent of confusion when discussing vaccine effectiveness, the formal time period for a way we measure a shot’s success; these numbers will all the time range, relying on what we’re measuring effectiveness towards. (This one, to be truthful, isn’t extensively misused a lot as extensively misunderstood.) Establishing any an infection in any respect is the best feat for a virus to perform—step one towards inflicting illness—and the toughest occasion for a vaccinated immune system to dam. That’s all the time the place safety will falter first.

That appears like a bummer, however SARS-CoV-2 infections among the many vaccinated are totally anticipated—particularly as a result of our photographs have been designed to assist us stamp out illness, not eradicate all optimistic check outcomes. It’s unlucky, then, that we’ve spent months wringing our palms over breakthroughs of all severities. The time period breakthrough has a longtime historical past in vaccinology—counting up these occasions is important to understand how properly inoculations are working out and in of trials. However due to our fuzzy understanding of vaccine effectiveness, the phrase’s use in pandemic occasions has develop into rather more doom and gloom, with some studies even equating breakthroughs with vaccine failures. That’s completely not the case.

Think about the CDC’s definition for a SARS-CoV-2 breakthrough: any test-based detection of the virus in somebody who’s been absolutely vaccinated towards the coronavirus. This dumps an unlimited vary of postinoculation outcomes into the identical class, the whole lot from exceedingly uncommon hospitalizations and deaths to completely silent infections that might’ve gone unnoticed if not for that choicely timed check. Merely receiving a optimistic check outcome doesn’t assure that an individual will expertise illness or unfold the virus to another person. For these causes, numerous specialists have sworn off utilizing the time period breakthrough—and wince noticeably when it comes up in dialog. (Many choose post-vaccination an infection.)

If the terminology of breakthroughs has been exaggerated towards the unfavourable, the discourse round pure immunity is likely to be its overhyped foil. Pure immunity is one other foster-phrase; lengthy earlier than the pandemic began, scientists used it to explain the safety left behind after an an infection by a bona fide pathogen. However within the age of COVID, the phrase has develop into weaponized right into a false binary: If infection-induced immunity is pure, some have argued, immunity obtained by way of totally different means have to be unnatural—synthetic, undesirable, a harmful hoax, and even, in some instances, an ethical failure, the religious-studies professional Alan Levinovitz lately defined in The Washington Submit.

However that dichotomy is scientifically nonexistent. Inoculations are designed to imitate the microbes that trigger infections, and sometimes find yourself tickling fairly related responses out of immune cells. The primary distinction is that vaccines ship their defensive classes safely, with out risking illness. As a nod to this, the immunologist John Wherry and others choose utilizing phrases similar to infection-acquired and vaccine-acquired immunity. They’ve even began utilizing one other phrase—hybrid immunity—to consult with the heightened safety that’s afforded when folks with a previous SARS-CoV-2 an infection get vaccinated.

If the concern really is that vaccines are a technological unknown, there’s at the least one different manner to take a look at this. Vaccines, like many different human innovations, are body-inspired. They leverage and construct on our inborn defenses, in a lot the identical manner that glasses can improve imaginative and prescient and good trainers can velocity up an individual’s tempo. They’re not an indictment of the immune system and its quite a few powers, however a tribute to them. In a pandemic, vaccines, in defending each the individuals who obtain them and the folks these recipients work together with, actually do accomplish what no different instrument can—and that, if something, is price saying over and time and again.
