Omicron FAQ: 8 key things to know about the new COVID variant today
The CDC director expects cases in the US to rise, as the COVID omicron variant has now been confirmed in 16 states. Stay on top of the latest guidance here.

The omicron variant of COVID-19 has now been confirmed in at least 16 US states and is «likely to rise,» Dr. Rochelle Walensky,director of the Centers for Disease Control and Prevention, said on Sunday on This Week. Although the delta variant of COVID makes up 99.9% of US cases, Walensky said, omicron is spreading quickly. A leading European health agency predicts omicron could become the dominant COVID strain in months (more below.)
There have been more than 5.2 million reported deaths worldwide due to COVID-19.
In the US, President Joe Biden is doubling down on urging vaccines and booster shots until more information becomes available. Experts caution it could be two or three weeks before we know exactly how contagious omicron is and if it can cause more severe illness than other mutations of the virus.
So far, the COVID-19 vaccines have proved to be highly effective in preventing hospitalization and death, with people who are unvaccinated being more than 10 times more likely to be hospitalized if infected. Vaccine-makers are optimistic the current vaccines authorized for use in the US will provide a degree of protection against omicron, too.
Here are eight important things to know about omicron today. For more on COVID boosters, here’s a trick to easily get an appointment and free ride. Here’s how you’ll soon get a COVID test kit for free and details on mixing and matching vaccines.
Omicron could become the dominant COVID variant in Europe in months
Omicron could become the most common COVID variant in months, according to the European Centre for Disease Prevention and Control.
«Mathematical modelling [sic] indicates that the Omicron VOC is expected to cause over half of all SARS-CoV-2 infections in the EU/EEA within the next few months» due to early understandings of the omicron variant’s high transmissibility between people, the center said in a Dec. 2 brief.
Scientists studying the omicron variant in South Africa, where it was first reported to the World Health Organization, have said it’s spreading more than twice as fast as the delta variant. But what isn’t yet known is the spread is hastened because the mutations make it easier to spread among people, if vaccines are less effective against this strain or for some other reason. The study cited by the New York Times has not yet been published or peer-reviewed.
Omicron is already confirmed in 16 US states
First, it was Minnesota, then California and now Hawaii, New York and points in between. The US and other countries were already bracing for an increased caseload as colder weather and holiday revelry drove more people indoors together. Now, concerns over a winter surge of the dominant delta variant join concerns about omicron’s spread.
Omicron has similarities to the delta variant’s mutation
COVID latches onto cells using a spike protein in its structure. Omicron has more mutations than the delta variant, which is considered at least twice as contagious as previous strains. While it isn’t clear yet if omicron is more or less contagious than delta, the presence of those mutations is one cause of concern.
That may be one reason countries around the world have banned travel from some countries in southern Africa and increased travel restrictions that include a negative COVID test 24 hours before travel, regardless of vaccination status.
It isn’t clear how current vaccines will respond to omicron
Scientists are testing whether omicron could cause breakthrough infections in people who are fully vaccinated and reinfections for those who have antibodies from a prior COVID-19 infection. It may take two to three weeks before enough test data reveals how effective the Johnson & Johnson, Moderna and Pfizer vaccines are in protecting against the omicron mutation. Scientists are hopeful, however, that the current vaccines will continue to protect against the new variant.
«We think it’s likely that people will have substantial protection against severe disease caused by omicron,» said Ugur Sahin, co-founder of BioNTech, said uring an interview with Reuters on Tuesday. BioNTech worked with Pfizer to create one of the vaccines authorized in the US.
Still, the fact that omicron has rapidly mutated and spread has rung at least one alarm bell.
«The emergence of the highly mutated omicron variant underlines just how perilous and precarious our situation is,» Dr. Tedros Adhanom Ghebreyesus, leader of the World Health Organization, said on Nov. 29.
Most PCR tests to identify the presence of COVID-19 in the body are free (COVID tests for international travel are the main exception). So it’s good news that the existing nasal swab test has been found to detect the omicron variant — a blood test or other procedure so far is unnecessary.
«Fortunately for us, the PCRs that we mostly use would pick up this very unusual variant that has a real large constellation of mutations,» Dr. Anthony Fauci, the president’s chief medical advisor, said in a Nov. 29 press briefing.

Moderna, Pfizer and Johnson & Johnson are evaluating Plan B
Moderna: Moderna’s Chief Medical Officer Paul Burton told the BBC his company has hundreds of people examining the effectiveness of its current vaccine and booster with the variant. Moderna is also testing a COVID-19 vaccine that could protect against several mutated strains of the coronavirus looking at an omicron-specific booster vaccine. Burton said if Moderna needs to make a new vaccine modified for the variant, it could be available early in 2022.
Pfizer: A Pfizer spokesperson said the company is «constantly conducting surveillance efforts focused on monitoring for emerging variants that potentially escape protection from our vaccine.»
The spokesperson said Pfizer could develop and produce a tailor-made vaccine against that variant in approximately 100 days.
Johnson & Johnson: Johnson & Johnson said it’s working with scientists in South Africa and around the world to evaluate the effectiveness of its COVID-19 vaccine against the omicron variant and has begun work on a new vaccine designed for omicron, if needed.
Booster shots and vaccines are urged to help prevent omicron’s spread
On Thursday, Biden announced a plan to help protect the US against the omicron variant this winter. It includes, among other things:
- Outreach programs to contact people eligible to receive booster shots.
- Making at-home COVID tests «free» for everyone.
- Tighter travel restrictions that require a negative COVID test 24 hours before departure.
- Paid time off for federal workers to get booster shots.
- Securing antiviral pills as a treatment for people who become infected with COVID-19 (these are recommended but not yet FDA approved).
- Sending 200 million more doses of COVID vaccine to international countries in the next 100 days (280 million have already been sent).
Omicron is pronounced these ways
The World Health Organization assigns Greek letters to key COVID variants to help the public easily remember and pronounce the different mutations of the virus. When first announced, search interest in the Greek letters «omicron» and «omega» climbed as people looked for information on the new variant. So far we’ve heard the new omicron variant pronounced by global health leaders as OH-me-cron, OH-mih-cron and OH-my-cron (some of this boils down to ancient Greek).

Bishop Takes Rook: You’ll Be Able to Learn Chess on Duolingo Soon
The course is in beta now but will be available to everyone in a few months.

«Hola, ajedrez» means «Hello, chess» in Spanish. You’ve always been able to learn Spanish on Duolingo. And you’ll be able to learn and practice chess on the language learning app soon. Duolingo announced on April 22 that beta testers can practice the centuries-old board game in Duolingo now, and others will be able to learn the game on the app in a few months.
Chess will be the first new Duolingo course since the app began offering math and music lessons in 2023. And Duolingo hopes that to bring the classic board game to more people of all experience levels.
Duolingo chess lessons aim to be friendly to beginners
I spoke with a Duolingo rep about the upcoming lessons. He said the company wants to continue expanding what people can learn through the app, and chess was an early contender.
Chess is «one of those things that … any age group can learn … but then also something that takes the 10,000-hour theory to really master,» Edwin Bodge, a senior product manager with Duolingo, said. «We thought it would fit with the Duolingo medium really well.»
When I asked why people would use Duolingo over other chess learning sites and tools, Bodge said a lot of other chess content is geared toward advanced users, not newcomers. «We really saw a great opportunity to try and cater to more of a beginner, medium (player) and try and increase access to the game,» he said.
The chess lessons are slightly different from others you might find on Duolingo, like Spanish and math, but the progression system is similar. And from what Duolingo showed me, the lessons really do start at square one, or A1 on a chessboard.
Chess lessons feel similar to other Duolingo lessons
When you start, Duolingo asks how much you already know about chess, like in other lessons on the app. Duolingo will then adjust the lessons according to your response. If you say you’re brand-new to chess and have no knowledge of the game, early lessons will focus on how each piece moves before moving on to capturing other pieces and checking the king. Other lessons are similar to mini-puzzles where you might be asked to capture different pieces using a single piece, like your knight or rook, in four moves or fewer.
You can access hints for each lesson, but if you get something wrong, your opponent will react to show you you’ve left a piece open for capture, like in a real match. And if you keep getting something incorrect, Duolingo will show you what to do. «If you get it wrong multiple times, eventually we’ll show you an arrow that shows you exactly where to move,» Sammi Siegel, a software engineer with Duolingo, said.
If you are subscribed to Duolingo Max and make a mistake in a language lesson, the app can explain the mistake — and what the right solution is — with a feature called Explain My Answer. However, that feature won’t be available with the chess lessons for now. It’s not always easy to explain why something is right or wrong in chess because there are so many millions of different moves.
«We want to get better at fuller explanations,» Siegel said. «There is some mix of AI and model training that we’re hoping to use to better explain why a certain move is wrong.» Because there are so many moves in chess, it’s possible to make moves that could be correct but aren’t the best options. In such instances, Duolingo will show a banner that lets you know that a move isn’t wrong but isn’t necessarily the best move.
Duolingo also said each section represents a range on the Elo rating system, the method by which a chess player’s skills are calculated. As you progress, your lessons will be tougher and more challenging. This is similar to the CEFR language proficiency levels attached to the different language sections in the app.
You’ll also have the opportunity to have «mini-matches» or full-on games against Duolingo’s chess coach, Oscar. These matches will scale in difficulty to challenge you as well, so you aren’t facing a grandmaster-level chess player after your first week of playing the game. But that doesn’t mean you can slack off and play sloppily. If you make a mistake, like leaving your queen open to capture, Oscar will take advantage and leave you scrambling to recover.
While playing against Oscar is good practice, you won’t be able to face off against other players when these chess lessons launch. But Duolingo said matches against other people are something they are looking into, so you might be able to play against a friend over the app in the future. «One of the big reasons why we’re doing this is we think we can get a whole generation of people interested in chess,» Bodge said.
Duolingo’s new chess lessons are now available in the beta version now and will start rolling out on iOS in English in May. Duolingo said it is working to bring these lessons to Android devices and more languages in the coming months.
