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.

For the most up-to-date news and information about the coronavirus pandemic, visit the WHO and CDC websites.

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.

COVID PCR tests can identify the omicron variant

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).

Google’s AI Mode Is Getting New Agentic Features for Restaurant Reservations and More

AI Mode can now do most of the work to find dinner reservations for you.

Google’s AI Mode is getting new agentic capabilities and expanding to 180 new countries and territories around the world, Google announced Thursday. AI Mode allows you to ask questions directly to Google and it’ll kick off a series of searches on your behalf. From there, it will surface relevant information to your query without the need to do any of the deep research yourself. It changes the way you search for things online, and it’s getting even smarter with this latest rollout.

Powered by DeepMind’s Project Mariner, the latest additions bring us further into the agentic AI future we’ve been promised for some time, directly from a search box. Instead of just finding things for you, AI Mode can now do things for you, like finding dinner reservations, flights or concert tickets. The update also brings personalized recommendations and link-sharing capabilities for easier collaboration with friends and family.

Most of the new features are either limited to premium AI subscribers and tucked behind an experiment in Google Labs, but it might not take long before they’re a standard part of your future search experience.

Google did not immediately respond to CNET’s request for further comment.

Restaurant recommendations

Instead of searching for restaurant reservations and then clicking on a specific website to make a reservation, AI Mode surfaces everything you need to complete the action right there. Since it’s contextually aware, you can add specificities to your query that a typical Google search wouldn’t handle well.

You can add the type of cuisine, number of people, time and location to a single query, and AI Mode will get to work and display real-time restaurant reservation time slots to choose from.

Google says it’s partnered with OpenTable, Resy, Tock, Ticketmaster and several other companies to make finding and doing what you want easier, since you won’t have to put in the legwork yourself.

This feature is currently rolling out to Google AI Ultra subscribers in the US who have enabled the specific experiment in Labs.

Personalized recommendations

Another experiment that’s currently available in the US (that also needs to be enabled in Labs) is personalized recommendations. Google says it’s starting with dining-related recommendations, which implies more options will be on the way in the future.

The experiment will use your past conversations with AI Mode, places you’ve interacted with on Search and Maps to provide suggestions tailored specifically to you.

Share AI Mode links with others for collaboration

If you’re planning a vacation or a party, you can now share your research directly with others with a new link-sharing feature built into AI Mode. People who interact with the link will be sent to the last response sent by AI Mode and can continue the conversation on their own to do more exploration on the topic. The original sender of the links can manage them and delete them at any time.

IPhone or Android, Here’s How to Finally Escape That Endless Group Chat

Done with a group chat? Here’s how to ghost it on any service.

One reason people prefer group chats in Apple’s iMessage or RCS texting is the extra control and security these platforms provide. If everyone in your group is using iPhones, or if you’re on Android chatting through RCS, you’ll get features like typing indicators, high-quality media sharing, and the option to mute or leave a conversation when you need fewer notifications.

The biggest advantage is privacy. Both iMessage and RCS group chats offer end-to-end encryption, so your conversations stay secure. The only time that doesn’t apply is when a thread includes a mix of iPhone and Android users, which limits encryption support.

Knowing these differences can help you manage your chats more effectively, whether you’re keeping up with friends, planning events, or just looking for a little more control over your notifications.

And with RCS support with iOS 18, group chats that include a mix of iPhone and Android participants have more features than ever — but it’s not at the level you’ll experience when a conversation is fully on iMessage or Google Messages. «Green bubble chats» from an iPhone to an Android phone can now include typing indicators, higher-quality media and easier group chats.

However, RCS conversations between the iPhone and Android phones don’t include encryption now, but it should be added in a future update. This will hopefully give these conversations a similar level of privacy that we expect when using chat services like iMessage, WhatsApp or Signal.

Regardless of how you’re in a group chat with others, you can leave a chat. Here are the steps to leave any conversation from your phone’s texting app, regardless of whether it’s happening on iMessage, RCS or as a mixed MMS chat.

Leaving group chats on an iPhone

You can leave group conversations on your iPhone in two ways. You can either mute a chat,which keeps you in a conversation but you no longer receive notifications about it, or you can outright leave and no longer have access to the chat.

On an iPhone, open Messages and go to the chat thread you want to leave. At the top of the screen are conversation controls, a group of icons with the participants. Tap this to open a pop-up menu. As long as your conversation has four or more participants, iOS gives you the ability to tap Leave this Conversation with red text. If your chat has three or fewer participants, though, the option is grayed out, but you can tap Hide Alerts to prevent the conversation from notifying you further. Tapping Hide Alerts also allows you to mute a conversation, letting you keep access to a chat without necessarily leaving it. These steps apply to both iMessage conversations and to those over RCS.

Hide and block MMS chats on an iPhone

Although you can’t officially leave MMS group chats, you can hide or block the conversation. It’s not as good as outright leaving a conversation (other participants will still see you as in it), but you at least have no personal evidence of the conversation continuing.

On an iPhone, visit the group chat and tap the conversation controls. Instead of seeing Leave this conversation, you will see the option to Delete and Block this conversation. If you’d rather just mute the conversation instead of deleting and blocking it, you can hit Hide Alerts to mute it.

Leave group chats on an Android phone

On an Android phone using Google Messages, visit the chat thread you want to leave. Tap the conversation’s name to bring up the Group Details menu. Within this menu is the Leave Group button. Unlike with iMessage, you can leave chats with as few as three participants.

If you want to just mute notifications, tap Notifications on the Group Details screen to bring up a window with notifications controls. This includes options to make the conversation stay Silent to prevent it from ringing your chat, and if you tap Lock Screen, a pop-up menu will give you the option to prevent notifications. Tap Don’t show notifications at all to enable.

Hide and block MMS chats on an Android phone

On an Android phone with Google Messages, follow the same steps to access options for controlling notifications. This includes visiting the MMS chat thread and then tapping either the name of the conversation or the names of the participants at the top to bring up the Group Details menu. You won’t see a Leave Group option like you did with an RCS thread, but you do get the same ability to tap Notifications to access controls for hiding the conversation. This includes the same options for turning the conversation to Silent and to select Don’t show notifications at all.

SMS vs. MMS vs. RCS

SMS stands for Short Message Service and debuted in 1992. Text messages are limited to 160 characters. MMS stands for Multimedia Messaging Service and supports sending photos, videos or other files and messages longer than 160 characters. MMS supports a group of people chatting in a single conversation thread, while SMS can text multiple people at once but is sent as individual messages to each person. RCS, which launched 15 years ago, is short for Rich Communication Services and can show typing indicators, read receipts and has end-to-end encryption.

While cross-platform chat apps like WhatsApp, Signal and Telegram have better controls for conversations, encryption and privacy, regardless of the type of phone participants are using, they don’t support SMS, MMS or RCS. That’s why the default messaging app on most phones is still widely used, even if it means that a group chat is on a less feature-filled, unsecured standard like MMS.
