CDC and WHO recommend fully vaccinated should wear masks indoors. Here’s the latest

The CDC recently updated its stance to say fully vaccinated people should wear masks in certain areas. We’ll explain what’s going on.

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

The Centers for Disease Control and Prevention is recommending fully vaccinated people wear masks indoors again in some areas — including schools — it announced during a telebriefing Tuesday. This is different from its guidance earlier in July that said it’s safe for teachers and students who are fully vaccinated to skip the face masks. So why the sudden change? A spike in COVID-19 cases across the US caused by the highly contagious delta variant has resulted in the CDC updating its guidance for mask wearing.

The World Health Organization continues to recommend that to slow the rapidly spreading delta variant, everyone should continue to wear face masks in crowded areas, even people who are past the two-week mark after receiving their second vaccine dose, for example from Pfizer, Moderna or AstraZeneca.

Both the WHO and CDC agree that people who aren’t vaccinated should continue to wear face masks. But given the high rate of protection that vaccinated people have against the delta variant and other COVID strains, why are some medical experts in conflict about a barrier over your nose and mouth? We continue to update this story.

CDC guidance: Fully vaccinated should continue wearing masks in some areas

The CDC on Tuesday changed its guidance for mask wearing to say that vaccinated people should continue wearing masks indoors in certain areas of the country. This includes areas where COVID-19 cases are on the rise. It also changed the guidance for K-12 schools, saying everyone should wear a mask, regardless of vaccination status. Earlier this month, it said fully vaccinated teachers and students don’t need to wear masks inside the school.

Originally, the guidelines said those who are fully vaccinated can «resume activities without wearing masks or physically distancing» except where required, such as in planes and businesses. CDC Director Dr. Rochelle Walensky previously stuck to that guidance on NBC’s Today show on June 30, saying fully vaccinated people are protected from the delta variant.

The CDC warned CNN that there’s still a small chance fully vaccinated people can become infected with the new variant if they’re exposed. We’ve asked the CDC for comment.

What is the CDC’s new guidance for kids and teachers?

Those who aren’t vaccinated — ages 2 and up — need to wear a mask while inside but don’t have to when they’re outside. For fully vaccinated teachers and students, the CDC recommends continuing to wear masks inside the school building.

For child care programs, regarding schools with children younger than 12, universal mask use can be implemented, as children this age aren’t eligible for the COVID-19 vaccines yet. Mask mandates can also go into effect if coronavirus transmission is high in that community.

For schools that can’t provide adequate physical distancing, the CDC says «layered COVID-19 prevention strategies» should be put in place to protect kids and teachers who aren’t fully vaccinated.

Why are experts at odds over masks for vaccinated people?

In June, WHO officials repeated a longstanding recommendation that everyone should wear masks to stem the spread of the virus. Meanwhile, the CDC until Tuesday had been continuing to uphold its guidance that not all fully vaccinated Americans need to wear masks indoors or maintain social distancing. White House Chief Medical Adviser Dr. Anthony Fauci said that those who’ve had two doses of the vaccine should still «go the extra step» of wearing a mask when traveling to places with low vaccination rates.

A few days after the WHO recommended that people who have received the COVID-19 vaccine should continue wearing a face mask, Fauci explained why the advice differed from the CDC’s. «There’s a reason for that,» he said in a virtual White House press briefing. «The WHO is responsible for the planet as a whole. It’s different in the world in general from here in the United States.»

So, while the WHO is monitoring the pandemic around the world, with a majority of people unvaccinated, the CDC is responding to the situation in the US, where the vaccines have been shown to work quite effectively against hospitalization from the delta variant. Only 13.9% of the global population is fully vaccinated, according to vaccine tracker site Our World in Data. The US nearly quadruples that number: 49.7% of Americans are considered fully vaccinated as of July 4, according to the Mayo Clinic.

For Fauci and the CDC, the focus is on getting a greater number of Americans vaccinated in the first place. On July 4, Fauci said that 99.2% of COVID-related deaths last month involved unvaccinated people.

What is WHO’s position on mask wearing?

Wearing a mask consistently continues to be important, even for people who are vaccinated, a WHO official said during a press briefing in late June. «People cannot feel safe just because they had the two doses. They still need to protect themselves.»

Wearing masks in public places is essential to keep people from inhaling particles that will cause them to become sick, Dr. Maria Van Kerkhove, an American infectious disease epidemiologist, said during the same briefing.

While the Pfizer and Moderna vaccines are showing robust protection against variants, «breakthrough» infections may still sporadically occur. In a case in early June, a fully vaccinated woman in Napa, California, died from COVID-19. She was over 65 and was reported to have underlying medical conditions.

Why is the coronavirus delta variant serious?

The delta variant is the latest of new coronavirus variants and is the most contagious of the variants identified so far, according to the WHO. The delta variant has been identified in 96 countries so far and is spreading among the unvaccinated population, the organization said during the press conference.

«The delta variant is currently the greatest threat in the US to our attempt to eliminate COVID-19,» Fauci said during a White House press briefing on June 22.

Will there be new mask mandates or tighter restrictions?

Some countries have already begun tightening COVID-19 restrictions. For instance, four cities across Australia have returned to lockdown, including Sydney’s state of New South Wales. In the US, Los Angeles County is strongly recommending face masks indoors, regardless of whether someone has been vaccinated, though masks aren’t required in most places. Some countries within Africa and Asia — for instance, South Africa and Malaysia — have also moved into lockdown due to the delta variant spreading.

Some places never loosened mask mandates, such as airports and airlines. In the US, other public transportation facilities require masks, such as buses and trains.

Samsung’s Wild-Looking Tri-Fold Phone Debuts at APEC Summit in South Korea

The Galaxy phonemaker showed off a twin-hinged foldable at a Korean consumer tech show.

Samsung unveiled its first triple-display foldable phone for consumers at a tech exhibition hall during the APEC CEO Summit in South Korea. The Korean publication Dailian reported that the new phone will launch in November or December.

The tri-fold phone, which doesn’t have an official name yet, was revealed as a prototype on display. Whereas the Galaxy Z Fold 7 and Galaxy Z Flip 7 fold in half along one hinge, Samsung’s next device folds in two places to be as compact as a typical smartphone with a 6.5-inch outer screen, then unfolds for a tablet-size 10-inch screen, according to The Chosun Daily. Compare that with dual-screen foldables that have inner screens measuring approximately 8 inches. The Z Fold 7 has a single crease on its main screen; the new tri-fold could have two creases.

Samsung has been at the forefront of foldable phones since releasing the first Galaxy Fold in 2019 and the Galaxy Z Flip in 2020. At the time, it faced fierce competition from Motorola and Huawei — the latter of which gained a significant lead in 2024 with its own tri-fold Huawei Mate XT, which was followed by a second version. Samsung’s launch of its own competitor keeps the company in the game.

Here’s your first look at the Samsung Galaxy Z TriFold.

These two consumer tri-folds have their differences. The Huawei Mate XT’s two hinges fold in opposite directions like an accordion, giving it a Z shape, while Samsung’s device has two screens that fold inward in what Dailian (through Google Translate) asserts is «G-shaped.» Given that Samsung has branded its foldable line as the Z-series, it’s ironic that the company didn’t adopt that shape and format for its tri-fold.

Samsung didn’t release any more details about its tri-fold, though Dailian expects it to be even pricier than the Galaxy Z Fold 7, which starts at $2,000in the US. From photos of the device — apparently a prototype — behind glass, you can see a front-facing camera on the inner display (when unfolded) and outer screen (when folded up). But since Samsung also didn’t show the device folding, there are a lot of questions about its durability and capability before its supposed launch in a month or two.

It’s not a total surprise to see Samsung’s tri-fold ready to go. For years, the company has displayed various flexible display designs, including three-screen formats, during CES. In the last few months, there’s been a steady flow of rumors and outright executive confirmations that Samsung was gearing up to unveil its tri-fold. Now we’ll have to see whether the company that’s fought so hard to be at the forefront of smartphone design can release another format that dominates the folding phone niche — all before one of its biggest rivals, Apple, even releases its first foldable.

Samsung didn’t respond to a request for comment.

Be Wary of AI Videos as Hurricane Melissa Hits Jamaica. How to Spot a Fake

AI-generated storm videos are spreading rapidly online. Here’s where to find reliable information.

As Category 5 Hurricane Melissa bears down on Jamaica with winds topping 180 mph, social media is being hit by a surge of AI-generated and misleading videos, showing catastrophic flooding, collapsing buildings and rescue scenes that never happened.

Across X, TikTok, Instagram, WhatsApp and other social media platforms, fake clips spread quickly, racking up millions of views in hours. Many of these videos are spliced footage from past storms or clips created entirely with text-to-video AI tools.

In times of crisis, like a dangerous and imminent natural disaster, these fake videos can create confusion, panic and distraction at a time when accuracy can be life-saving.

Natural disasters have always bred rumors and recycled footage, but the rise of AI-generated video has supercharged the problem. Tools like OpenAI’s Sora and other AI-video platforms can render realistic-looking images of storms, floods and damage scenes in seconds, reaching millions online in just a few hours.

Why storms are a magnet for fake news

Storms are visual, emotional and fast-moving, which is the perfect recipe for viral misinformation. In years past, videos were often taken out of context or labeled as a different storm. Now, they can be digitally fabricated from scratch.

Some depict apocalyptic flooding that hasn’t occurred, while others claim to show «real-time» conditions hours before landfall. Several videos that have circled this week include images of sharks swimming in the storm surge and unsettling depictions of human suffering.

False videos like these can exaggerate the danger of the storm, create panic, undermine trust and distract emergency responders, as misinformation pulls attention from verified reports.

The following three videos are all fake. They are labeled (albeit briefly) with the Sora watermark, which indicates they were made in OpenAI’s video generator.

How to separate truth from fiction online

When social feeds fill with dramatic hurricane clips, it’s important to separate truth from fiction.

«You have to be very discerning,» Senator Dana Morris Dixon, Jamaica’s information minister, said. «You have to know what is good information from bad information. If you want to know where the storm is going, if you want to know what to do, you need to look for official sources.»

Dixon highlighted that the Jamaica Information Service, Office of Disaster Preparedness and Emergency Management’s information sites and the Office of the Prime Minister page are resources for legitimate, timely updates.

Here are some ways to be discerning.

Check the source. If the video comes from an unfamiliar account, lacks a timestamp or carries no recognizable media branding, assume it is fake until verified. Also, look for the Sora watermark indicating it was made in OpenAI’s app, or read the comments to see if someone else has flagged the video as fake.

Ask yourself if it’s new and local. Does the geography match Jamaica? Is the footage recent? Many «Melissa» clips could actually be from past Caribbean or Gulf storms.

Cross-check before believing. Confirm through trusted outlets, like the Meteorological Service of Jamaica and the US National Hurricane Center, or established media like the BBC, Reuters or the Associated Press.

Pause before sharing. A viral video can cause harm if it spreads misinformation. Wait until a credible source verifies it before reposting.

Go local. If you’re in the affected area, rely on local emergency agencies, radio stations and city or county-level officials for evacuation and safety updates.

Monitor official alerts. For real-time instructions, stick with government channels and local emergency feeds. Your safety depends on accurate information, not viral content.

As AI-generated media becomes easier to produce, hurricanes like Melissa offer a preview of a new reality: one in which you can’t trust much of the information you see online.

Staying safe means being skeptical and diligent when looking for accurate and even lifesaving news.
