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.

FCC Takes Next Step Toward Banning DJI Drones in the US

An FCC vote signals that a retroactive ban on some DJI products may be coming, but that doesn’t mean you’ll have to give up your DJI drone.

If a DJI drone has been on your wish list, you might want to get one while you still can. A vote last week by the FCC could mean that future products from drone maker DJI (and products made with some of its technology) would be banned from import and sale in the US.

The FCC voted 3-0 to «close loopholes in the FCC’s Covered List and secure America’s communication networks against devices determined to pose an unacceptable risk to national security.» In plain English, the vote opens the door to future and retroactive bans of products that use communication technology — such as DJI’s drone radio frequency technology — from import and sale in the US, in the same way it’s already banned Huawei products.

The US government has deemed DJI, based in China, a security risk. It’s also considering a separate ban on TP-Link routers.

The vote isn’t the end of the road, however. Future bans would need to target specific products and would require a period of public consultation. But it appears the groundwork is being set for the FCC to block sales of future and some existing DJI drones from US shores, as well as products that use DJI technology.

The government has called for a DJI audit by the end of the year, but if that doesn’t happen, DJI drone products could be banned for sale by default under a national security law.

DJI asks for a security audit before any ban

A representative for DJI told CNET that while the FCC vote references a rule change that doesn’t currently apply to DJI specifically, the National Defense Authorization Act deadline in December would put Chinese companies like it on the FCC’s ban list, «without any evidence of wrongdoing or the right to appeal.»

Adam Welsh, head of global policy at DJI, said the company has repeatedly said it would be open to audit, but that «more than 10 months have now passed with no sign that the process has begun.»

«The US government has every right to strengthen national security measures, but this must go hand in hand with due process, fairness, and transparency,» Welsh said.

Welsh said DJI is urging the government to start the audit process or grant an extension.

Will DJI drone owners need to give them up?

Because the ban would apply to new sales, not drones that have already been sold, a DJI drone you already own would still be legal to use — at least under current rules.

Government agencies, however, are prohibited from purchasing or using drones from Chinese companies, including DJI.

DJI’s drones consistently rank high in their product category. In January, they dominated CNET’s list of best drones for 2025. But some of the company’s newest products, such as the DJI Mavic 4 Pro, haven’t been available for sale in the United States.

Even DJI products that are not yet banned may be hard to find. The website UAV Coach has posted a guide to the bans and reports that, due to inventory issues, most DJI drone models are sold out at retailers regardless of future FCC action.

November Nights Dazzle with Three Meteor Showers. How to Watch Like a Pro

You’ll need to get away from urban and suburban lights, but you won’t need binoculars or a telescope.

Skygazers, get ready for an active November. Following Tuesday’s supermoon, this month we’ve also got three annual meteor showers: the Northern Taurids, the Southern Taurids and the Leonids. Northern Taurids started on Oct. 20, and Southern Taurids — one of the longest meteor showers of the year — began on Sept. 20. The Leonids are expected to start Thursday, on Nov. 6.

Even though two of these meteor showers are already in progress, the best parts of each are still to come. And while these showers aren’t as prolific as the biggest ones, including August’s Perseids and January’s Quadrantids, you can still marvel at meteors with a bit of luck and some tips we’ll provide.

Not everyone understands what a meteor shower actually is, but it’s fairly simple. Shooting stars are a common occurrence in space around planet Earth. According to NASA, 48.5 tons of meteoritic material hit Earth’s atmosphere every year. Sometimes, enough of that material comes from the same spot, and we humans refer to those as meteor showers.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

Southern Taurids: The longest one

The Southern Taurids shower lasts for two months, making it one of the longest meteor showers of the year.

Southern Taurids peaked on the evening of Nov. 4 into Nov. 5, spawning upwards of five meteors per hour during that peak. Southern Taurids is known for its increased chance of fireballs, which are meteors that are brighter than most. According to some reports, these fireballs can be brighter than the planet Venus when they streak across the night sky.

All meteor showers are named for the constellations where they appear to originate, a spot known as the radiant. For the Southern Taurids, the radiant is in the Taurus constellation near the Pleiades star cluster, so that is where you’ll want to look for them. Taurus will be visible in the eastern sky shortly after sunset and end its evening in the western sky as the sun rises.

Northern Taurids: Peaks later than its sibling

The Northern Taurids meteor shower is set to peak next week, on Nov. 11 and 12. It’s identical to the Southern Taurids, only with a later peak date. The origin point will be the Taurus constellation, producing an average of five meteors per hour with an increased chance of fireballs.

The Leonids: The most active

Of the three November meteor showers, Leonids should be the most active. It is fed by the Tempel-Tuttle Comet, which can produce some dense debris clouds, resulting in very strong showers. The Leonids meteor shower is set to peak on Nov. 16-17.

Some sources say that seeing as many as 15 visible meteors per hour is possible, while NASA estimates a more conservative three per hour under dark skies. It’s impossible to know for sure how active this shower will be until the peak occurs.

As the name implies, Leonids will appear out of the Leo constellation. Leo is visible in the eastern sky between midnight and 1 a.m. local time.

According to the American Meteor Society, Leonids has produced some intense meteor showers as recently as 2002, but isn’t scheduled to do so again until 2031, 2064 and 2099 as the comet returns to the solar system. During these rare meteor storms, NASA says that it’s possible to see upwards of 1,000 meteors per hour.

Tips for watching meteor showers

Here are some tips and tricks that will help increase your odds of spotting a meteor in November.

Get away from light pollution

This is the most important guideline to follow. Simply put, city lights make meteors harder to see.

«Light pollution will definitely hamper your viewing of meteors,» Michelle Nichols, director of public observing at the Adler Planetarium in Chicago, told CNET. «The more light pollution you are under, the fewer meteors you’ll see.»

Nichols says that unfavorable conditions can reduce the number of meteors you see by upwards of 75%.

Head to the countryside and find a spot that is as dark as possible. (There are other sources of light pollution that humans can’t do anything about, like the moon.)

The Southern Taurids peaks during November’s full moon, which is also a supermoon, meaning it shares the maximum amount of light pollution you can get from the moon. If you’re going to skip any of these showers, the Southern Taurids is probably the best choice. The other two showers will have much more favorable celestial conditions.

Don’t take any equipment

Meteor showers typically have an origin point, but you won’t need binoculars or telescopes.

«You want to just use your eyes,» said Nichols. «Binoculars or telescopes both look at ever-smaller pieces of sky, and you want to be able to look around at the entire sky.»

Meteors are very fast, and a magnification device may obstruct your ability to see the whole path. Nichols says that Taurids meteors tend to travel at 17 to 18 miles per second while Orionids may travel as fast as 41 miles per second.

Also, meteors don’t last for a long time.

«Look for short-lived, quick streaks of light,» Nichols says. «Meteors tend to last a fraction of a second to maybe a few seconds for the longer-lived ones.»

Nichols also notes that much of the material falling to Earth’s surface is «only about the size of a grain of sand.» As such, the streak humans often see isn’t the meteor itself, but rather the «glowing, superheated air that surrounds that bit of comet material» as it plummets toward Earth.

Dress for the occasion

Unless you live in the Deep South, it’s likely to be cold outside in November. Dressing for the occasion means you’ll be able to stay out longer, even if it’s chilly.

«When you go outside, dress warmly in layers, even if it’s not terribly cold where you are,» says Nichols. «You’ll be out there for a while, and at night, you may easily get chilled, especially if it’s damp out.»

Nichols recommends bringing an extra chair to put your feet on to keep them off the cold ground, especially if it’s wet, and also recommends against drinking alcohol, which causes blood vessels to dilate, causing the body to lose heat faster.

Patience is a virtue

The phrase «it’s a marathon, not a sprint» is about as apropos as it gets for meteor watching. Showers are unpredictable, and every number you’ve seen in this article or elsewhere online is essentially an estimate. You’ll want to make sure to give yourself as much time as you can to get settled.

«Give your eyes at least 20-30 minutes to adjust to the darkness,» Nichols advises. «You may not see meteors right away. And when you do, they’ll be sporadic.»

If it were easy to spot meteors, then it wouldn’t be special. You can help yourself by reducing your phone screen brightness to its lowest setting to preserve your night vision, and by using flashlights, not big camping lanterns.

You Probably Have a Better Password Than The Louvre Did: Learn From Its Mistake

Following the infamous jewel heist, reports show the museum’s security and password habits were atrocious.

Is your password easily guessable? Is it, oh, I don’t know, maybe the name of the world-famous Paris museum you’re trying to protect?

The brazen theft of more than $100 million in jewels from the world-famous Louvre on Oct. 19 captured the world’s attention, for obvious reasons. As of Wednesday, French police have arrested seven suspects, but the jewels have not yet been recovered. Now reports show the Louvre has had security issues in the past, including one that wouldn’t pass the most basic cybersecurity test: The museum’s name itself, Louvre, may have been one of its passwords.

The French newspaper Libération reports that the French cybersecurity agency ANSSI audited the Louvre’s security in 2014 and 2015. The museum failed badly.

One part of the audit described unguarded rooftop access. That’s somewhat relevant today, since thieves reportedly used a truck-mounted electric ladder to reach a balcony and cut through window glass. Not quite the roof, but apparently equally unguarded.

The audit also said the museum’s security software at the time was running on Windows Server 2003, which was set to lose support from Microsoft at that time, more than a decade ago.

The Louvre’s password was once ‘Louvre’

One of the most significant flaws in the Louvre’s cybersecurity was lazy password use. «Louvre» appeared to be the password to access the museum’s video surveillance. One computer login password was «Thales,» the name of the software developer, which we’re guessing was visible on the login screen.

A representative for the Louvre didn’t immediately respond to a request for comment.

While Libération’s investigation indicated that many of the same problems remain, we don’t know which issues the Louvre staff corrected in the decade since the audit. Perhaps the Louvre’s current password is L0uvr31500$$ now or something even tougher to guess. M0n@ L1$@, maybe?

Now is an excellent time to update your own passwords

If the Louvre report wasn’t enough incentive, it’s essential to give your own passwords a check ahead of the holidays, when many people increase their online shopping time.

CNET’s latest survey shows that nearly half of Americans engage in risky password habits. US adults don’t shy away from using personal information as a part of their passwords. Fifteen percent include birthdays or anniversaries, 14% include a pet’s name and 11% use part of the user’s own name or a family member’s name.

You can improve passwords with a few simple steps, or use a password manager that can generate strong passwords and keep them organized. When creating passwords, keep a few essential points in mind.

Don’t use your name or any identifying information as part of your password.
Use passwords that include upper and lowercase letters, numbers and symbols.
Update your passwords if you become aware of a data breach affecting services you use.
Don’t leave any unencrypted notes revealing your password lying around.

Remember, today’s passwords aren’t just on your phone and computer, but also on potentially vulnerable devices like Wi-Fi routers, security systems and more.
