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.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration

European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.

BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.

The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.

Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.

However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.

Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.

European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge

Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.

Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.

Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.

The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.

Mortgage rates track the 10-year Treasury yield

Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.

In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.

Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.

If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.

But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.

There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.

That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.

Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.

CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.

“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.

AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.

GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.

Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.

In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.

And that’s leaving aside the deep animosity between the parties.

The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.

For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network

Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.

Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.

Kyiv has leveled accusations against SpaceX

Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.

Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.

Here’s an overview of Starshield and its distinctions from Starlink.

What is Starshield and how does it function?

Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.

SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.

In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.

SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.

On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.

How does Starshield contrast with Starlink?

While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.

Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.

Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.

SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
