The Department of Justice (DOJ) is appealing a Florida judge’s Monday decision to strike down the mask requirement for public transportation. Federal judge Kathryn Mizelle ruled the Centers for Disease Control and Prevention (CDC) exceeded its authority under the Public Health Service Act of 1944. Meanwhile, giddy passengers and flight crew have been discarding their face coverings as airlines, the Transportation Safety Administration, several local transit authorities, Uber and Lyft, all removed their mask requirements.
The Gist: Despite DOJ’s appeal, which appears to be aimed at preserving its own authority to act during health crises, rather than reinstating the current mask requirement (which was set to expire in two weeks anyway), the tone of the Biden administration is clearly shifting. Earlier this week President Biden told reporters that the decision to wear a mask is “up to them,” meaning individual Americans.
In the bumpy transition out of the emergency phase of the pandemic, we now have a patchwork of rules for masking. This is even true within healthcare facilities: some, including Houston Methodist and Iowa-based UnityPoint Health, are no longer requiring masks for visitors or employees who are not involved in patient care.
With COVID cases now rising in 41 states as mask mandates fall, the next month will prove critical in determining whether “endemic” COVID remains manageable, or once again stresses the healthcare system and other critical infrastructure.
But officials caution that people should not presume they have protection against the virus going forward.
Before omicron, one-third of Americans had been infected with the coronavirus, but by the end of February, that rate had climbed to nearly 60 percent — including about 75 percent of kids and 60 percent of people age 18 to 49, according to federal health data released Tuesday.
The data from blood tests offers the first evidence that over half the U.S. population, or 189 million people have been infected at least once since the pandemic began — double the number reflected in official case counts. Officials cautioned, however, that the data, in a report from the Centers for Disease Control and Prevention, does not indicate people have protection against the virus going forward, especially against increasingly transmissible variants.
“We continue to recommend that everyone be up to date on their vaccinations, get your primary series and booster, when eligible,” CDC Director Rochelle Walensky said during a media briefing.
Kristie Clarke, the CDC official who authored the report, said by February, “evidence of previous COVID-19 infections substantially increased among every age group, likely reflecting the increase in cases we noted as omicron surged in this country.”
Clarke said the greatest increases took place in those with the lowest levels of vaccination, noting that older adults were more likely to be fully vaccinated.
The largest increases were in children and teenagers through age 17 — about 75 percent of them had been infected by February, based on blood samples that look at antibodies developed in response to a coronavirus infection but not in response to vaccination. That’s about 58 million children.
The blood test data suggests 189 million Americans had covid-19 by end of February, well over double the 80 million cases shown by The Washington Post case tracker, which is based on state data of confirmed infections. Clarke said that’s because the blood tests captures asymptomatic cases and others that were never confirmed on coronavirus tests.
With the omicron surge, officials had expected there would be more infections. “But I didn’t expect the increase to be quite this much,” Clarke added.
Separately, CDC is about to publish another study that estimates three infections for every reported case, she said.
A subvariant of omicron known as BA.2 is now the dominant strain in the United States, according to new data from the Centers for Disease Control and Prevention (CDC).
The variant has been steadily rising in proportion because of its increased transmissibility compared to the original omicron strain, and it represented 54.9 percent of new cases for the week ending March 26, according to CDC data. That is up from about 27 percent two weeks earlier.
The BA.2 subvariant is thought to be about 30 percent more transmissible than the original BA.1 omicron strain, which itself was already more contagious than earlier versions of the virus.
Importantly, though, experts say there is no evidence that BA.2 causes more severe disease than the original omicron strain or that it evades the protection from vaccines to a greater degree.
The subvariant may cause some increase in cases after weeks of steady declines that have led to a relative lull in the virus. But it is unclear how sharp the increase will be, and people who are vaccinated and boosted are still well-protected against severe disease.
The Food and Drug Administration on Tuesday authorized a fourth COVID-19 vaccine shot for people 50 and older, which could further help protect the most vulnerable from the subvariant.
“CDC says the BA.2 subvariant of Omicron is now dominant in the US,” tweeted Leana Wen, a public health professor at George Washington University. “Reminder that while this appears to be even more contagious than the original Omicron, it is not more virulent than previous strains, and existing vaccines still protect well against severe disease.”
CDC Director Rochelle Walensky said last week that her agency was monitoring the subvariant, particularly in the Northeast, where it has been concentrated so far.
“Over the past week, we have seen a small increase in reported COVID-19 cases in New York state and New York City, and some increases in people in the hospital with COVID-19 in New England, specifically where the BA.2 variant has been reaching levels above 50 percent,” she said.
“This small increase in cases in the Northeast is something that we are closely watching as we look for any indication of an increase in severe disease from COVID-19 and track whether it represents any strain on our hospitals. We have not yet seen this so far.”

Nearly a year ago, President Biden announced that the United States would be the “arsenal of vaccines for the world,” just as America served as an arsenal for democracies during World War II. With the president’s leadership and the consistent bipartisan support of Congress, the United States has delivered more than half a billion coronavirus vaccines to 114 lower-income countries free of charge, a historic accomplishment. This example spurred contributions from other wealthy nations and contributed to vaccination of almost 60 percent of the world.
But the global battle against covid-19 is not done. Instead, the challenge has changed. The lowest-income countries, where vaccinations have reached less than 15 percent of people, are now declining free vaccine supply because they don’t have the capacity to get shots in arms fast enough.
We must therefore not just provide an arsenal; to protect our allies against future variants, we must also provide the support they need to ramp up their vaccination campaigns. That effort requires money, and despite generously funding our covid-19 response up to this point, Congress is now failing to provide the resources we need.
I am writing to say: This bodes serious trouble for the world.
Despite a period of relative calm here at home, we’re again seeing cases and hospitalizations spike in Europe and Asia, even in places with higher levels of vaccination than the United States. These surges are due to the more-transmissible BA.2 subvariant of the already highly infectious omicron strain. Without additional funding, we risk not having the tools we need — vaccines, treatments, tests, masks and more — to manage future surges at home. And no less troubling, if we don’t close the vaccine gap between richer and poorer countries, we will give the virus more chances to mutate into a new variant.
Since the virus first emerged, the package of tools we’ve developed to fight it has proved resilient against all coronavirus variants. But there’s no guarantee that will remain true. A new variant that evades our defenses might once again fuel new surges of severe illness and batter the global economy. Helping all countries protect their populations by supercharging vaccination campaigns is our best hope to prevent future strains from emerging and ending this pandemic once and for all.
Turning vaccines into actual vaccinations has been difficult even in wealthy countries, where capable health systems, state-of-the-art cold chains and public awareness campaigns mean that anyone who wants a vaccine can get one. In countries without strong health infrastructure — without enough freezers and refrigerated trucks to keep vaccines from spoiling or enough health-care workers to reach rural populations living miles from the nearest health facility — it’s much tougher. We’ve also seen the same vaccine myths and disinformation that swirl through our media ecosystem spread just as rapidly through social media and hurt public trust abroad.
But we’ve also learned how to successfully tackle these challenges. In December, the Biden administration launched an initiative called Global VAX to help low-income countries train health workers, strengthen health infrastructure and raise vaccine access and awareness. While vaccine coverage in those countries remains far below the global average, the rapid progress we’ve supported in places such as Ivory Coast, Uganda and Zambia show what is possible when governments that are committed to fighting covid-19 have the global support they need.
Without more funding, we would have to halt our plans to expand the Global VAX initiative. The United States would have to turn its back on countries that need urgent help to boost their vaccination rates. And many countries that finally have the vaccines they need to protect their populations would risk seeing them spoil on the tarmac.
We can’t let this happen. It not only endangers people abroad but also risks the health and prosperity of all Americans. The virus is not waiting on Congress to negotiate; it is infecting people and mutating as we speak.
Over the past two years, both parties in Congress have repeatedly stepped up to fight covid-19 in an inspiring show of bipartisan unity. Now, we need our leaders to come together once more. With an effective strategy in place and the tools to transform covid-19 from a killer pandemic to a manageable respiratory disease, the United States has the expertise and capabilities the world needs to win the fight against this virus. We need Congress to let us take the fight to the front lines.
Starting next month, the federal government will stop reimbursing hospitals and other providers for the vaccination, testing, and treatment of uninsured COVID-19 patients. So far, about 50K providers have submitted a total of $20B of claims for COVID-related care for the uninsured.
Congress has yet to authorize more funding for this and other COVID relief programs, after stripping $15.6B from the latest government spending package. Though the White House is asking Congress to authorize $22.5B for further COVID aid and surge preparedness, it’s not clear how much of any new funding would go toward reimbursing care for the uninsured.
The Gist: This news comes as US officials expect a rise in cases driven by the Omicron BA.2 subvariant. Hospitals, already struggling with high labor and supply expenses, will face further margin pressures if a future COVID surge brings increased hospitalizations.
This will be especially true for safety net hospitals, and for those in states which haven’t expanded Medicaid. At the same time, 15M Americans are also at risk of losing Medicaid coverage when the federal government ends the public health emergency. Lower-income patients and the hospitals that treat them have already shouldered COVID’s worst effects, and the funding stalemate risks further worsening their situation.
The expected green light for a second coronavirus booster shot poses a challenge to the Biden administration, which will need to work overtime to convince a public that has largely decided to move on from the COVID-19 pandemic.
Both Pfizer and Moderna have filed for emergency use authorization with the Food and Drug Administration for a fourth dose of their respective vaccines, citing evidence that protection from the third shot has decreased enough to warrant a fourth dose.
Yet the nation’s vaccination and booster rates have dropped to record lows, just as experts and officials are bracing for the possibility of another wave of infections from the BA.2 subvariant of omicron.
The BA.2 version of omicron is much more transmissible than the original variant. Combined with relaxed precautions like indoor masking and waning immunity among those who have not received a vaccine booster, cases have risen sharply in Europe in the past few weeks, and the U.S. could follow shortly.
The omicron subvariant is responsible for about 35 percent of all cases in the country. In some regions though, like the northeast, it is responsible for the majority of infections.
Federal health officials are reportedly poised to authorize a fourth dose of coronavirus vaccine for adults age 50 and older as soon as this week. A fourth shot is already authorized for the immunocompromised.
But the issues that plagued the administration during the first booster campaign loom large, and officials are likely eager to avoid the same pitfalls.
Chaotic and at times disparate messages from administration health officials culminated in a complicated set of recommendations about who should be getting booster shots, and why, which experts said helped depress enthusiasm.
“I think that some of the low uptake of boosters, especially amongst people who would benefit, the high risk population, is because that message has been diluted,” said Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health Security.
But the underlying disagreement about the goal of booster shots has not changed. While there’s widespread agreement that older Americans are much more at risk for severe outcomes, it’s still not clear if younger people will benefit from an additional dose.
Much of the debate has centered on whether the goal is to prevent people from being hospitalized with COVID-19 or whether the goal is to prevent them from getting sick at all, even if it is milder.
Anthony Fauci, White House chief medical advisor and the nation’s top infectious disease doctor, said regulators are trying to determine how low protection against hospitalization needs to drop before a booster is warranted.
“So the real open question that we don’t know definitively the answer to, is how long is the durability of protection against severe disease going to last even when the protection against infection diminishes substantially,” Fauci said during a Washington Post event last week.
“For example, we know that when you get down to a rather low level 30, 40 or so percent of protection against infection, you still have, when you look at hospitalization, a high degree [of protection],” Fauci said.
President Biden last summer promised widespread boosters for all Americans by the end of September, well before the FDA and the Centers for Disease Control and Prevention (CDC) had examined the evidence.
While officials were careful to say the booster program was contingent on the FDA and CDC giving the green light, scientists inside and outside the government argued there wasn’t enough evidence showing protection against severe illness and hospitalization dropped to levels that warranted a booster.
The CDC initially decided against recommending broad authorization, and instead recommended a booster shot for people over the age of 65, as well as anyone who was at “high risk” of exposure to the virus in the workplace.
The agency eventually decided to make everyone eligible, but by then much of the damage had been done. Vaccinated Americans have largely shown they are not interested in getting a booster.
According to current CDC data, less than 45 percent of all adults have received a booster shot, but the number rises to about 67 percent of adults age 65 and older.
Adalja said it makes sense to be proactive and have a plan to get additional booster shots to the older group. But he said the decisions should be left to the scientists, and the health agencies should make decisions independent of the White House.
“Keep the politicians out of it,” Adalja said. “The miscommunications occurred because they made boosters a political issue, not a scientific issue.”
But even if there is a targeted recommendation, a stalled funding request in Congress further complicates matters. The U.S government does not have enough doses on hand to vaccinate everyone who would be eligible for another booster.
The White House says it needs tens of billions of dollars in COVID response funding, which is tied up due to political disagreements. Administration officials say they don’t have enough doses on hand to cover anyone other than the immunocompromised and people aged 65 and older.
But an independent analysis from the Kaiser Family Foundation found the government only has enough vaccine supplies to cover 70 percent of the 65 and older group.
Cases of COVID-19 have increased during the last 14 days in 10 states and Washington, D.C., with the latest additions of the district and Illinois.
Nationwide, COVID-19 cases decreased 15 percent over the past 14 days, according to HHS data collected by The New York Times. But as the more contagious omicron subvariant BA.2 continues to spread, cases are ticking upward in 10 states and D.C. as of March 25. Cases were moving upward in nine states as of March 24, with D.C. and Illinois reporting increases a day later.
Here are the 14-day changes for cases in each state reporting an increase, according to HHS data collected by The New York Times:
New York: 44 percent
Kentucky: 35 percent
Arkansas: 23 percent
Colorado: 21 percent
Connecticut: 18 percent
Texas: 17 percent
Massachusetts: 15 percent
Vermont: 13 percent
Rhode Island: 11 percent
Washington, D.C.: 5 percent
Illinois: 1 percent
The latest variant proportion estimates from the CDC show the omicron subvariant BA.2 accounts for more than one-third of COVID-19 cases nationwide and more than half of cases in the Northeast. Rhode Island has the highest proportion of BA.2 cases of all states, according to the latest ranking of states by the subvariant’s prevalence.
“If we maintain our preparedness, an increase in cases does not need to be a cause for alarm like it once was,” Jeff Zients, White House COVID-19 response coordinator, said in a March 23 media briefing. “We know what tools we need to fight the virus. Unfortunately, because of congressional action, we’re at risk of not having these tools readily available.”
President Joe Biden signed into law March 15 a sweeping $1.5 trillion bill that funds the government through September. The legislation did not include COVID-19 funding the White House had requested from Congress due to partisan disagreement about offsetting the funding.
There is no clear path to approval of more COVID-19 funding.
The lack of funding is affecting resources for COVID-19 testing and treatment. The Health Resources and Services Administration stopped accepting providers’ claims for COVID-19 testing and treatment of the uninsured March 22 due to a lack of sufficient funds. The federal government is also cutting back shipments of monoclonal antibody treatments to states by 30 percent, and the U.S. supply of those treatments could run out as soon as May.
As parents await an approved vaccine for children under 5, Moderna said on Wednesday a study had found its two-dose pediatric vaccine to be safe for young children, toddlers and babies. Its effectiveness, however, was complicated by the spread of the coronavirus’s omicron variant. While the pediatric vaccine generated an immune response equivalent to that of young adults before the highly transmissible variant emerged, those immune defenses were less strong in the face of omicron. In children, the pediatric vaccine was about 40 percent effective, Moderna said. The company plans to submit the data to the Food and Drug Administration for consideration in the coming weeks.
The FDA also faces requests to authorize a second booster vaccine dose for adults. But even if they are authorized, Biden administration officials said they lack the funds to purchase those shots. They said they’ve bought enough doses for Americans age 65 and older, as well as the potential initial regimen for children under 5, but can’t buy more doses for people in other age groups unless Congress passes a delayed $15 billion funding package. It’s not yet clear whether additional doses for adults will be necessary, but officials said placing orders for doses ahead of time has been an important lesson of the pandemic. White House officials have expressed worry that vaccine manufacturers will prioritize orders placed by other countries.
That concern comes as omicron’s BA.2 subvariant of the coronavirus now amounts to as much as 70 percent of new infections in much of the United States, according to the genomic surveillance company Helix. That version of the virus has prompted a surge of cases in Europe and fear that the United States will experience its own wave, similarly to how it has mirrored Europe in the past. A broad increase in cases has so far not happened in the United States, and disease experts don’t know for sure whether it will. If it does, it’s unclear whether the pandemic policies of the Biden administration and private institutions would substantially change.
A program to ensure global vaccine equity was doomed from the beginning to fall short, a Washington Post analysis found. The initiative, called Covax, was meant to convince wealthy and poor countries to combine their money to order vaccine doses in advance and then share them in a way that would protect the most vulnerable people first. But the program’s supporters underestimated the desperation of the wealthier countries, which snatched up doses from manufacturers for their own residents. Covax was also slow to adapt as nations declined to participate. Now, more than one-third of the world has not received a vaccine dose — a result that not only is inequitable, but also makes it easier for new variants to emerge.
In a study published Monday, people who had covid-19 had a 46 percent higher risk of developing Type 2 diabetes or being prescribed medication to control their blood sugar within a year than those who had not had the coronavirus. Greater severity of covid symptoms was associated with a higher chance of developing diabetes, but even people with less severe or asymptomatic infection had an increased risk, according to the study of more than 181,000 Department of Veterans Affairs patients. The study did not prove cause and effect but did show a strong association between covid-19 and diabetes.
Other important news
Omicron’s BA.2 subvariant has become the world’s dominant form of the coronavirus. The Post created a map and several charts to help you visualize how it’s spreading around the world.
White House press secretary Jen Psaki said Tuesday that she had tested positive for the coronavirus a second time. She had been scheduled to travel to Europe with President Biden and other administration officials, but canceled her trip.
A new omicron subvariant of the virus that causes COVID-19, BA.2, is quickly becoming the predominant source of infections amid rising cases around the world. Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another surge in the U.S. and how best to protect yourself.
What is BA.2, and how is it related to omicron?
BA.2 is the latest subvariant of omicron, the dominant strain of the SARS-CoV-2 virus that causes COVID-19. While the origin of BA.2 is still unclear, it has quickly become the dominant strain in many countries, including India, Denmark and South Africa. It is continuing to spread in Europe, Asia and many parts of the world.
The first omicron subvariant, BA.1, is unique in the number of alterations it has compared to the original version of the virus – it has over 30 mutations in the spike protein that helps it enter cells. Spike protein mutations are of high concern to scientists and public health officials because they affect how infectious a particular variant is and whether it is able to escape the protective antibodies that the body produces after vaccination or a prior COVID-19 infection.
BA.2 has eight unique mutations not found in BA.1, and lacks 13 mutations that BA.1 does have. BA.2 does, however, share around 30 mutations with BA.1. Because of its relative genetic similarity, it is considered a subvariant of omicron as opposed to a completely new variant.
While standard PCR tests are still able to detect the BA.2 variant, they might not be able to tell it apart from the delta variant.
Is it more infectious and lethal than other variants?
BA.2 is considered to be more transmissible but not more virulant than BA.1. This means that while BA.2 can spread faster than BA.1, it might not make people sicker.
Does previous infection with BA.1 provide protection against BA.2?
Yes! A recent study suggested that people previously infected with the original BA.1 subvariant have robust protection against BA.2.
Because BA.1 caused widespread infections across the world, it is likely that a significant percentage of the population has protective immunity against BA.2. This is why some scientists predict that BA.2 will be less likely to cause another major wave
However, while the natural immunity gained after COVID-19 infection may provide strong protection against reinfection from earlier variants, it weakens against omicron.
How effective are vaccines against BA.2?
A recent preliminary study that has not yet been peer reviewed of over 1 million individuals in Qatar suggests that two doses of either the Pfizer–BioNTech or Moderna COVID-19 vaccines protect against symptomatic infection from BA.1 and BA.2 for several months before waning to around 10%. A booster shot, however, was able to elevate protection again close to original levels.
Importantly, both vaccines were 70% to 80% effective at preventing hospitalization or death, and this effectiveness increased to over 90% after a booster dose.
How worried does the US need to be about BA.2?
The rise in BA.2 in certain parts of the world is most likely due to a combination of its higher transmissibility, people’s waning immunity and relaxation of COVID-19 restrictions.
CDC data suggests that BA.2 cases are rising steadily, making up 23% of all cases in the U.S. as of early March. Scientists are still debating whether BA.2 will cause another surge in the U.S.
Though there may be an uptick of BA.2 infections in the coming months, protective immunity from vaccination or previous infection provides defense against severe disease. This may make it less likely that BA.2 will cause a significant increase in hospitalization and deaths. The U.S., however, lags behind other countries when it comes to vaccination, and falls even further behind on boosters.
Whether there will be another devastating surge depends on how many people are vaccinated or have been previously infected with BA.1. It’s safer to generate immunity from a vaccine, however, than from getting an infection. Getting vaccinated and boosted and taking precautions like wearing an N95 mask and social distancing are the best ways to protect yourself from BA.2 and other variants.
