Over-the-counter rapid antigen tests for COVID-19 can help slow the spread of the delta variant — here’s when to use them

Making rapid antigen tests for COVID-19 cheaper and more accessible can catch the infectious cases before they spread and help everyone resume normal activities safely.

The rise of the highly transmissible delta variant around the U.S. has increased demand for rapid antigen COVID-19 tests that can be purchased from a pharmacy without a prescription, used at home, school or work and that give results in 15 minutes.

On Sept. 9, 2021, the White House announced several initiatives to improve access to rapid antigen tests: It will use the Defense Production Act to boost the production of tests, require retailers to sell rapid tests at cost, distribute free rapid tests to community health centers and food banks and expand free testing in pharmacies.

Rapid antigen testing makes it much easier to get tested for COVID-19, which helps detect infectious cases before they spread. But many people are still unsure of how best to use these tests and whether they are accurate enough to be useful.

There are several FDA-approved rapid tests on the market including Abbott BinaxNow, Ellume and Quidel QuickVue. These cost as little as $7-12 each and can be used to test adults and children aged 2 and up, regardless of whether they have symptoms.

Rapid antigen tests have a big advantage over lab-based PCR testing in terms of speed and convenience. Getting results in 15 minutes rather than waiting a day or more for PCR test results means it’s possible to identify COVID-19 cases right away and take precautions to prevent transmission. Having rapid testing available over-the-counter means that a lot more people will get tested since the test is easy to perform and far more convenient than PCR testing. So rapid tests can catch a lot more COVID-19 cases overall than relying only on PCR testing.

As a health economist who studies public health policy to combat infectious disease epidemics, I know that making COVID-19 testing accessible, accurate and fast is critical to slowing transmission of the virus and helping everyone resume normal activities safely.

How accurate are rapid antigen tests?

Two types of rapid tests are used for detecting an active COVID-19 infection: rapid antigen tests that detect viral proteins using a paper strip and rapid molecular tests – including PCR – that detect viral genetic material using a medical device.

It’s important to remember that rapid antigen tests serve a different purpose than PCR testing, which is considered the gold standard even though it isn’t 100% accurate. Rapid tests are designed to identify cases with a high enough viral load in the nasal passage to be transmissible – not to diagnose all COVID-19 cases. The Abbott BinaxNOW rapid antigen test may only detect 85% of the positive cases detected by PCR tests. But the key is that published studies found that they detect over 93% of cases that pose a transmission risk, which is what matters most for getting the pandemic under control. Ellume correctly identifies 95% of all positive cases, and Quidel QuickVue accurately identifies 85%. All three tests correctly identify upwards of 97% of all negative cases, regardless of symptoms.

How should rapid tests be used?

Rapid antigen testing can be used in three ways to slow transmission. First, people can perform a rapid test when there is a suspected or known COVID-19 exposure. Second, rapid testing can provide an extra precaution before any activity with a higher risk of transmission, such as gatherings or travel. Third, it’s also possible to test on a regular basis – weekly, for instance, if enough tests are available – to catch cases that otherwise might go undetected.

It’s important to have a plan for what to do based on the test results. If you get a positive result, immediately take precautions to slow transmission such as self-isolating, letting close contacts know about the test result and reporting the case to health authorities. Less than 3% of positive results are false positives, but a second rapid test the following day or a PCR test can provide further confirmation if needed.

If you get a negative result from a rapid test, it means you are currently very unlikely to be infectious. A viral load that is too low to be detected by rapid antigen tests is almost surely too low to be transmissible. But it’s important not to let your guard down completely. The tests don’t detect 100% of infectious cases, so it’s possible for a small number to evade detection or for some cases to become infectious within hours after the test. For this reason, it may be a good idea to maintain other precautions. And, if you have symptoms or a known exposure, it’s a good idea to do a follow-up rapid antigen or PCR test just in case the first test was a false negative.

Think of the rapid antigen test as a snapshot in time: A negative test doesn’t necessarily mean you don’t have COVID-19. COVID-19 is most transmissible when the viral load peaks, which is estimated to be within a week after infection. Those who are infected but who take a rapid test before or after the viral load peak will get a negative rapid test result – meaning that even though they are infected, they are not currently infectious. One way to reduce the risk of false negatives is with “serial testing,” where a second rapid test is performed 24-36 hours later to help catch any infectious cases that were missed with the first test.

Will the new initiatives be enough?

The White House initiatives to increase access to rapid testing are a critical step towards curbing case numbers. But one free test per person isn’t sufficient to help people resume normal activities safely. Authorizing additional inexpensive rapid tests through the Food and Drug Administration would further expand supply and reduce prices.

Making the COVID-19 vaccine free and easily accessible brought cases down quickly in the spring of 2021. Putting frequent rapid testing within reach for all could do the same now.

Beloved mall retailer files Chapter 7 bankruptcy, will liquidate

The struggling chain has given up the fight and will close hundreds of stores around the world.

Published

on

It has been a brutal period for several popular retailers. The fallout from the covid pandemic and a challenging economic environment have pushed numerous chains into bankruptcy with Tuesday Morning, Christmas Tree Shops, and Bed Bath & Beyond all moving from Chapter 11 to Chapter 7 bankruptcy liquidation.

In all three of those cases, the companies faced clear financial pressures that led to inventory problems and vendors demanding faster, or even upfront payment. That creates a sort of inevitability.

When a retailer faces financial pressure it sets off a cycle where vendors become wary of selling them items. That leads to barren shelves and no ability for the chain to sell its way out of its financial problems. 

Once that happens bankruptcy generally becomes the only option. Sometimes that means a Chapter 11 filing which gives the company a chance to negotiate with its creditors. In some cases, deals can be worked out where vendors extend longer terms or even forgive some debts, and banks offer an extension of loan terms.

In other cases, new funding can be secured which assuages vendor concerns or the company might be taken over by its vendors. Sometimes, as was the case with David's Bridal, a new owner steps in, adds new money, and makes deals with creditors in order to give the company a new lease on life.

It's rare that a retailer moves directly into Chapter 7 bankruptcy and decides to liquidate without trying to find a new source of funding.

Mall traffic has varied depending upon the type of mall.

The Body Shop has bad news for customers  

The Body Shop has been in a very public fight for survival. Fears began when the company closed half of its locations in the United Kingdom. That was followed by a bankruptcy-style filing in Canada and an abrupt closure of its U.S. stores on March 4.

"The Canadian subsidiary of the global beauty and cosmetics brand announced it has started restructuring proceedings by filing a Notice of Intention (NOI) to Make a Proposal pursuant to the Bankruptcy and Insolvency Act (Canada). In the same release, the company said that, as of March 1, 2024, The Body Shop US Limited has ceased operations," Chain Store Age reported.

A message on the company's U.S. website shared a simple message that does not appear to be the entire story.

"We're currently undergoing planned maintenance, but don't worry we're due to be back online soon."

That same message is still on the company's website, but a new filing makes it clear that the site is not down for maintenance, it's down for good.

The Body Shop files for Chapter 7 bankruptcy

While the future appeared bleak for The Body Shop, fans of the brand held out hope that a savior would step in. That's not going to be the case. 

The Body Shop filed for Chapter 7 bankruptcy in the United States.

"The US arm of the ethical cosmetics group has ceased trading at its 50 outlets. On Saturday (March 9), it filed for Chapter 7 insolvency, under which assets are sold off to clear debts, putting about 400 jobs at risk including those in a distribution center that still holds millions of dollars worth of stock," The Guardian reported.

After its closure in the United States, the survival of the brand remains very much in doubt. About half of the chain's stores in the United Kingdom remain open along with its Australian stores. 

The future of those stores remains very much in doubt and the chain has shared that it needs new funding in order for them to continue operating.

The Body Shop did not respond to a request for comment from TheStreet.

Are Voters Recoiling Against Disorder?

The headlines coming out of the Super Tuesday primaries have got it right. Barring cataclysmic changes, Donald Trump and Joe Biden will be the Republican and Democratic nominees for president in 2024.

With Nikki Haley’s withdrawal, there will be no more significantly contested primaries or caucuses—the earliest both parties’ races have been over since something like the current primary-dominated system was put in place in 1972.

The primary results have spotlighted some of both nominees’ weaknesses.

Donald Trump lost high-income, high-educated constituencies, including the entire metro area—aka the Swamp. Many but by no means all Haley votes there were cast by Biden Democrats. Mr. Trump can’t afford to lose too many of the others in target states like Pennsylvania and Michigan.

Majorities and large minorities of voters in overwhelmingly Latino counties in Texas’s Rio Grande Valley and some in Houston voted against Joe Biden, and even more against Senate nominee Rep. Colin Allred (D-Texas).

Returns from Hispanic precincts in New Hampshire and Massachusetts show the same thing. Mr. Biden can’t afford to lose too many Latino votes in target states like Arizona and Georgia.

When Mr. Trump rode down that escalator in 2015, commentators assumed he’d repel Latinos. Instead, Latino voters nationally, and especially the closest eyewitnesses of Biden’s open-border policy, have been trending heavily Republican.

High-income liberal Democrats may sport lawn signs proclaiming, “In this house, we believe ... no human is illegal.” The logical consequence of that belief is an open border. But modest-income folks in border counties know that flows of illegal immigrants result in disorder, disease, and crime.

There is plenty of impatience with increased disorder in election returns below the presidential level. Consider Los Angeles County, America’s largest county, with nearly 10 million people, more people than 40 of the 50 states. It voted 71 percent for Mr. Biden in 2020.

Current returns show county District Attorney George Gascon winning only 21 percent of the vote in the nonpartisan primary. He’ll apparently face Republican Nathan Hochman, a critic of his liberal policies, in November.

Gascon, elected after the May 2020 death of counterfeit-passing suspect George Floyd in Minneapolis, is one of many county prosecutors supported by billionaire George Soros. His policies include not charging juveniles as adults, not seeking higher penalties for gang membership or use of firearms, and bringing fewer misdemeanor cases.

The predictable result has been increased car thefts, burglaries, and personal robberies. Some 120 assistant district attorneys have left the office, and there’s a backlog of 10,000 unprosecuted cases.

More than a dozen other Soros-backed and similarly liberal prosecutors have faced strong opposition or have left office.

St. Louis prosecutor Kim Gardner resigned last May amid lawsuits seeking her removal, Milwaukee’s John Chisholm retired in January, and Baltimore’s Marilyn Mosby was defeated in July 2022 and convicted of perjury in September 2023. Last November, Loudoun County, Virginia, voters (62 percent Biden) ousted liberal Buta Biberaj, who declined to prosecute a transgender student for assault, and in June 2022 voters in San Francisco (85 percent Biden) recalled famed radical Chesa Boudin.

Similarly, this Tuesday, voters in San Francisco passed ballot measures strengthening police powers and requiring treatment of drug-addicted welfare recipients.

In retrospect, it appears the Floyd video, appearing after three months of COVID-19 confinement, sparked a frenzied, even crazed reaction, especially among the highly educated and articulate. One fatal incident was seen as proof that America’s “systemic racism” was worse than ever and that police forces should be defunded and perhaps abolished.

2020 was “the year America went crazy,” I wrote in January 2021, a year in which police funding was actually cut by Democrats in New York, Los Angeles, San Francisco, Seattle, and Denver. A year in which young New York Times (NYT) staffers claimed they were endangered by the publication of Sen. Tom Cotton’s (R-Ark.) opinion article advocating calling in military forces if necessary to stop rioting, as had been done in Detroit in 1967 and Los Angeles in 1992. A craven NYT publisher even fired the editorial page editor for running the article.

Evidence of visible and tangible discontent with increasing violence and its consequences—barren and locked shelves in Manhattan chain drugstores, skyrocketing carjackings in Washington, D.C.—is as unmistakable in polls and election results as it is in daily life in large metropolitan areas. Maybe 2024 will turn out to be the year even liberal America stopped acting crazy.

Chaos and disorder work against incumbents, as they did in 1968 when Democrats saw their party’s popular vote fall from 61 percent to 43 percent.

Veterans Affairs Kept COVID-19 Vaccine Mandate In Place Without Evidence

Authored by Zachary Stieber via The Epoch Times (emphasis ours),

The U.S. Department of Veterans Affairs (VA) reviewed no data when deciding in 2023 to keep its COVID-19 vaccine mandate in place.

VA Secretary Denis McDonough said on May 1, 2023, that the end of many other federal mandates “will not impact current policies at the Department of Veterans Affairs.”

He said the mandate was remaining for VA health care personnel “to ensure the safety of veterans and our colleagues.”

Mr. McDonough did not cite any studies or other data. A VA spokesperson declined to provide any data that was reviewed when deciding not to rescind the mandate. The Epoch Times submitted a Freedom of Information Act for “all documents outlining which data was relied upon when establishing the mandate when deciding to keep the mandate in place.”

The agency searched for such data and did not find any.

The VA does not even attempt to justify its policies with science, because it can’t,” Leslie Manookian, president and founder of the Health Freedom Defense Fund, told The Epoch Times.

“The VA just trusts that the process and cost of challenging its unfounded policies is so onerous, most people are dissuaded from even trying,” she added.

The VA’s mandate remains in place to this day.

The VA’s website claims that vaccines “help protect you from getting severe illness” and “offer good protection against most COVID-19 variants,” pointing in part to observational data from the U.S. Centers for Disease Control and Prevention (CDC) that estimate the vaccines provide poor protection against symptomatic infection and transient shielding against hospitalization.

There have also been increasing concerns among outside scientists about confirmed side effects like heart inflammation—the VA hid a safety signal it detected for the inflammation—and possible side effects such as tinnitus, which shift the benefit-risk calculus.

President Joe Biden imposed a slate of COVID-19 vaccine mandates in 2021. The VA was the first federal agency to implement a mandate.

President Biden rescinded the mandates in May 2023, citing a drop in COVID-19 cases and hospitalizations. His administration maintains the choice to require vaccines was the right one and saved lives.

“Our administration’s vaccination requirements helped ensure the safety of workers in critical workforces including those in the healthcare and education sectors, protecting themselves and the populations they serve, and strengthening their ability to provide services without disruptions to operations,” the White House said.

Some experts said requiring vaccination meant many younger people were forced to get a vaccine despite the risks potentially outweighing the benefits, leaving fewer doses for older adults.

By mandating the vaccines to younger people and those with natural immunity from having had COVID, older people in the U.S. and other countries did not have access to them, and many people might have died because of that,” Martin Kulldorff, a professor of medicine on leave from Harvard Medical School, told The Epoch Times previously.

The VA was one of just a handful of agencies to keep its mandate in place following the removal of many federal mandates.

“At this time, the vaccine requirement will remain in effect for VA health care personnel, including VA psychologists, pharmacists, social workers, nursing assistants, physical therapists, respiratory therapists, peer specialists, medical support assistants, engineers, housekeepers, and other clinical, administrative, and infrastructure support employees,” Mr. McDonough wrote to VA employees at the time.

This also includes VA volunteers and contractors. Effectively, this means that any Veterans Health Administration (VHA) employee, volunteer, or contractor who works in VHA facilities, visits VHA facilities, or provides direct care to those we serve will still be subject to the vaccine requirement at this time,” he said. “We continue to monitor and discuss this requirement, and we will provide more information about the vaccination requirements for VA health care employees soon. As always, we will process requests for vaccination exceptions in accordance with applicable laws, regulations, and policies.”

The version of the shots cleared in the fall of 2022, and available through the fall of 2023, did not have any clinical trial data supporting them.

A new version was approved in the fall of 2023 because there were indications that the shots not only offered temporary protection but also that the level of protection was lower than what was observed during earlier stages of the pandemic.

Ms. Manookian, whose group has challenged several of the federal mandates, said that the mandate “illustrates the dangers of the administrative state and how these federal agencies have become a law unto themselves.”
