Ways to Regain Sense of Smell After COVID

Among the many aftereffects of COVID-19 infection, one that has garnered much attention is the loss of smell or taste. For many people, the condition is long-term and treatment remains elusive.

Why does this happen to some people and are there effective treatments available to restore our sense of smell after COVID?

Loss of Smell Is Common With Many Viral Infections

Our sense of taste and smell work together to help us enjoy food and drink. The loss of these senses can make meals seem tasteless or bland. More importantly, we may not recognize potentially dangerous situations like a gas leak or spoiled food.

Losing taste (ageusia) and smell (anosmia) is not only an early symptom of COVID-19 infection—it’s also a well-known symptom of long COVID.

However, the condition isn’t unique to COVID.

“Loss of smell is common with numerous viral infections, and especially so in COVID. In about 95 percent, smell has returned by 6 months,” Jacob Teitelbaum, M.D., a board-certified internist and nationally known expert in the fields of chronic fatigue syndrome, fibromyalgia, sleep, and pain, told The Epoch Times.

In a study from New York University, researchers found that the presence of COVID virus near nerve cells in olfactory tissue stimulated an inrush of immune cells, like microglia and T cells to counter the infection. 

These cells release proteins called cytokines that change genetic activity in olfactory cells, even though the virus couldn’t infect them. In other scenarios, immune cell activity dissipates quickly; but researchers theorize that COVID-related immune signaling persists in a way that impairs the activity of genes needed to build smell receptors.

Other research found why, for some people, the loss is potentially permanent.

Scientists at Duke University, with experts from Harvard University and the University of California San Diego, used a tissue biopsy (extracted sample) to analyze olfactory epithelial cells, particularly those from COVID patients with long-term anosmia.

The findings indicate our immune cells may continue reacting, even when the threat is gone. 

Analyses revealed widespread infiltration by T-cells (immune cells) that caused an inflammatory response in the nose where the nerve cells for smell are located. 

“The findings are striking,” senior author Bradley Goldstein, M.D., associate professor in Duke’s Department of Neurobiology, said in a statement.

“It’s almost resembling a sort of autoimmune-like process in the nose,” he noted.

Regaining Our Sense of Smell, Steroid Nasal Spray Shows Promise

A study published in the American Journal of Otolaryngology found fluticasone (Flonase) nasal spray helped participants regain their sense of smell.

Researchers looked at 120 people experiencing anosmia due to COVID-19 and split them into two groups—one that received treatment and one that did not.

They found that smell and taste function significantly improved within one week in all patients with COVID-19 who received fluticasone nasal spray.

Teitelbaum said the nasal spray may work because viral infections can cause inflammation and swelling around the olfactory nerves. Fluticasone is an over-the-counter steroid nasal spray that reduces inflammation.

“Once the infection has been gone for a month,” advised Teitelbaum. “The OTC steroid nasal spray Flonase [used] for 6 to 8 weeks may decrease the nasal and nerve swelling.”

But he cautioned that this nasal spray shouldn’t be used while symptoms of active infection, like a runny nose, are present.

Olfactory Retraining

Anosmia has been studied long before the current pandemic. A 2009 study discovered that the sense of smell could be re-sensitized in people who lost the ability to detect odors.

Researchers exposed participants to one of four odors: cloves, lemon, eucalyptus, and rose.

Patients sniffed the four intense odors twice a day for 12 weeks. They were tested for sensitivity before and after training using “Sniffin’ Sticks” of various smell intensities.   

Compared to the baseline, patients who trained their olfactories experienced an increase in their sensitivity to smells, according to their Sniffin’ Sticks test score. Smell sensitivity was unchanged in patients who didn’t receive the sense training.

Research specifically looking at people with COVID-related loss of smell found that smell training effectively improved their ability to detect odors.

“When begun early and with good compliance, olfactory training was reported to be most beneficial in enhancing olfactory function,” said Teitelbaum.

Vitamins That May Help

There are many theories about what causes loss of smell in COVID, but we still don’t know exactly why. 

Teitelbaum believes it’s likely a mix of several causes, including low levels of certain nutrients, such as zinc.

“I give 25 to 50 mg [of zinc] a day for 6 months [to patients],” he said.

Zinc is critical for immune function, with the key immune regulating hormone called thymulin being zinc-dependent. Many infections, including AIDS, deplete zinc to worsen immunity. Smell is also zinc-dependent.

Another key nutrient for smell is vitamin A. 

“The retinol form of vitamin A at doses of 2500 to 5000 units a day may, along with zinc [at] 25 to 50 mg a day, help smell over time,” Teitelbaum recommended. 

However, pregnant women need to be careful when taking this vitamin. “Vitamin A will cause birth defects in pregnant women at doses over 8000 units,” Teitelbaum warned. 

A case study from 2021 describes how a COVID-19 patient’s ability to smell was restored by olfactory training combined with daily doses of these B-complex vitamins:

  • 5000 IU of vitamin B1  
  • 100 mg of vitamin B6  
  • 5000 mg of vitamin B12 

The patient’s anosmia was significantly improved at 12 days and his sense of smell was recovered by day 40.

Engineers Regain Control of Moon-Bound Probe After a Frightening 4 Weeks

Artist’s conception of CAPSTONE.
Image: NASA

We’ve got some good news to start the weekend: A recovery team has regained control of NASA’s CAPSTONE probe, which is in the midst of a four-month journey to an elliptical halo orbit around the Moon.

The recovery team traced the problem to a partially opened valve on one of CAPSTONE’s eight thrusters, according to an Advanced Space press release. The requisite fix was transmitted to the spacecraft yesterday and executed this morning to positive results. The probe remains on track as it heads to its operational orbit around the Moon.

CAPSTONE, short for Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, ran into difficulties following its third course correction maneuver on September 8. The 55-pound (25-kilogram) satellite lost full three-axis control and entered into a troubling tumble. A recovery team led by Advanced Space, which owns and operates CAPSTONE on behalf of NASA, scrambled to regain control of the $33 million cubesat. The probe’s propellant and propulsion system remained in a manageable state, but CAPSTONE couldn’t orient its solar panels to draw the full amount of required energy.

Launched on June 28, the cubesat is on a precursor mission for NASA’s Artemis program, which seeks a sustainable return to the Moon. To support Artemis crews, NASA and its international partners are planning to build a space station, called Gateway, in a gravitationally stable orbit known as a near-rectilinear halo orbit (NRHO). No spacecraft has ever worked in NRHO, hence the need for a scouting mission.

As Advanced Space writes in its press release, the partially open valve produced thrust in its associated thruster whenever the propulsion system was pressurized. To remedy the problem, the recovery team “conducted multiple tests on the vehicle and evaluated extensive telemetry and simulation data and then formulated a plan for attempting recovery of the vehicle’s full 3-axis control.” This recovery sequence was uploaded to the probe on Thursday and executed this morning. Advanced Space performs its joint operations with teams at Terran Orbital, which designed and built CAPSTONE.

The initial results are promising, with the new telemetry and observational data pointing to a “successful recovery of the system,” writes Advanced Space. The probe has regained three-axis control and its orientation has been corrected such that its downlink antennas are now in an ideal position for transmitting signals back to Earth. Crucially, the probe’s solar panels are now gathering energy from the Sun. “This is a major accomplishment for the mission team and positions the mission well for upcoming critical activities and arrival at the Moon,” says Advanced Space.

The company will keep a close watch on the probe in the coming days to make sure it’s truly okay. Engineers will also evaluate possible changes to operating procedures in the event of a recurrence. CAPSTONE remains on track to enter into the near-rectilinear halo orbit on November 13, with four more course correction maneuvers still required.

Dominion customers regain power in Virginia as Ian remnants sweep through

The remnants of Hurricane Ian dumped heavy rains onto parts of the Washington region Saturday, leaving tens of thousands of people without power in Virginia.

Crews set out Saturday morning to assess damage, which included broken poles and power lines, and many homes in the southeastern part of the state had their power restored by the afternoon. Dominion Energy, which serves more than 2.5 million in Virginia, expects “nearly all” of its customers will have power by Sunday evening, said Dominion spokesman Jeremy Slayton, though some customers in Hampton and Virginia Beach may not get theirs back until Monday.

Coastal flood warnings were in effect Saturday for counties along the Virginia coast, with lesser advisories in effect in Norfolk and Virginia Beach and stretching up closer to Washington. In Alexandria, businesses along the flood-prone waterfront area braced for the potential impacts of heavy rains.

The staff at Mia’s Italian Kitchen, where similar conditions last October caused flooding, piled sandbags out front. But Kevin Songster, the restaurant’s managing partner, said the ultimately “misty” weather Saturday afternoon caused no problems.

“The water was probably six inches deep on the street across from us, but it didn’t make it over,” Songster said.

Southeastern Virginia was hit hardest, and, at one, point, about 30,000 Dominion customers there were without power. That number fell to about 9,900 as evening fell Saturday.

Dominion reported nearly 12,000 of its customers were without power Saturday afternoon, down from more than 35,000 people Saturday morning. Roughly 400 customers in the Richmond area and 57 customers in Northern Virginia were also without power — down from about a thousand across both regions early Saturday.

“Our crews are working as safely and quickly as possible to ensure that all of our customers have their power restored,” Slayton said.

Meanwhile, Appalachian Power reported that roughly 17,000 of its Virginia customers also had power outages as of late Saturday afternoon, and Rappahannock Electric Cooperative reported more than 200 customers without power, according to outage maps.

Virginia Gov. Glenn Youngkin (R) declared a state of emergency ahead of the storm starting Friday, urging residents “to make a plan, have supplies on hand, and follow official sources for the latest forecast information and guidance.”

This story has been updated with new information on storm impacts.

Ground teams trying to regain control of scouting satellite for NASA’s Artemis moon program – Spaceflight Now

Ground teams will try to stabilize the motion of NASA’s small CAPSTONE scouting satellite and rescue the $30 million mission on the way to the moon, following a problem Sept. 8 that sent the spacecraft into a tumble and caused controllers to temporarily lose contact with the probe, officials said Monday.

The CAPSTONE mission is a technology demonstration and pathfinder to gather data for future NASA crew missions to the moon. The small satellite successfully departed Earth on June 28 aboard a Rocket Lab launch vehicle, starting a four-and-a-half month voyage culminating in a planned maneuver Nov. 13 to enter a halo orbit around the moon.

Rocket Lab’s Electron launcher and Photon space tug dispatched CAPSTONE on a lengthy but fuel-efficient trajectory to carry the spacecraft into deep space, well beyond the moon. CAPSTONE reached a distance of more than 950,000 miles (1.53 million kilometers) from Earth on Aug. 26, before gravity started pulling the probe onto a course to cross paths with the moon for the Nov. 13 orbit insertion burn.

More than halfway through its transit to the moon, CAPSTONE fired its miniature hydrazine propulsion system Sept. 8 for a course correction maneuver. But NASA said the spacecraft suffered a problem during or shortly after the burn, causing the spacecraft to tumble. CAPSTONE’s reaction wheels, fast-spinning devices designed to control craft’s orientation, were unable to counter the tumble motion.

The spacecraft, about the size of a microwave oven, failed to contract mission controllers after the course correction burn, giving ground teams a first sign that the mission was in trouble, according to Advanced Space, a Colorado-based company that owns and operates the CAPSTONE mission under contract to NASA. In a mission update Monday, Advanced Space said CAPSTONE is in a “dynamic operational situation.”

Advanced Space’s mission control team restored communications with CAPSTONE about 24 hours later, and telemetry from the spacecraft showed it was tumbling, its on-board computer was periodically resetting, and was using more power than it was generating from its solar panels, NASA said Monday in a statement.

Engineers from Terran Orbital, which built the CAPSTONE spacecraft, and Stellar Exploration, the propulsion system supplier, are working with Advanced Space and NASA to rescue the mission.

NASA’s worldwide network of deep space tracking and communications antennas was critical to restoring contact with CAPSTONE. The spacecraft is still tumbling, is in safe mode, but appears to be in a stable health status and is generating electricity, NASA said Monday.

But the tumbling motion means sunlight is only partially illuminating the spacecraft’s solar panels. And without accurate pointing, ground teams are only receiving weak transmissions through the spacecraft’s low gain antennas.

“Without the unique capabilities of the Deep Space Network, the mission team would have little or no information on the status of the spacecraft,” Advanced Space said.

The good news is the Sept. 8 course correction maneuver was completed, or nearly complete, when the spacecraft suffered the problem. “This means the spacecraft remains on the intended trajectory and on course to its near rectilinear halo orbit at the moon,” NASA said.

“While work is ongoing to diagnose the cause of the issue, the team is preparing CAPSTONE to attempt a detumble operation to regain attitude control of the spacecraft,” NASA said Monday. “This detumble operation was successfully demonstrated after separation from the launch upper stage in July.”

Regaining attitude control would allow the CAPSTONE spacecraft to orient its solar panels to the sun to fully recharge its batteries after consuming power during the detumble operation, NASA said. CAPSTONE would then point toward the ground to await instructions from mission control.

The recovery effort will begin by “working to improve the thermal situation of several subsystems, including the propulsion subsystem,” Advanced Space said.

“These recovery operations will be further evaluated over the coming days,” NASA said. “Recovery timing will be guided by the data and analysis available to maximize the probability of a successful spacecraft operation.”

CAPSTONE stands for the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment. The 55-pound (25-kilogram) spacecraft is designed to scout a halo-like, elongated orbit around the moon that NASA has chosen for a future mini-space station called the Gateway. The Gateway station, part of NASA’s Artemis lunar program, will serve as an experiment platform and a stopover for astronauts traveling between Earth and the surface of the moon.

No other spacecraft has flown in the unique path around the moon, called a near rectilinear halo orbit, or NRHO. The halo orbit will take CAPSTONE — and eventually the Gateway station — as close as 1,000 miles (1,500 kilometers) from the moon’s North Pole and as far as 43,500 miles (70,000 kilometers) from the South Pole. Each orbit of the moon will last about six-and-a-half days, according to NASA.

Space agency officials said before CAPSTONE’s launch in June that the pathfinder mission will collect important data, but doesn’t have to be successful to allow NASA to move forward with the Gateway program.

Like the Apollo astronauts of the past, future Artemis crew missions to the moon will travel to the halo orbit quicker than CAPSTONE, covering the quarter-million-mile distance in as few as five days.

Intelsat working to regain control of Galaxy 15 satellite

TAMPA, Fla. — Intelsat said Aug. 19 it has lost control of its Galaxy 15 satellite after it was likely hit by a geomagnetic storm.

High space weather activity likely knocked out onboard electronics needed to communicate with the satellite, Intelsat said, and keep it locked in its geostationary orbit slot at 133 degrees West.

“The satellite is otherwise operating nominally, keeping earth pointing with all payload operations nominal,” Intelsat spokesperson Melissa Longo said.

While Intelsat is working to restore its ability to command the satellite, Longo said the company expects all customers to “have service continuity” until its Galaxy 33 replacement arrives in November.

Intelsat ordered Galaxy 33 from Northrop Grumman in 2020, and SpaceX is slated to launch the satellite with Galaxy 34 on a Falcon 9 from Cape Canaveral in October.

Galaxy 15 was launched in 2005 and was built by Orbital Sciences Corporation, which is now part of Northrop Grumman.

Intelsat temporarily lost the ability to command Galaxy 15 five years after launch following an anomaly that was also pinned on unusually violent solar activity.

Longo said Intelsat is offloading customers to another satellite “to ensure service continuity,” and “will continue to try to regain command once they are off so we can eventually deorbit it.”

Galaxy 15 carries 24 C-band transponders serving media customers in North America. It also has an L-band payload used by the U.S. Federal Aviation Administration to relay GPS information to aircraft to improve navigational accuracy.

Tzu-Wei Fang, a space scientist at NOAA’s Space Weather Prediction Center (SWPC), warned Aug. 8 that the relatively benign space weather conditions of the last several years are ending. 

A new solar activity cycle set to peak around the middle of the decade may be stronger than forecast, she told the 36th Small Satellite Conference in Logan, Utah.

Police regain control of most of Canada’s capital, say protesters will continue to be identified and charged as holdouts persist

But while the big rigs, barbecues and bouncy castles were gone, major questions remained over how long the police would stay to prevent the possible return of demonstrators, and what consequences protesters — from participants up to far-right organizers — would face for the three-week-long blockade.

Tall fences have blocked off access to Wellington Street, the center of the encampments that clogged the thoroughfare running in front of Parliament and the prime minister’s office. A small contingent of holdouts remained in downtown Ottawa on Saturday night, holding a street party in open defiance of the police, who have repeatedly warned that those who remain risk arrest and fines.

“We continue to maintain a police presence in and around the area the unlawful protest occupied … to ensure the ground gained back is not lost,” the Ottawa police tweeted Sunday.

They’ve said that 103 of those arrested were charged. Police have pledged to “actively look” to identify those involved in the blockades and to “follow up with financial sanctions and criminal charges.”

Ariel Troster, a community advocate, lives in Centertown, a residential area downtown where daily life had been disrupted by the incessant honking of demonstrators and atmosphere of intimidation. Police have said that residents have been harassed for wearing masks and have faced racist vitriol.

“We are relieved to finally see some action to remove these extremists from our streets,” said Troster, 42. “But it shouldn’t have gotten this far. … I think it’s going to take a really long time and it’s going to take a lot of work to restore trust.”

Even as Ottawa residents celebrated the start of a return to normalcy, Canada’s Parliament continued to debate Prime Minister Justin Trudeau’s invocation of the 1988 Emergencies Act. Members are set to vote Monday to accept or reject use of the special powers authorized under that law.

The act is expected to pass, though some critics from both the left and the right have objected to its use. Trudeau said he needed to take the emergency measure as no other efforts to quell the “illegal and dangerous activities” affecting the country’s economy and security were working.

Bill Blair, Canada’s minister of emergency preparedness, said Sunday that “the job’s not yet done.”

“The reasons why we had to bring forward these measures, unfortunately, still exist,” he said on CTV’s Question Period.

Under the Emergencies Act, banks may freeze transactions suspected of funding the “Freedom Convoys” that paralyzed Ottawa and clogged several U.S.-Canada borders, disrupting millions of dollars a day in trade. Drivers of vehicles documented at the demonstrations can also lose their corporate bank accounts, vehicle insurance and driving licenses.

Ottawa Mayor Jim Watson told the Canadian Broadcasting Corp. that he wanted to see the Emergencies Act used to seize and sell the impounded vehicles to pay some of the costs incurred by the city.

Federal government officials said Saturday that the federal government would provide $20 million Canadian dollars ($15.7 million) to businesses affected by the protests, which authorities deemed illegal. They said 76 banks accounts worth more than $2.5 million had been frozen.

Police began to move in Friday, after 20 days of protesters having free rein in the capital’s downtown, including in residential areas. Despite tensions being high, the police response remained largely restrained, even by Canadian standards. Armed officers, some on horses and others in tactical gear, slowly moved truck-by-truck and block-by-block to push out demonstrators.

The police said they used pepper spray, stun grenades and other anti-riot weapons. Some demonstrators arrested had body armor, smoke grenades and fireworks on them, the police said Saturday.

Ontario’s Special Investigations Unit, a police watchdog, said Sunday that it was investigating two incidents from the operation to clear the blockades. One stemmed from officers discharging an anti-riot weapon and the other involved a woman who reported a serious injury after “an interaction” with a police officer on horseback.

The police have faced heavy criticism for failing to enforce laws during the convoy’s first three weeks. Critics noted that police have moved much more quickly and forcefully against other demonstrations, such as those held by Indigenous communities. The majority of “Freedom Convoy” participants were White.

Peter Sloly resigned as Ottawa police chief Tuesday under fire for his department’s handling of what he called a “siege” of the capital.

Law enforcement officials have denied that race or politics influenced their response. Rather, they have pointed to the tactical difficulties posed by the tightly packed rows of vehicles. They estimated that about 100 trucks had children living in or associated with them. Highly combustible jerrycans of fuel were also in wide circulation across the encampments.

Authorities additionally did not know if protesters were armed — and feared that items such as cooking knives, vehicles and hockey sticks could be used against them in an escalation.

Fears rose Feb. 14, when authorities said they arrested 11 people and seized guns, body armor and a “large quantity of ammunition” in Coutts, Alberta, where another convoy had been trying to block the U.S.-Canada border.

Canada’s public safety minister said Wednesday that some of those arrested in Alberta had “strong ties” to a “far-right extreme organization” with a presence in Ottawa.

Elizabeth Simons, deputy director of the Canadian Anti-Hate Network, said the group in question was Diagolon, an insurrectionist movement that has called for creating a nation-state diagonally running from Alaska through Canada’s western provinces and down to Florida.

The arrests also underscored how the “Freedom Convoy,” which focused from the outset on protesting health mandates and Trudeau’s government, was fueled in part by far-right organizers and influencers with a history of anti-government, anti-science and anti-media agendas.

Police arrested three key protest organizers — Tamara Lich, 49, Chris Barber, 46, and Patrick King, 44 — on Thursday and Friday. Barber, who was charged with mischief, obstructing police and disobeying a court order, was released on bail Friday. Under the conditions, he must leave Ottawa and cannot be in contact with or speak in support of any of the convoy’s participants or funders.

Both Lich and King remain in jail in Ottawa.

Lich, who is charged with mischief, appeared at a bail hearing Friday wearing a shirt in support of Canadian oil and gas and a court-mandated face mask. The session was adjourned until Tuesday morning, said Diane Magas, the Ottawa-based lawyer representing Lich and Barber.

Under Canada’s rules, Lich cannot fly back home to Alberta because she is unvaccinated. At the hearing, Lich’s husband, Dwayne Lich, told the court that he personally had little money but had flown to Ottawa on Feb. 2 via a private jet. He said the flight cost around $5,000 Canadian dollars ($3,900), but that a man named Joseph, whose last name he could not recall, covered his costs, Magas said.

Mischief is a wide-ranging charge that can include significant jail time. Magas said it was “too early” to say what Lich or Barber could face in terms of sentencing.

Jeffrey Monaghan, an associate professor at Carleton University’s Institute of Criminology and Criminal Justice, said that the goal of these court cases should “be trying to take momentum out of these movements.”

From a deterrence perspective, he said, when courts decide how to punish the convoy’s organizers and participants, they should consider “a form of leniency” so as to “not make martyrs out of these individuals and feed a lot of animosity.”

Wolves Will Regain Federal Protection in Much of the U.S.

Gray wolves will regain federal protection across most of the lower 48 United States following a court ruling Thursday that struck down a Trump Administration decision to take the animals off the endangered species list.

Senior District Judge Jeffrey S. White, of United States District Court for the Northern District of California, found that the United States Fish and Wildlife Service, in declaring wolf conservation a success and removing the species from federal protection, did not adequately consider threats to wolves outside of the Great Lakes and Northern Rocky Mountains where they have rebounded most significantly.

Although the decision to delist wolves came under the Trump administration, the Biden administration has defended it in court.

“Wolves need federal protection, period,” said Kristen Boyles, an attorney at Earthjustice, a nonprofit environmental law organization that has helped lead the legal fight. “The Fish and Wildlife Service should be ashamed of defending the gray wolf delisting.”

A spokeswoman for the Fish and Wildlife Service said the agency was reviewing the decision.

The Trump Administration’s decision to delist came despite concerns from some of the scientists who performed the independent review that is required before the Fish and Wildlife Service can remove a species from federal protection.

The ruling applies in 44 of the lower 48 states. Wolves in Montana and Idaho will remain unprotected because they were delisted by Congress in 2011. Wolves in Wyoming were delisted by the Fish and Wildlife Service in 2017. Wolves in New Mexico, which are considered a separate population, never lost protection.

After gray wolves were removed from the endangered species list, wolf hunting increased sharply in some states, including Wisconsin. In the spring of 2021, the state had to end its wolf hunting season early, after more than 200 wolves were killed in less than 60 hours, far exceeding the state’s quota of 119. Ojibwe tribes were furious, having decided not to fill their tribal quota because wolves have a sacred place in their culture.

Deb Haaland, the Secretary of the Interior, published an essay in USA Today this week expressing concern about threats to wolves. She said that she was alarmed by reports from Montana, where nearly 20 wolves have been killed this season after leaving the boundaries of Yellowstone National Park. The Fish and Wildlife Service, she wrote, was evaluating whether it would be necessary to relist wolves in the Northern Rockies.

Wolves were some of the first animals shielded by the 1973 Endangered Species Act, and the decision has been politically charged ever since. Big predators have long been controversial in Western states, where ranchers complain of lost livestock.

Hunter Nation, an advocacy group that filed a brief in the case, criticized the ruling. “We are disappointed that an activist judge from California decided to tell farmers, ranchers, and anyone who supports a balanced ecosystem with common-sense predator management that he knows better than them,” said Luke Hilgemann, the president and chief executive of the group.

Judge White was nominated by President George W. Bush in 2002.

Before the arrival of Europeans, gray wolves thrived from coast to coast in North America, living in forests, prairies, mountains and wetlands. But two centuries of eradication campaigns caused them to nearly disappear from the lower 48 states. By the mid-20th century, perhaps 1,000 were left south of the Canadian border, mainly in northern Minnesota.

Their numbers began to rebound after the species was placed under federal protection in the 1960s. In the mid-1990s, the Fish and Wildlife Service embarked on a new chapter of wolf conservation, relocating 31 wolves from Canada into Yellowstone National Park. Their numbers quickly increased, and in 2020 about 6,000 wolves ranged the western Great Lakes and Northern Rocky Mountains, with small numbers spreading into Oregon, Washington and California.

The United States is also home to the red wolf, a species that is listed as endangered. Its historical range included North Carolina, Tennessee and Texas.

How does COVID-19 cause people to lose sense of smell? And how many regain it?

Since the start of the COVID-19 pandemic, perhaps no symptom has been in the spotlight more than loss of smell.

Estimates vary, but it’s believed that as many as 96% of COVID-19 patients experience some or total loss — but it’s usually temporary. Most regain the sensation within weeks.

Studies have suggested that anosmia, the medical term of the condition, is a better predictor of whether someone has the virus than other symptoms such as cough or fever.

Researchers still don’t fully understand how the virus causes loss of smell, but there are a few theories.

“COVID is a brand new virus, so we don’t have all the answers yet,” Dr. Raj Sindwani, an otolaryngologist at the Cleveland Clinic, told ABC News. “Some time, we might know. But, right now, we really don’t know. These are our best guesses.”

Types of smell loss

There are two types of loss of smell that people experience from COVID-19: acute and chronic.

Acute is when a person is infected with COVID and may be experiencing other symptoms, such as a runny or stuffy nose, which inflame nasal passages.

“The particles you’re supposed to smell have to go through your nose and go to the roof of the nose, where the nerve endings are,” Sindwani explained. “If the lining is swollen and you have excess mucus production, obviously those particles aren’t going to make it up your nose as well.”

A chronic loss of smell happens after a COVID-19 infection has cleared, but, weeks or months later, a person still hasn’t regained the sense.

“There’s some point of inflammation to the nerve, damage to the nerve, whatever that virus did while it was active and damaged those nerve endings,” Sindwani said.

What are the theories?

One theory is that genetics play a role. A study published Wednesday in the journal Nature Genetics found a COVID-19 patient with a locus, or a specific place of a gene on a chromosome, near two olfactory (sense of smell) genes was linked to anosmia.

However, this genetic risk factor only increased the odds of losing sense of smell by 11%, meaning some people who had the genes didn’t lose their sense of smell, and vice versa.

“It suggests that genetics contributes to the risk, but doesn’t suggest that it is the cause of smell loss, and, if anything, suggests that it’s a small contributor,” Dr. Justin Turner, an associate professor of otolaryngology-head and neck surgery at Vanderbilt University Medical Center who was not involved in the study, told ABC News. “Because there’s many people in this study who have this genetic variability who didn’t lose their sense of smell.”

Another theory, according to a Harvard Medical School study published in July 2020, is that COVID-19 causes damage to certain cells, called sustentacular cells, that support and assist the olfactory neurons, which identify smells.

Dr. Sandeep Datta, associate professor of neurobiology in the Blavatnik Institute at Harvard Medical School and senior author of the study, said that when sustentacular cells are damaged, they are capable of regenerating and regaining their function.

However, it can take weeks or months, which may explain why many people don’t recover their sense of smell for several months.

“That’s the theory for which there is the most evidence currently,” he told ABC News.

In addition, a National Institutes of Health study from December 2020 suggested loss of smell may be from COVID-19 causing inflammation and bleeding in the part of the brain — known as olfactory bulbs — that controls sense of smell.

“It’s not clear whether the virus enters into the olfactory bulbs or not — that’s still a question — but many other viruses do,” Dr. Richard Doty, a professor in the department of otorhinolaryngology-head and neck surgery at the University of Pennsylvania, told ABC News. “Even the herpes virus can get into the brain through the olfactory pathway, so it’s not beyond a possibility. But the jury’s still out on whether the olfactory bulbs play a role” in loss of smell.

Sindwani said it’s very possible all of these theories could be true.

“Maybe it’s not one or the other, but it’s many things — what we call multifactorial,” he said. “Maybe in one patient it’s genetic, maybe in another it’s the sustentacular cells. Maybe the sustentacular cells could be a reason why the gene isn’t letting the smell be regained.”

How can COVID patients get back their sense of smell?

Sindwani said it’s very rare for COVID-19 patients to not regain their sense of smell. Studies suggest only about 5% of patients still experience anosmia after six months.

There are a couple of things that can be done to try to regain this sense. Medical treatments include using saline flushes to drain out mucus and prescription steroid sprays to decrease inflammation.

Patients also can undergo olfactory training, meaning training the nose to recognize smells again.

Just like there are primary colors — red, yellow and blue — there are primary smells: flowery, fruity, aromatic and resinous, Sindwani explained.

“You get sticks, put it under your nose, inhale for 15 to 20 seconds twice a day, and think about what, for example, roses smell like and try to remember,” he said. “The thought is that combining visual imagery with the scents of those smell particles can jumpstart to get it to work.”

Turner said he believes that stories about anosmia have brought a newfound appreciation for sense of smell to the general public.

“We typically underappreciated this sense because we may not appreciate that we’re using it as much in our daily function,” he said. “It’s not until it’s lost that we recognize how important it is.”

Utah doctor: Smell therapy helps COVID-19 patients regain sense of smell, taste

SALT LAKE CITY – Lack of smell and taste are some of the most common symptoms of COVID-19 and have affected up to 85% of patients, according to the National Institutes of Health. For some, those symptoms have lingered for months but a new therapy is showing promise.

If you’ve ever felt like up is down, or in is out, you might relate to Courtney Wightman.

“I can’t remember what garlic is supposed to smell like,” Wightman said. “I got my morning Diet Coke. I was taking sips and I was like, ‘Something tastes weird about this. It tastes like onions.'”

Her sense of smell has been off since she got COVID-19 in January. Even spa scents, like eucalyptus, are just wrong. “I can still smell that garbage smell,” Wightman said.

Smell affects taste, and severely limited her diet. “I ate SO many quesadillas. It felt like, ‘What am I living for?’ Because for me, living, is like, eating.”

Dr. Alexander Ramirez, medical director of the clinical program in otolaryngology with Intermountain Healthcare, said he’s seen success with smell therapy. He described it as physical therapy for the nose.

As part of the process, patients smell certain scents in a certain way.

“Eucalyptus, clove, lemon and rose, because that represents the spectrum,” Ramirez said. “But it’s equally as powerful to use something very strong, either something that’s terrible or good.”

He recommended doing ‘bunny sniffs,’ three short sniffs in rapid succession, rather than a long inhale through the nose, which is less effective.

Proof that the therapy works is limited, but a 2021 study published by the National Center for Biotechnology looked at a number of independent studies on smell therapy for all kinds of post-viral patients suggested it is helpful.

“Twenty seconds of that, give it a break, go to the next one, four different fragrances, twice a day for three months,” Ramirez said. You have to visualize the scent, too. “So that part of the brain can actually reroute itself and remember how to smell.”

Recovery can take 12-16 months, Ramirez said.

It’s starting to work for Wightman. “I’ve noticed just recently that it’s starting to come back and that’s super hopeful,” she said.

That devotion can lead to a sweet reward.

“Chicken and chocolate have come back so I’m really (fingers crossed) that Diet Coke is next,” she said.

Experts recommend seeing your doctor before you start smell training to make sure something else isn’t causing the problem.

It’s important to have someone else smell the essential oil to make sure the fragrance is strong.
