Scientists are working on determining the cause behind one of the most distinctive side effects of earlier strains of COVID-19—losing one’s sense of smell.
Although this symptom has become less common as newer variants spread, back in 2020 a sudden loss of smell was an immediate sign to go get tested for COVID-19.
And although this loss of smell has been temporary for many, for others that sense never properly returned, leaving millions struggling with loss of smell for months or even years. In order to find out the mechanisms behind this, a new study looked at olfactory epithelial samples collected from 24 people, including nine people experiencing long-term loss of their sense of smell due to a case of COVID-19.
“One of the first symptoms that has typically been associated with COVID-19 infection is loss of smell,” Bradley Goldstein, associate professor in Duke’s Department of Head and Neck Surgery and Communication Sciences and the Department of Neurobiology and senior author of the new research, said in a press release.
“Fortunately, many people who have an altered sense of smell during the acute phase of viral infection will recover smell within the next one to two weeks, but some do not. We need to better understand why this subset of people will go on to have persistent smell loss for months to years after being infected with SARS-CoV2.”
According to a study published earlier this year, as many as five per cent of COVID-19 survivors have long-lasting struggles with loss of smell, coming out to estimated 15 million people. And it’s still happening, even if the rate has gone down—around 17 per cent of people lost their sense of smell due to the Omicron variant when it became dominant in 2021.
In this recent study, researchers found that among those suffering from chronic loss of smell following COVID-19 infection, there was inflammation in the tissue of the nose where the smell nerve cells are located, and that there were also fewer olfactory neurons within the nose overall compared to control groups, which researchers suspect could be due to damage from the inflammation.
In a paper published in the journal Science Translational Medicine in mid-December, researchers describe how they didn’t find any detectable SARS-CoV-2, the virus that causes COVID-19, in the subjects, but ongoing inflammation was persisting nonetheless in those with chronic smell issues.
Researchers obtained additional samples from those who had been suffering from chronic loss of smell for at least four months since contracting COVID-19. None of the patients were acutely ill with COVID-19 at the time of sampling, nor had they previously had medical interventions such as intubation.
One big issue was that in the affected patients who previously had COVID-19, part of the immune system had been thrown off balance—T-cells in the olfactory samples were working overtime, driving the inflammation.
The job of T-cells is to attack specific foreign particles in order to help the body fight a virus, but in these patients, the virus was long gone.
“The findings are striking,” Goldstein said. “It’s almost resembling a sort of autoimmune-like process in the nose.”
It’s important research into an issue that has left some without the ability to smell anything, a condition called anosmia, and others with a distorted sense of smell that impacts their ability to eat food without nausea. Parosmia is the term for when a person’s sense of smell is thrown off to the point where many things smell rancid or have a chemical cast.
Previous research on the topic has largely focused on autopsies of patients who died after having COVID-19, meaning they weren’t able to ask patients about their experiences of smell or have them take smell tests as researchers did in this new study.
Although this research answers some questions, more needs to be done to truly nail down the reason for long-term loss of smell in COVID-19 patients. The study notes that there are still several possibilities for the cause of the long-term damage, one being that the initial cell damage of the acute illness may have overwhelmed the ability of stem cells within the olfactory area to rebuild the cells responsible for smelling.
A theory seemingly disproved by this new research is that long-term loss of smell was driven by ongoing infection, which researchers found no sign of.
There were signs of hope—researchers observed neurons attempting to repair themselves even after long-term damage.
“We are hopeful that modulating the abnormal immune response or repair processes within the nose of these patients could help to at least partially restore a sense of smell,” Goldstein said.
His lab is currently working on studying this aspect of the issue. Researchers acknowledged that their current study is limited by its smaller scope.
B.C.’s economy, health care and housing to be the focus of throne speech: Eby
VICTORIA — British Columbia’s economy will be a key focus for politicians as they return to the legislature for the spring sitting.
Premier David Eby says economists are predicating a “global slowdown and potentially recession” and his government is focused on keeping the economy strong by building trade relationships and supporting businesses.
The session starts with a speech from the throne today, which Eby says will outline the government’s key priorities of health care, housing, public safety and the economy.
However, Eby won’t be there for the start of the session.
He’ll be travelling to Ottawa where Prime Minister Justin Trudeau is hosting a first ministers’ meeting to try to work out an agreement with the provinces and territories for increased funding for health care.
B.C. house leader Ravi Kahlon says the government has plans to introduce more than two dozen pieces of legislation during the session, which is set to conclude in May.
The government will table its budget at the end of the month.

Canada Facing Difficult Battle with Mental Health Struggles
Mental health is an important health issue that affects us all, and unfortunately, it’s an issue that is rarely discussed openly. According to the World Health Organization, approximately 20% of Canadians will experience a mental illness.
This makes mental health one of the most pressing issues facing Canadians today. Let’s take a closer look at why mental health is such an important issue in Canada.
The Need for Better Mental Health Care
In Canada, access to quality mental health care can be costly and difficult to obtain. Many Canadians are unaware of what services are available or how to access them due to a lack of public education about mental health.
Additionally, there is still a stigma attached to seeking help for mental illness, which can make it difficult for those who need help to get it. As a result, many people cannot access the care they need in order to live happy and healthy lives.
This deficiency can have severe consequences; untreated mental illness can lead to increased risk for suicidal behavior, substance abuse, homelessness, unemployment, and other serious problems.
Additionally, research shows that early diagnosis and treatment can help prevent long-term complications and reduce the overall costs associated with mental health treatment.
Mental health services are especially important for marginalized populations such as Black Canadians, Latinx individuals, LGBTQ+ individuals, immigrants, and individuals with low incomes who have been underserved when it comes to healthcare access.
These communities often experience higher rates of poverty and discrimination which results in an even greater need for quality mental health services but also fewer resources available to them.
Given these facts, it is clear that there is a great urgency for better access to mental health services. To make meaningful progress towards addressing this issue we must first focus on breaking down barriers such as stigma against seeking help as well as lack of information about available services among vulnerable populations.
Furthermore, a greater investment must be made into training more providers so there are enough qualified professionals available who understand how to provide culturally competent care.
Particularly when working with traditionally underserved communities – while also ensuring accessibility through reduced cost or free options for those with limited insurance coverage or financial resources.
Mental Illness as an Invisible Disease
Unlike physical illnesses, mental illnesses are often invisible and difficult to diagnose. This makes it difficult for those living with a mental illness to get the help they need as well as understand what they are going through.
It also means that many people do not realize the severity of mental illnesses and the impact they have on the lives of those living with them until they experience it firsthand or hear stories from someone who has gone through similar struggles.
Mental illness affects more people than most realize. It can be difficult to comprehend the depth of mental health disorders, as they are often invisible and misunderstood. Mental illness is a disease, yet it can remain hidden while still having a profound effect on a person’s life.
The Impact on Society
Mental illness has far-reaching effects on society as a whole. Untreated mental illness can lead to substance abuse, homelessness, unemployment, and even suicide in some cases.
All of these have ripple effects throughout our communities, from increased crime rates and lower productivity at work to higher healthcare costs and fewer resources available for those in need, making this an issue that affects us all regardless of our personal situations.
We need to create a friendly environment in which those with invisible diseases feel comfortable sharing their stories and seeking help without fear of judgment or rejection.
Mental illness should not be ignored; rather it should be treated with respect and understanding just like any other type of medical condition.
By recognizing the reality of invisible diseases such as depression, anxiety, PTSD, bipolar disorder, and more we can begin to create a world where everyone gets the help they need regardless of whether or not their condition is visible on the surface.
With understanding comes empathy, and empathy leads us toward meaningful change for ourselves and our communities alike.
Five things to know about health-care talks Tuesday between Trudeau, premiers
OTTAWA — On Tuesday in Ottawa, Canada’s 13 premiers and Prime Minister Justin Trudeau will sit around the same table in person for the first time since COVID-19 hoping to find a path toward a new long-term health-care funding deal.
Both sides are optimistic a deal will emerge but there are some big divides to overcome, including how much more money Ottawa is willing to put on the table, and how much accountability the provinces are willing to put up in return.
The premiers have been asking for a new deal for more than two years. Trudeau kept punting until the COVID-19 crisis was largely over.
That time has come.
Trudeau has been clear a deal is not going to be finished this week. But here’s a snapshot of how we got to this point, and what they’re going to be talking about.
Money, Money, Money, Money
This year Canada expected to transfer almost $88 billion to the provinces and territories for health, education, social supports and equalization. The Canada Health Transfer, or CHT, is $45.2 billion, or 51 per cent of that.
In their 2022-23 budgets, the provinces collectively forecast to spend $203.7 billion on health care. Ottawa’s transfer accounts for 22 per cent of that. The provinces want that increased to 35 per cent, which would mean $26 billion more this year alone.
“There’s been continual demands for an increase in the CHT although I’ve never seen quite as large a demand for an increase as this one,” said Gregory Marchildon, a professor emeritus at the Institute of Health Policy, Management and Evaluation at the University of Toronto.
Trudeau intends to put an offer on the table Tuesday. It will not be an immediate increase of $26 billion, but Ottawa has been silent on where it will land.
While it has existed in its current form only since 2004, some sort of federal health transfer dates from 1957, when Ottawa offered 50-50 funding for health care to provinces that agreed to provide public hospital services based on national standards.
It has evolved and changed at least five times since then, including splitting the federal share between cash and a transfer of tax points — when the federal government cut its income tax rates and the provinces could raise their own in exchange.
In 1995, then-finance minister Paul Martin, desperate to turn around Canada’s debt problems, slashed the health and social transfer by 20 per cent, followed by a 15 per cent cut in 1996. Some provinces have said their health systems have never recovered.
In 2004, a new deal was reached between the premiers and Martin, who by then was prime minister, to see the Canada Health Transfer increased six per cent a year for a decade.
The Conservatives under prime minister Stephen Harper kept that in place, but told the provinces that in 2017-18, the CHT increase would be based on a three-year average of economic growth, but with a minimum increase of at least three per cent.
Trudeau and the Liberals have maintained that.
With economic growth, the annual CHT increase has averaged five per cent since 2017-18.
Over the last 10 years, the CHT has increased 67 per cent, to $45 billion from about $27 billion in 2012-13.
An attempt in 2016 to negotiate a new CHT deal mostly failed, resulting in one-on-one agreements between Ottawa and the provinces and territories to share $11.5 billion over 10 years, beginning in 2017-18, to improve mental-health and home care.
Angling for Accountability
In the split jurisdictional world Canada’s governments live in, provinces are the ones who control health-care delivery. So for the most part, the federal government helps fund it and the provinces get to say how it’s spent.
The Canada Health Act, passed in 1984, sets out the guiding principles for recipients of the Canada Health Transfer, including that health-care systems must be universally accessible. Failing to abide by the principles can, and has, resulted in Ottawa clawing back some transfers.
Trudeau has made clear any increase to federal health transfers must be met with provincial accountability to show results. The federal government has been frustrated at the lack of accountability from provinces over transfers for health care made during COVID-19.
It is adamant that will not be the case with a new funding deal, and is looking at a combination of an annual increase to the CHT and separate deals to target specific problem areas, like health-care worker retention and training, access to family doctors, surgical backlogs, and data collection and sharing.
The 2017 deals on mental-health and home care will be a bit of a model. Those deals saw Ottawa promise $11.5 billion over 10 years for the two areas, but in exchange provinces had to agree to a common set of principles and goals, and to report results.
The Canadian Institute for Health Information was tapped to help collect and publish data. The most recent report in December is still laden with gaps and incomplete data. The reports note it will take time for the reporting to lead to change, and that provinces need to harmonize their data collection in order to better compare statistics across provincial lines.
Marchildon said one of the biggest problems for the federal government in demanding accountability is that measuring health outcomes is difficult, and hard targets are rare.
It’s all about the numbers
Of course, it’s difficult to measure progress if you’re not keeping track.
Data — or the lack of it — is a long-standing weakness of Canada’s federalized system, with 13 separate health-care systems working alongside one another but not necessarily in tandem.
In his first public overture to open negotiations with provinces on health funding in November, Health Minister Jean-Yves Duclos told provincial health ministers the federal government would increase the Canada Health Transfer if provinces agree to work together on a “world-class health data system for Canada.”
“It is the foundation for understanding what we’re doing, who’s receiving services, whether we’re making improvements,” said Kim McGrail, a professor with the University of British Columbia School of Population and Public Health.
McGrail was one of several experts the federal government tasked with reporting on what a “world-class health data system” would look like in Canada.
Gaps in Canada’s data tripped up the national health responses in dozens of different ways during the pandemic, from tracking the number of COVID-19 cases to reporting adverse effects from vaccines.
The same is true of tracking surgical backlogs and other information about how well, or not, the health system is working.
“Data informs every part of the way we think about health,” McGrail said, which includes the health of individual patients.
Canadians who move from one province to another can’t easily access their records because the technology isn’t compatible.
It’s a problem that exists even within provinces, as incompatible technology makes records inaccessible between hospitals and clinics.
“We need those technology systems to be able to talk to one another, to be able to to move data back and forth or to send messages back and forth in some way,” she said.
It’s an expensive problem to fix. Just last week, Nova Scotia government signed a $365-million contract to bring new electronic health-care records to the province, which may or may not be compatible with other provincial systems.
McGrail said investments will pay off if important information about the health of Canadians stops falling through the cracks.
The expert panel delivered a report last year that will likely serve as a road map for improving data sharing in Canada. It includes 31 recommendations, starting with provinces, territories and the federal government agreeing on a shared national vision for health data.
Ontario and Quebec have indicated a willingness to work with Ottawa on data, though other provinces have been less firm about it.
Provincial leaders have been able to agree with Ottawa on the need to reform Canada’s long-term care homes, though exactly how to accomplish that is still up for debate.
Duclos has said helping Canadians “age with dignity” is one of Ottawa’s priorities for a new health-care deal, and long-term care plays a major role in that.
So does home care, and the 2017 bilateral deals already began to advance improvements on that front.
Long-term care is an entirely different story.
The pandemic cast a glaring light on the dismal conditions in care homes across the country, when COVID-19 outbreaks led to thousands of deaths and inhumane living conditions for seniors. The military and the Red Cross were summoned to help.
In the early months of the pandemic, Canada had the worst record for COVID-19-related deaths in long-term care of the world’s wealthy countries.
Meanwhile, residents were isolated from the outside world and workers struggled to provide basic care and ensure dignity.
Experts and advocates say the problems long predate the pandemic, and have gone largely ignored until now.
“Given the devastation that we’ve seen in the COVID-19 pandemic and the impacts on our health-care system … we’re seeing this unprecedented moment where finally there’s some hope of collaboration,” said Dr. Amit Arya, a palliative care physician and founder of Doctors for Justice in Long-Term Care, which advocates for an overhaul of Ontario’s long-term care system.
Governments are now scrambling to improve the conditions, as the number of people who need specialized care grows every year and the number of workers willing to provide that care dwindles.
Several provinces have already announced plans to increase the number of hours of care residents receive per day and build new spaces for the growing number of seniors who are living longer with more serious cognitive and physical impairments.
The federal government created a $1 billion “safe long-term care fund” during the pandemic to help pay for immediate infection prevention and control measures to stop the spread of the virus.
The government also set aside $3 billion to help provinces bring homes in line with national standards for the design and operation of long-term care, though specific agreements with provinces haven’t yet been signed to deliver that money.
Those standards were publicly released last week but are unlikely to factor into the health-care talks.
Still, there is plenty of work that needs to be done if provinces have a hope of meeting the standards, especially when it comes to the workforce.
“I think we’re stepping into a crisis,” said Dr. Joseph Wong, the founder of Yee Hong Centre for Geriatric Care, the largest non-profit nursing home in the country.
He said Canada will need upwards of 100,000 new personal support workers to provide care over the next 10 to 15 years in order to provide adequate care to residents.
“It is a time bomb,” he said.
The same could be said of the health system at large.
None of the lofty goals of the federal or provincial politicians will be possible if they don’t find a way to persuade workers to stay in hospitals, clinics and long-term care centres across Canada, said Linda Silas, president of the Canadian Federation of Nurses Unions.
“They don’t have the staff to do the job,” she said.
Staff shortages have been the common theme among some of the most serious issues underlying the public-health crisis in Canada.
Dozens of emergency rooms have been forced to close temporarily or reduce hours because there weren’t enough staff to treat urgent injuries and illnesses. The Canadian Medical Association estimates nearly five million Canadians don’t have a family doctor. And hundreds of thousands of Canadians are sitting on wait-lists for backlogged surgeries and diagnostic tests.
Health unions and professional associations want a national strategy to keep doctors, nurses and personal support workers in their jobs as well as train new staff to bolster their ranks.
Silas said after years of burnout and moral distress over not being able to care for their patients properly, nurses in particular have said, “I’ve had enough.”
Nurses in Ontario have also balked at a law limiting pay increases to one per cent a year.
Data from the Canadian Institute for Health Information shows that because of new graduates, the supply of nurses is still growing. However, many have chosen not to take full-time positions, and existing staff are increasingly eyeing early retirement, Silas said.
The heavier demands of the job since the pandemic, combined with fewer and fewer people to do the work, has created what even the federal health minister calls a crisis.
“We need to stop the bleed,” Silas said.
