Host of symptoms, variable recovery times complicate return to work for those with long COVID – CBC.ca


Jessica Sewell has been on and off work since she developed long COVID last June, fighting the disease’s symptoms, which she describes as “volatile.”
“I can be OK today and able to do my job, but I get a cold and I have a two-week flare-up,” said Sewell, 28, an administrative assistant in Burnaby, B.C.
Sewell contracted COVID-19 last May, and was very sick, but said she felt well enough to return to work after her 14-day isolation. Three weeks later, she began to experience brain fog, dizzy spells, extreme fatigue and tremors. Her heart rate would shoot up to 200 beats per minute, even while standing still.
Sewell was assessed at a long COVID clinic in July. In the weeks leading up to her diagnosis, she tried to keep working because taking time off felt like “defeat,” she said.
But, “the more you push, the more [long COVID] pushes back, and it always wins,” she said.
Unclear timeline for recovery
More than 200 symptoms are associated with long COVID, affecting the brain, heart, lungs and blood vessels, according to a 2021 study published in the Lancet. The World Health Organization says symptoms can appear up to 12 weeks after even a mild infection, and can persist for months, but also “fluctuate or relapse over time.”
Doctors are grappling with how to treat patients, but there is no known cure.
Nearly two years into the COVID-19 pandemic, doctors and health experts are searching to find a cause and treatment for long COVID, while patients are simply fighting for their recovery. 6:14
Some experts fear the recent surge of infections in the Omicron wave could translate into a swell of long COVID cases in the coming months. That could have a “knock-on effect” for Canadian workplaces, in terms of illness, absences, and helping workers get back on their feet, said Peter Smith, senior scientist at the Institute for Work & Health, which studies the health and safety of working Canadians.
He pointed to pre-Omicron research that showed roughly 10 per cent of COVID-19 recoveries developed into long COVID, suggesting 170,000 Canadians were already living with the disease last fall. It’s not known whether Omicron is linked to long COVID at the same rate, but Health Canada has recorded more than 1.2 million confirmed cases of COVID-19 since the first Omicron cases on Nov. 28. (Testing issues mean many more cases may be unrecorded).
Smith said the disease might be difficult for some bosses to grasp, given the variety of symptoms, the way it flares up unexpectedly and the unclear timeline for recovery.
But he said, “it’s a missed opportunity [for employers] not to enable these people to come back to the workplace.”


Before getting sick, Sewell says she was a hard worker with plans to further her education and seek promotion. But while her employer has been understanding, she says fears this time off is harming her career prospects, and feels in limbo, not knowing if she can work from day to day.
“It makes it hard to be that dependable employee that I’m used to being,” she told The Current’s Matt Galloway.
Burden of proof is a problem
Another woman who spoke to The Current was working at a Toronto bank when she caught COVID-19 in March 2020. CBC has agreed not to name her because she fears she could face repercussions for speaking out about her employer.
She was unable to confirm the infection due to testing limitations at the time. But when unexplained symptoms — including dizziness, headaches, chest pain, muscles spasms and nausea — flared up in June 2020, her doctor diagnosed her with presumed long COVID.
By August, she was too ill to work. But when her employer insisted on proof of the original infection, she didn’t have it.
“My doctor had tried her best to support me, but she wasn’t able to provide the evidence,” she said.
She enlisted a lawyer, who helped her secure long-term disability support through her employer’s provider.
It’s time to act for all these people suffering from these debilitating conditions.– Simon Décary
Simon Décary, a professor of rehabilitation at the Université de Sherbrooke, said this burden of proof could become a problem, because testing capacity collapsed during Omicron.
While the required proof varies by workplace, Décary thinks employees with long COVID shouldn’t need a positive PCR test result to prove they were previously infected with COVID-19. Instead, health-care providers could be trained to diagnose long COVID based on the WHO definition, with that diagnosis accepted by employers, he said.
Criteria for claims changing in Ontario
On Friday, the Workplace Safety and Insurance Board announced that Ontarians who believe they contracted COVID-19 at work can make a claim without a positive PCR result, but should try to get a medical opinion or rapid test to confirm their infection.
Workplace compensation boards around the country vary on this requirement. The Saskatchewan Workers’ Compensation Board insists on a PCR test confirming the original diagnosis; while in Quebec, CNESST stipulates that priority workers who can access PCR tests will need one for a claim, but workers who cannot access PCR tests will have their claim assessed in “good faith.”
Up to Dec. 31, the WSIB has approved 31,363 claims related to COVID-19 workplace infection. The Current asked how many of those claims are related to long COVID symptoms, but the organization did not provide a figure.
In a statement, the WSIB said it provides financial support until workers are “safely able to return to work,” and that 86 per cent of claimants did so within 16-30 days.
“If people experience symptoms after they have recovered and returned to work, they could come back to us to see if they are eligible for additional benefits,” the statement continued.
As Ontario slowly reopens, COVID-19 long-haulers are still trying to adapt to their new normal. Ismaila Alfa spoke with Amara Possian about her struggles with the disease. This is the second installment of a Metro Morning series exploring how the pandemic has changed people — and what comes next. 3:29
If infected outside the workplace, workers across Canada might be left to rely on their employer’s paid sick days or health-care benefits, before applying for up to 15 weeks of employment insurance from the federal government.
In B.C., Sewell used up her sick days, then applied for provincial financial support. But a backlog in processing claims meant she had to dip into her savings.
“You’re supposed to be trying to stay stress-free … it’s hard to do that when you’re slowly watching your savings dwindle down to nothing,” she said.
Décary thinks the federal government should recognize long COVID as potential grounds for disability, to help patients access appropriate supports.
“It’s time to act for all these people suffering from these debilitating conditions,” he said.
The Current asked Health Canada whether there are plans to recognize long COVID as a grounds for disability support, but has not yet received a response.
Return to work needs communication, flexibility
In Toronto, the bank worker is still off work nearly two years after contracting COVID-19. She suffers from fatigue, heart palpitations and muscle cramps. She said her employers hired someone to fill in for her temporarily, and told her that she can return when she’s well enough, but she doesn’t know when that will be.
She said that alongside coping with her illness, she had to cope with “the stress of knowing that my employer felt that I wasn’t ill enough to be off, when I couldn’t even get out of bed.”
Smith said “trust on both sides” is key to a successful return to work for those suffering from long COVID, and it takes flexibility and frequent communication. In light of testing issues during Omicron, he thinks “we should focus less on the condition and more on what the symptoms are.”


That means patients could discuss their daily work with health-care providers, who could pinpoint what parts of their job might still be doable without inflaming their symptoms, he said.
Workers could then communicate clearly to their employers: “‘This is what I can do. This is what I’ve been told I can’t do,'” he said.
The employer could also consider temporary assignments, and try to give employees autonomy and flexibility over when tasks are completed.
Sewell contracted COVID-19 for a second time in December. But after a mild infection, she returned to work this month.
She wants employers to “lead with empathy,” and understand that the illness may be very limiting for staff.
“[Working] may be the only thing they’re going to do that day. They may be sacrificing going to their kid’s activity, or taking a shower, or having a home-cooked meal for their family,” she said.
“If we’re choosing work and being at work, just understand what that really means.”

Quebec COVID-19 hospitalizations rising as new variants gaining ground


|
MONTREAL — Quebec is seeing an increase in COVID-19 cases and hospitalizations driven by new Omicron subvariants that account for about 75 per cent of infections, the province’s public health director said Wednesday.
Dr. Luc Boileau said the subvariants, such as BA2.12.1, BA.5 and BA.4, appear to be more transmissible than previous strains but not necessarily more severe. The rise in cases was “expected,” though it came earlier than authorities had thought, he said, adding that the number of new infections should continue to rise in the coming days or weeks before declining.
Boileau said the province doesn’t plan on reimposing any broad-level public health restrictions, but he recommended that people who are over 65 or medically vulnerable take precautions such as wearing a mask. He was firm in his advice against a new provincewide masking order, insisting that such a measure was not “realistic” or necessary at this point.
“We’re not at all on a path to reimpose population-level measures such as mask-wearing, or other measures that needed to be taken in the last two years,” he said.
“We’re not there, and we’re not heading in that direction with the current variants.”
He said people who are over the age of 60, who are immunocompromised or who have chronic illnesses should seek a second booster shot if they haven’t had one or if their last shot was more than three months ago. As well, he said those who want to wear masks should be “encouraged” to do so, especially in crowded places.
His update came as COVID-19 hospitalizations rose by 34 in the previous 24 hours, after a 113-patient rise the day before. There were 1,260 people in hospital with COVID-19 in Quebec, including 35 in intensive care. Health officials also reported four more deaths associated with the novel coronavirus.
Dr. Don Vinh of the McGill University Health Centre says Quebec is facing a “perfect storm” of factors that include the emergence of new variants, waning immunity from vaccination or previous infection, and the removal of public health restrictions.
The new Omicron subvariants BA.4 and BA.5, he said in an interview Tuesday, appear to be gaining ground and finding vulnerable people to infect, especially since the mutations seem to be better able to evade immunity compared with previous strains.
“You put the two together, the new variants and waning immunity from either infection, immunization or a hybrid, and what happens is you have a renewed pool of susceptible people with an emerging variant,” he said.
The rise in hospitalizations, he added, comes at a time when the health system is least prepared to handle it.
Hospital workers at “all levels” are overwhelmed, he said, from paramedics and ambulance drivers to ER staff and the community and home care workers who need to be present to care for frail people leaving hospital.
COVID-19 is also putting increased pressure on the system by forcing sick health-care workers to stay home at a time when they’re most needed, he said. “This a catastrophic, systemic failure being unmasked and perhaps even exacerbated by unmitigated community transmission.”
On Wednesday, Boileau said he was concerned with the impact the increase in cases will have on the system, adding that authorities were working with hospitals to readjust services when necessary. He said, however, that he didn’t expect the new rise in cases to get “very, very high” and that the numbers should begin to decline in the next few weeks.

Canada extends COVID-19 border measures until Sept. 30, including ArriveCan app


|
OTTAWA — The federal government will extend current COVID-19 public health measures for travellers entering Canada, including the use of the ArriveCan app, until at least Sept. 30.
In a release Wednesday, the Public Health Agency of Canada also said it will continue the pause of mandatory random testing for fully vaccinated travellers at all airports until mid-July.
It first announced the pause on June 11 and said in the release that it’s allowing airports to focus on streamlining their operations.
The public health agency said it’s moving forward with plans to relocate COVID-19 testing for air travellers outside of airports to select test provider stores, pharmacies or by virtual appointment.
Mandatory random testing is to continue at land border points of entry with no changes.
The release added that travellers who are not fully vaccinated and don’t have a valid exemption must continue to test on Day 1 and Day 8 of their 14-day quarantine.
“As we move into the next phase of our COVID-19 response, it is important to remember that the pandemic is not over. We must continue to do all that we can to keep ourselves and others safe from the virus,” said Health Minister Jean-Yves Duclos in a statement.
He also urged people to remain up to date with the recommended vaccinations to ensure they are adequately protected against infection, transmission and severe complications.
“As we have said all along, Canada’s border measures will remain flexible and adaptable, guided by science and prudence.”
All travellers will have to continue to use the ArriveCan app or website to provide their travel information within 72 hours before their arrival in Canada or before boarding a cruise ship destined for the country. The government said 95 per cent of land and air travellers are using the app and it’s taking steps to enhance compliance.
The government also said moving testing outside of airports will allow Canada to adjust to increased traveller volumes while still being able to monitor and quickly respond to new variants of concern or changes to the epidemiological situation.
It said border testing has been essential in helping Canada slow the spread of the virus, as data from the tests are used to understand the current level and trends of importation of COVID-19 into the country.
The testing program also allows for detection and identification of new COVID-19 variants of concern, it said.
Tourism groups and border-community mayors and MPs have called on the government to ease restrictions and scrap the ArriveCan app, saying the measures are limiting cross-border travel.
Transport Minister Randy Boissonnault said the government is deeply invested in growing Canada’s visitor economy.
“From our reputation as a safe travel destination to our world-class attractions and wide-open spaces, Canada has it all and we are ready to welcome back domestic and international tourists, while prioritizing their safety and well-being.”

Western researchers use MRI to learn cause of long-COVID symptoms – BlackburnNews.com


Western researchers use MRI to learn cause of long-COVID symptoms

A study led by researchers at Western University has revealed the cause of long-COVID symptoms.
New data published by Western professor Grace Parraga and the LIVECOVIDFREE study, based out of five centres in Ontario, is the largest MRI study of patients with long-COVID. The term long-COVID refers to symptoms of brain fog, breathlessness, fatigue and feeling limited while doing everyday things, often lasting weeks and months post-infection.
This is the first study to show a potential cause of long-COVID, which has helped physicians in the study target treatment for the patients.
“I think it is always a conundrum when someone has symptoms, but you can’t identify the problem,” said Parraga, a Tier 1 Canada Research Chair in Lung Imaging to Transform Outcomes at the Schulich School of Medicine and Dentistry. “If you can’t identify the problem, you can’t identify solutions.”
By using MRI imaging with inhaled xenon gas, researchers have identified that the symptoms are caused by microscopic abnormalities that affect how oxygen is exchanged from the lungs to the red blood cells.
Researchers used the technology to watch the function of the 300-500 million tiny alveolar sacs, which are about 1/5 of a millimetre in diameter and responsible for bringing oxygen to the blood.
“What we saw on the MRI was that the transition of the oxygen into the red blood cells was depressed in these symptomatic patients who had had COVID-19, compared to healthy volunteers,” Parraga said.
Further CT scans pointed to ‘abnormal trimming’ of the vascular tree, which indicated an impact on the tiny blood vessels that deliver red blood cells to the alveoli to be oxygenated.
Parraga said the study showed no difference in severity between patients who were hospitalized with COVID-19 and those who recovered without hospitalization. She said this is an important finding as the latest wave of COVID-19 has affected many people who did not receive hospital-based care.
To conduct the study, researchers recruited patients suspected to be suffering from long-COVID from London Health Sciences Centre’s Urgent COVID-19 Care Clinic and St. Joseph’s Health Care London’s Post-Acute COVID-19 Program. Some participants experienced persistent shortness of breath more than six weeks post-infection, while others were still symptomatic after 35 weeks.
One of the participants is Alex Kopacz, a London-native and Canadian Olympic bobsleigh gold-medalist, who called his experience with COVID-19 “harrowing” and believed the virus would not affect him long-term as he is a young athlete.
“I was on oxygen for almost two months after COVID, and it took me almost three months to get to a place where I could go for a walk without gasping for air,” Kopacz said. “The take home message for me is that we have to remember that this virus can have very serious long-term consequences, which are not trivial.”
Researchers are now conducting a one-year follow-up to better understand these results.
The study was done in collaboration with researchers outside of London at Lakehead University, McMaster University, Toronto Metropolitan University and Sick Kids Hospital in Toronto.
