What 2 new studies reveal about long COVID in Canada

Published

 on

Two new large-scale reports are giving a clearer picture of the long-term impacts of COVID-19 infections on Canadians and the health-care system.

One report, published Monday by Statistics Canada, found that nearly 15 per cent of people who’ve contracted COVID-19 say they experienced lingering symptoms such as fatigue, shortness of breath or brain fog three months or more after their initial infection.

But compared with earlier phases of the pandemic, the report found that a much smaller proportion of those infected since the Omicron variant hit Canada late last year reported such long-term symptoms.

StatsCan, which conducted the survey in partnership with the Public Health Agency of Canada, describes it as the first nationally representative report of its kind.

A separate study also published Monday, in the Canadian Medical Association Journal (CMAJ), found that people who tested positive for COVID-19 in Ontario used more hospital and other health-care resources in the months after their infection cleared than those who tested negative.

The reports are the latest in a growing body of research into the scope of long COVID, a catch-all term for a range of post-infection health effects.

Fewer people report long COVID since Omicron: survey

The World Health Organization has estimated that what it calls “post-COVID-19 condition” affects 10 to 20 per cent of those infected, but those figures are based on earlier phases of the pandemic. Newer research suggests long COVID is now occurring at a much lower rate.

StatsCan says its data suggests some 1.4 million Canadian adults — or about five per cent of the total population — experienced symptoms three months after a COVID infection. The survey was conducted among Canadians who tested positive for COVID-19 or suspected they had the disease.

“This is a significant number of people impacted by long COVID,” said Dr. Fahad Razak, an internal medicine specialist and epidemiologist at St. Michael’s Hospital in Toronto, and a former head of Ontario’s COVID-19 science advisory table.

“Clinicians in Canada’s research community have been waiting anxiously for the results of this and the data does tell us that we are like other countries,” said Razak, who was not directly involved in the study, in an interview with CBC News.

Because the survey data is based on people’s self-reports of post-COVID symptoms and isn’t compared with a control group of uninfected people, Razak and other physicians said the results should be interpreted with some caution.

The StatsCan report does not indicate how severe people’s post-COVID symptoms were, nor does it indicate whether symptoms waned at any point after the three-month mark.

StatsCan’s survey found that a notably smaller proportion of people infected since the Omicron wave report long-term symptoms, compared with those infected during the first year and a half of the pandemic.

The survey found 25.8 per cent of Canadian adults who contracted COVID-19 before December 2021 had symptoms at least three months after their infection.

Among those whose cases date from December 2021 onward, 10.5 per cent reported symptoms three months or more post-infection.

The lower rate of long COVID among Canadians infected since last December is good news, says Dr. Zain Chagla, an infectious diseases specialist in Hamilton, who was not involved in the study.

“The people that are really, really suffering the most are people that were infected very early in the pandemic,” said Chagla in an interview with CBC News.

Vaccines likely key to lower frequency: doctors

Both Chagla and Razak said the benefit of vaccination is likely a key reason for the lower frequency of long COVID among those infected over the past year.

The survey also provides further evidence linking the likelihood of long COVID with the severity of illness when first infected.

Symptoms at least three months post-infection were reported by:

  • 36.4 per cent of Canadian adults who rated their initial case of COVID-19 as severe;
  • 15 per cent of those who rated their initial case as moderate;
  • 6.3 per cent of those who rated their initial case as mild.

Dr. Angela Cheung, senior physician scientist with the University Health Network in Toronto, said those figures from the Statistics Canada report are consistent with previous research.

“I’m glad this survey happened and that we are actually trying to get a handle on the number of people affected by COVID-19 with lingering symptoms,” she said in an interview.

Findings can help prepare for demand, researchers say

Cheung, who was not involved with either report, also said the CMAJ study published Monday is important for quantifying increased use of the health-care system after a COVID-19 infection.

The study led by researchers from Toronto’s Sunnybrook Research Institute and at the non-profit research agency ICES looked at the health-care use of more than 530,000 Ontario residents who were tested for COVID-19 via PCR before March 31, 2021.

The researchers matched the demographics of those who tested positive and those who tested negative and found “significantly higher rates of health care use” in the period starting at least eight weeks after a positive test.

The researchers found a 47 per cent increase in the average number of days spent in hospital per year by women who’d tested positive and a 53 per cent average increase among men.

The researchers said the findings can help the system prepare for health-care demand associated with long COVID.

As sports betting addiction takes hold in Brazil, the government moves to crack down

Published

 on

SAO PAULO (AP) — “King” doesn’t disclose his real name. Even clients of his Sao Paulo newsstand have to call him by his moniker. The Brazilian online sports gambling addict lowered his profile after a loan shark threatened to put bullets in his head if he didn’t pay up.

Broke and embarrassed, King sought treatment and support earlier this year.

“I was once addicted to slot machines, but then sports betting was so easy that I changed. I got carried away all the time,” he told The Associated Press.

King’s story is that of many vulnerable Brazilians in recent years. The country has become the third-biggest market in the world for sports betting, following the U.S. and the U.K., a report by data analysis company Comscore said last year. But unlike those countries, rampant advertising and sponsorship have been coupled with an unregulated market. The government is now — belatedly, some say — striving to get a handle on the epidemic.

On a recent evening, King’s Gamblers Anonymous meeting took place in an improvised classroom inside a church, with coffee and cookies to keep everyone awake, and supportive messages scrawled onto the blackboard. One that’s become ubiquitous in Brazil and beyond: “Only for today I will avoid the first bet.”

King and other attendees, all Christian, started a prayer and the meeting began.

King said his financial problems arose from his addiction to online sports betting, chiefly on soccer.

“I miss the adrenaline rush when I don’t bet,” he said before the gathering. “I have managed to stop for a couple of months, but I know that if I do it once again, even a small bet, it will all come back.”

Driven by the pandemic

The COVID-19 pandemic was a key driver for Brazilians embracing sports betting. King said he transformed almost every sale during that time into a bet. His hook was the non-stop advertising on TV, radio, social media as well as sponsorship of local soccer teams’ jerseys. He asked for bank loans to pay his gambling debts and then, to cover those, went to the moneylender. His total debt now amounts to 85,000 reais ($15,000) — impossible to pay off with his monthly income of 8,000 reais.

Digging oneself out of debt in Brazil is especially daunting with its sky-high interest rates. Loans from Brazilian banks could add interest of almost 8% per month to the borrowed sum, and from loan sharks could be even more.

Four Gamblers Anonymous meetings attended by the AP in October featured discussions about difficulties paying down debts, forcing working-class members to postpone housing payments and cancel family vacations.

Some members of impoverished Brazilian families have used welfare money for betting instead of paying for groceries and housing, official data suggests. In August, beneficiaries of Brazil’s flagship program Bolsa Familia spent 3 billion reais ($530 million) on sports betting, according to a report from the central bank. That was more than 20% of the program’s total outlay in the month.

A host of gambling related problems

Sports betting was made legal in 2018 in a bill signed by former President Michel Temer. The subsequent turmoil has recently been setting off alarm bells, with addicts venting on social media and media reports of people losing huge sums.

On Oct. 1, the economy ministry prevented more than 2,000 betting companies from operating in Brazil for having failed to provide all the required documents. Soccer-loving President Luiz Inácio Lula da Silva said in an interview on Oct. 17 that he will shut down the entire market in Brazil if his administration’s new regulations — presented at the end of July— fail to work. And Brazil’s Senate on Oct. 25 opened an investigation into betting companies, focusing on crime and addiction.

“There’s tax evasion, money laundering of organized crime, the use of influencers to trick people into betting. These companies need to be audited,” Sen. Soraya Thronicke, who proposed the inquiry, told journalists in Brasilia.

Sérgio Peixoto, a ride-sharing app driver in Rio, is one of many lower-middle-income Brazilians who have reduced their spending due to sports betting debt. Peixoto’s debt currently amounts to 25,000 reais ($4,400). His monthly income is four times less than that.

“It stopped being a game, it wasn’t fun. I just wanted to get the money back, so I lost even more,” said Peixoto, 26. “I could have invested that money. It would surely have given me more benefits.

Pressure to bet

Pressure on people to gamble is everywhere. Current and former soccer players, including Vinicius Júnior, Ronaldo Nazário and Roberto Rivellino, are among the poster boys for local and foreign brands. All but one of the top-tier soccer clubs have betting companies among their main sponsors, with their name and logo emblazoned on their kits. There have been cases of kids and teenagers setting up accounts using their parents’ personal information and money, multiple local media outlets have reported.

Brazil’s economy ministry estimates that Brazil’s sports betting market had $21 billion in transactions last year, a 71% increase compared with the first year of the pandemic, 2020.

The ministry’s newly presented regulations include facial recognition systems for gamblers to bet, the identification of a single bank account for transactions involving sports betting, new protections against hackers and the government-authorized domain, bet.br, which will host all betting sites that are legal in Brazil. Once they are in place, come January, between 100 and 150 betting companies will continue to operate in the South American nation.

The changes in Brazil have prompted some companies to take preemptive action. A report by Yield Sec, a technical intelligence platform for online marketplaces, said several betting companies voluntarily restricted their operations in different places after the latest editions of the European Championships and Copa America in the hopes of presenting “the best possible license application face to the Brazilian authorities.”

Magnho José Santos de Sousa, the president of the Legal Gambling Institute, a betting think tank, said Brazil is currently “invaded by illegal websites that have licenses in Malta, Curação, Gibraltar and the United Kingdom.”

De Sousa expressed hope that the new regulations for advertising, responsible gambling and qualification of sports betting companies will transform the country’s deregulated arena into a more serious one that doesn’t exploit the vulnerable.

“The whole operation could turn from water into wine,” he said.

Gamblers Anonymous in high demand

Meantime, the demand for Gamblers Anonymous meetings in Sao Paulo has grown so much in recent years that the weekly gathering, in place since the 1990s, was no longer enough. Many groups have added a second day in the week to help new people recover, mostly sports bettors.

Earlier in October, a group on Sao Paulo’s northern edge admitted a man who was struggling with sports betting and card games. The 13 other people in the room stressed that he wasn’t alone.

“Welcome,” one long-time attendee said, in a greeting that has become a regular for the group. “Today, you are the most important person here.”

Oilers fall 4-2 to Golden Knights in McDavid’s return from injury

Published

 on

EDMONTON – Noah Hanifin had a pair of goals as the Vegas Golden Knights won their first road game of the season, coming from behind to shock the Edmonton Oilers 4-2 on Wednesday.

Jack Eichel had a goal and two assists and Mark Stone also scored for the Golden Knights (9-3-1), who have won two in a row and six of their last seven. The Knights entered the game 0-3-1 on the road this year.

Brett Kulak and Zach Hyman replied for the Oilers (6-7-1), who have lost two straight despite getting captain Connor McDavid back from injury earlier than expected for the game.

Adin Hill made 27 saves for Vegas, while Stuart Skinner managed 31 stops for Edmonton.

Takeaways

Golden Knights: With an assist on the Knights’ second goal, William Karlsson has recorded at least a point in all five games he has played this season (two goals, four assists).

Oilers: McDavid was a surprise starter for the Oilers, coming back just nine days after suffering an ankle injury in Columbus and initially being expected to miss two to three weeks. The star forward came into the contest with 11 points (three goals, eight assists) during a six-game point streak versus the Golden Knights, but was held pointless on the night.

Key moment

With just 48.4 seconds left to play, the Golden Knights won a race to the corner and Ivan Barbashev was able to send it out to a hard-charging Hanifin, who sent a shot glove-side that beat Skinner for his second goal of the third period and third of the season.

Key stat

It was Hyman’s third goal in the last four games after the veteran forward went scoreless in his first 10 games this season following a 54-goal campaign last year. Hyman now has five goals in his last six games against Vegas.

Up next

Golden Knights: Head to Seattle to face the Kraken on Friday.

Oilers: Travel to Vancouver on a quick one-game trip to clash with the Canucks on Saturday.
