Are schools driving Alberta’s COVID-19 spread or are they the victim of it? Dr. Hinshaw believes the latter

Published

 on

The reopening of schools has been highlighted as a potential driver of recent COVID-19 surges in other parts of Canada and around the world, but Alberta’s chief medical officer of health doesn’t believe they are causing the high rate of new cases in this province.

“I do not see evidence in Alberta of schools driving that increasing community transmission,” Dr. Deena Hinshaw said.

“It does seem to be the reverse, with community transmission causing increased pressure in schools.”

Alberta continues to see record-high levels of COVID-19 cases among school-aged kids, but that is not unique to their demographic. Virtually every age group in Alberta has recently seen its highest rate of new cases on record, as the province experiences its largest surge in virus spread to date.

Researchers and physicians in other jurisdictions have been warning that schools may be a significant driver of COVID-19 spread, after numbers surged shortly after classes resumed.

The timing of Alberta’s latest surge is consistent with what you would expect if schools were driving an increase in spread, says Malgorzata Gasperowicz, a developmental biologist and independent researcher who has been tracking Alberta’s COVID-19 data closely.

Gasperowicz had previously warned in October that, given the trajectory in Alberta’s COVID-19 spread at the time, the province could be seeing 1,000 cases per day by Nov. 11. Alberta nearly reached that level on Nov. 7, when the province reported 919 new cases of the disease.

She noted that, after plateauing for some time throughout the summer, the disease spread suddenly accelerated in mid-September to a pace where new cases were doubling every 2½ weeks.

 

 

“It sort of switched into this faster growth around Sept. 17, which is 16 days after the schools reopening,” she said.

She cautioned that this correlation does not imply causation. In other words, it doesn’t prove schools are driving the spread, but it doesn’t rule it out.

“For me, that shows we cannot dismiss schools as a contributor to the spread,” Gasperowicz said.

Schools and COVID-19 surges in other places

Quebec experienced a similar surge of COVID-19 cases in September, and some physicians in that province have been drawing a link to the resumption of in-person classes.

“Schools were the driver to start the second wave in Quebec, although the government did not recognize it,” Dr. Karl Weiss, president of the Association des Médecins Microbiologistes Infectiologues du Québec, told the Montreal Gazette last week.

More physicians recently spoke out about the situation to CBC Montreal, noting many schools are old and have poor ventilation. Quebec has also had relatively loose requirements for students wearing masks.

Still, Quebec’s public-health director, Dr. Horacio Arruda, maintains schools are not the main cause of the province’s recent surge. He says the cases among school-aged kids are more of a reflection of transmission in the broader community.

Globally, the reopening of schools has also been connected to increases in viral-transmission rates, according to University of Edinburgh researchers who analyzed data from 131 countries and published their findings in The Lancet, a prestigious medical journal.

On Tuesday, Manitoba announced a provincewide “code red” situation due to rapid growth in COVID-19 cases. The province ordered the closure of non-essential retail stores, gyms, movie theatres, salons and churches, as well as a shutdown of recreational facilities and sports activities. Social gatherings of any kind will also be banned as of Thursday.

Manitoba schools and child-care centres will remain open, however. Despite hundreds of cases among students and staff, there have been only a small number of confirmed transmissions directly within the school system, said Manitoba’s Chief Provincial Public Health Officer Dr. Brent Roussin.

Case growth and origins

In Alberta, cases of COVID-19 have been rising quickly among older kids and teens, but not quite as fast as among the 20-to-29 age group, on a population-adjusted basis.

On average over the past week, there have been about 18 new daily cases per 100,000 people aged 10 to 19, compared with about 23 new daily cases for people in their 20s.

Case growth has been significantly slower among kids aged five to nine, at about 10 new daily cases per 100,000 children in that age range.

There’s also the source of infection to consider, which can be difficult to determine.

But Alberta Health says the data points more heavily toward non-school settings than in-school transmission.

From September to mid-October, Hinshaw said just six per cent of COVID-19 cases among school-aged kids were found to be acquired in school.

‘Invisible spread’

Alberta Health also said last week that slightly more than half of active cases — across all age groups — were of unknown origin. That figure has been increasing lately, as contact tracers struggle with the sheer volume of newly infected patients.

All this makes pinpointing the primary drivers of the recent surge in cases a difficult task.

“Everything is tangled together,” Gasperowicz said.

She noted there could also be a “data acquisition bias” when it comes to kids, in particular.

“A big percentage of children are asymptomatic, so we don’t test them,” she said. “So there could be invisible spread.”

From all the available evidence, though, Hinshaw believes schools, themselves, are not a primary driver of Alberta’s latest surge.

She says there are “many factors” that have changed since the summer that are likely contributing to the spread.

“With the fall and cooler weather, people are spending more time indoors,” Hinshaw said. “There’s less of those opportunities, perhaps, for socializing outside that we had in the summertime. And, of course, there are other activities that start up in the fall in addition to school. There’s other, recreational-type activities that people are engaging in.”

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
