School outbreaks of COVID-19 will happen. Doctors offer tips to keep them in check – CBC.ca

Published

 on


As schools across Canada finalize their back-to-class plans, doctors say there are a few things educators and parents should keep in mind during COVID-19.

People will form new routines that build on the advice provincial medical officers of health regularly share about hand washing, avoiding touching your face and trying to keep two metres away from others. Schools will now put students into smaller groups, check ventilation and consider use of masks.

Cases of COVID-19 haven’t overwhelmed health systems in Canada thanks to collective sacrifices, but cases continue to occur. 

CBC News is breaking down need-to-know information on the pandemic based on questions sent via email to COVID@cbc.ca. Here, physicians offer advice and answer questions on back-to-school topics like distancing, health checks, safe nap times and when to stay home.

Dr. Lisa Barrett, an infectious diseases physician at Dalhousie University in Halifax, said keeping school as safe as possible for kids to learn and socialize doesn’t follow a set timetable.

By necessity, she said, school plans can’t be perfect and people won’t follow all of the basics to the letter at all times.

“If we don’t do a better job of tracking and tracing, then some of these school plans … are going to fail, and we’re going to see outbreaks and clusters we can’t control,” she said.

Layering public health measures for all Canadians on top of testing and contact tracing aims to keep outbreaks manageable. 

Priority 1: Keep COVID-19 out

Many school boards have not yet offered details on what they’ll be implementing to keep children safe and how. Until then, infectious disease and public health experts say some precautions will be the most effective.

Infectious disease physicians stress prevention before control — meaning they’d like to keep the novel coronavirus out of schools altogether.

That’s why they, along with pediatricians and epidemiologists, repeat that people need to stay home when sick. Doing so prevents an individual’s illness from sparking more.

Dr. Laura Sauvé, a pediatric infectious disease specialist at the University of British Columbia, said public health, school authorities and infectious disease specialists are collaborating closely across the country.

“Public health authorities are trying their best to balance multiple competing priorities keeping in mind the whole child,” Sauvé said.

Priority 2: Check frequently for symptoms

Recognizing a sickness and acting on it is a major layer of defence to keep COVID-19 out of schools.

Sauvé’s son is heading into Grade 4. When he attended day camp in B.C. this summer, she said there were either sign-in sheets or a daily email requiring parents to declare the child is not sick.

“It’s not so much the signing. It’s the fact that every day we’re checking in with ourselves and saying, ‘Am I sick today? Do I have any symptoms?'” she said. “And if there’s any way I could have symptoms, I need to stay away and reassess. If I get worse, get a test.”

To emphasize the stay-home message, schools and workplaces plan to send notices home, and provincial health officers will give regular reminders, she said.

Priority 3: Stay apart

Public health experts have repeatedly stressed that physical distancing is key to preventing the spread of COVID-19, but how that will play out in schools with small classrooms and large numbers remains to be seen.

Andisha A., a Grade 11 student in Calgary, sent the this question to Ask CBC: “How can I be safe when my classroom is full, with not a lot of social distancing going around? The school board is also not forcing students to wear a mask?”

The federal government’s COVID-19 guidance for schools resource emphasizes separating people from each other through physical distancing and barriers as more protective than what individuals can do, such as covering coughs, hand washing or wearing non-medical masks.

To that end, local medical officers of health in Toronto, Hamilton and Ottawa have called for smaller class sizes.

“Ottawa Public Health supports having the number of students within a classroom to be as small as possible, in order to facilitate appropriate physical distancing, and to maintain distancing and limit the mixing of cohorts in common areas such as hallways and washrooms,” Dr. Brent Moloughney, the city’s associate medical officer of health said in a statement on Tuesday.

Provincial recommendations to school boards are also subject to change.

Masks are another issue school boards are tackling differently. In Alberta, students from Grades 4 through 12 will be required to wear masks in all public spaces like hallways and can choose to wear them while seated in the class. Masks will be optional for younger students. Quebec’s plans are similar. Ontario requires masks in Grades 4 to 12.

Priority 4: Ventilation  

Lorna C. asked, “What is the plan to ensure safe air flow and humane working temperatures in elementary schools without air conditioning?”

At her clinic, Sauvé said fans are generally avoided to prevent the spread of fungal spores but they are turned on since it can get as hot as 35 C inside.

For schools, Sauvé said opening windows is encouraged.

Provincial occupational health and safety committees have more specific recommendations on ventilation in school. 

Priority 5: Personal protective equipment

Dr. Catherine Clase, a nephrologist at St. Joseph’s Healthcare in Hamilton, Ont., applauds Andisha for being proactive about staying safe at school 

Clase suggests fabric masks for students, which she first proposed for her kidney patients. Some school boards across Canada are making masks mandatory for secondary school students. 

“If [masks] are normalized in school and we have conversations and kids are not shamed for doing it wrong I think that’s going to be really important,” Sauvé said. “Everything we do has to be done with the thought of kindness and support.” 

Clase hopes people will create shareable videos to encourage proper use.

Making masks attractive to children would help and some trial and error could be in order, she said.

Sauvé suspects that with encouragement and redirection, most children will be able to get used to wearing masks, which are not the “be all and end all” of protection.

Monica N. asked about how often to change a mask during a six-hour day with Grade 3 students. 

If families have the resources, then both Clase and Sauvé suggest providing two facial coverings each day to change at lunch or if one becomes soiled.

“We need to be planning for at least one clean mask for every person going outside the house every morning,” Clase said.

Hand sanitizer and spaced-out desks, labelled for a specific cohort of student, are some of the changes being made in secondary schools. (Stacey Janzer/CBC)

Sophie D. said “physical distancing is not possible with infants, toddlers, or preschoolers, especially during nap time when up to 24 children sleep on cots close together. Will masks really protect educators in this environment?”

Likely, yes. “You will get protection from wearing a mask,” Clase said.

Sauvé said sleeping children are also not coughing and running around.

“Evidence suggests that toddlers would transmit less than a 20-year-old having a nap.”

Schools aren’t the most dangerous place

Doctors and scientists also know more about the virus than when schools abruptly closed back in March, when the pandemic was taking hold in Canada.

The bulk of evidence globally shows some kids will get very sick with COVID-19, but overall they get much milder disease symptoms than adults, Sauvé said.

“Of kids who get it, about 80 per cent get it from somebody in their household … even in settings where kids are getting back to school and back to daycare,” she said.

It also appears that young children transmit the virus less than older kids. There’s no clear age cutoff, according to Sauvé.

Health Canada approves updated Novavax COVID-19 vaccine

Published

 on

 

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

The protein-based vaccine, called Nuvaxovid, has been reformulated to target the JN.1 subvariant of Omicron.

It will replace the previous version of the vaccine, 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.

Earlier this week, Health Canada approved Moderna’s updated mRNA COVID vaccine.

It is still reviewing Pfizer’s updated mRNA vaccine, with a decision expected soon.

This report by The Canadian Press was first published Sept. 19, 2024.

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.”
